Duck is the common name for a large number of species in the waterfowl family Anatidae which includes swans and geese. Ducks are divided among several subfamilies in the family Anatidae. Ducks are aquatic birds smaller than the swans and geese, may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes and coots; the word duck comes from Old English *dūce "diver", a derivative of the verb *dūcan "to duck, bend down low as if to get under something, or dive", because of the way many species in the dabbling duck group feed by upending. This word replaced Old English ened/ænid "duck" to avoid confusion with other Old English words, like ende "end" with similar forms. Other Germanic languages still have similar words for "duck", for example, Dutch eend "duck", German Ente "duck" and Norwegian and "duck"; the word ened/ænid was inherited from Proto-Indo-European. A duckling is a young duck in downy plumage or baby duck, but in the food trade a young domestic duck which has just reached adult size and bulk and its meat is still tender, is sometimes labelled as a duckling.
A male duck is called a drake and the female is called a duck, or in ornithology a hen. The overall body plan of ducks is elongated and broad, the ducks are relatively long-necked, albeit not as long-necked as the geese and swans; the body shape of diving ducks varies somewhat from this in being more rounded. The bill is broad and contains serrated lamellae, which are well defined in the filter-feeding species. In the case of some fishing species the bill is long and serrated; the scaled legs are strong and well developed, set far back on the body, more so in the aquatic species. The wings are strong and are short and pointed, the flight of ducks requires fast continuous strokes, requiring in turn strong wing muscles. Three species of steamer duck are flightless, however. Many species of duck are temporarily flightless; this moult precedes migration. The drakes of northern species have extravagant plumage, but, moulted in summer to give a more female-like appearance, the "eclipse" plumage. Southern resident species show less sexual dimorphism, although there are exceptions like the paradise shelduck of New Zealand, both strikingly sexually dimorphic and where the female's plumage is brighter than that of the male.
The plumage of juvenile birds resembles that of the female. Over the course of evolution, female ducks have evolved to have a corkscrew shaped vagina to prevent rape. Ducks eat a variety of food sources such as grasses, aquatic plants, insects, small amphibians and small molluscs. Dabbling ducks feed on the surface of water or on land, or as deep as they can reach by up-ending without submerging. Along the edge of the beak, there is a comb-like structure called a pecten; this strains the water squirting from traps any food. The pecten is used to preen feathers and to hold slippery food items. Diving ducks and sea ducks forage deep underwater. To be able to submerge more the diving ducks are heavier than dabbling ducks, therefore have more difficulty taking off to fly. A few specialized species such as the mergansers are adapted to swallow large fish; the others have the characteristic wide flat beak adapted to dredging-type jobs such as pulling up waterweed, pulling worms and small molluscs out of mud, searching for insect larvae, bulk jobs such as dredging out, turning head first, swallowing a squirming frog.
To avoid injury when digging into sediment it has no cere, but the nostrils come out through hard horn. The Guardian published an article advising that ducks should not be fed with bread because it damages the health of the ducks and pollutes waterways. Ducks are monogamous, although these bonds last only a single year. Larger species and the more sedentary species tend to have pair-bonds that last numerous years. Most duck species breed once a year. Ducks tend to make a nest before breeding, after hatching, lead their ducklings to water. Mother ducks are caring and protective of their young, but may abandon some of their ducklings if they are physically stuck in an area they cannot get out of or are not prospering due to genetic defects or sickness brought about by hypothermia, starvation, or disease. Ducklings can be orphaned by inconsistent late hatching where a few eggs hatch after the mother has abandoned the nest and led her ducklings to water. Most domestic ducks neglect their eggs and ducklings, their eggs must be hatched under a broody hen or artificially.
Female mallard ducks make the classic "quack" sound while males make a similar but raspier sound, sometimes written as "breeeeze", but despite widespread misconceptions, most species of duck do not "quack". In general, ducks make a wide range of calls, ranging from whistles, cooing and grunts. For example, the scaup – which are diving ducks – make a noise like "scaup" (hence
The Atlantic Ocean is the second largest of the world's oceans, with an area of about 106,460,000 square kilometers. It covers 20 percent of the Earth's surface and about 29 percent of its water surface area, it separates the "Old World" from the "New World". The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, the Americas to the west; as one component of the interconnected global ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, the Southern Ocean in the south. The Equatorial Counter Current subdivides it into the North Atlantic Ocean and the South Atlantic Ocean at about 8°N. Scientific explorations of the Atlantic include the Challenger expedition, the German Meteor expedition, Columbia University's Lamont-Doherty Earth Observatory and the United States Navy Hydrographic Office; the oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC: Atlantikoi pelágei and in The Histories of Herodotus around 450 BC: Atlantis thalassa where the name refers to "the sea beyond the pillars of Heracles", said to be part of the sea that surrounds all land.
Thus, on one hand, the name refers to Atlas, the Titan in Greek mythology, who supported the heavens and who appeared as a frontispiece in Medieval maps and lent his name to modern atlases. On the other hand, to early Greek sailors and in Ancient Greek mythological literature such as the Iliad and the Odyssey, this all-encompassing ocean was instead known as Oceanus, the gigantic river that encircled the world. In contrast, the term "Atlantic" referred to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast; the Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of millions of years ago. The term "Aethiopian Ocean", derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century. During the Age of Discovery, the Atlantic was known to English cartographers as the Great Western Ocean; the term The Pond is used by British and American speakers in context to the Atlantic Ocean, as a form of meiosis, or sarcastic understatement.
The term dates to as early as 1640, first appearing in print in pamphlet released during the reign of Charles I, reproduced in 1869 in Nehemiah Wallington's Historical Notices of Events Occurring Chiefly in The Reign of Charles I, where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank, Charles I's Secretary of State. The International Hydrographic Organization defined the limits of the oceans and seas in 1953, but some of these definitions have been revised since and some are not used by various authorities and countries, see for example the CIA World Factbook. Correspondingly, the extent and number of oceans and seas varies; the Atlantic Ocean is bounded on the west by South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea. To the east, the boundaries of the ocean proper are Europe: the Strait of Africa. In the southeast, the Atlantic merges into the Indian Ocean; the 20° East meridian, running south from Cape Agulhas to Antarctica defines its border.
In the 1953 definition it extends south to Antarctica, while in maps it is bounded at the 60° parallel by the Southern Ocean. The Atlantic has irregular coasts indented by numerous bays and seas; these include the Baltic Sea, Black Sea, Caribbean Sea, Davis Strait, Denmark Strait, part of the Drake Passage, Gulf of Mexico, Labrador Sea, Mediterranean Sea, North Sea, Norwegian Sea all of the Scotia Sea, other tributary water bodies. Including these marginal seas the coast line of the Atlantic measures 111,866 km compared to 135,663 km for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 or 23.5% of the global ocean and has a volume of 310,410,900 km3 or 23.3% of the total volume of the earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 and has a volume of 305,811,900 km3; the North Atlantic covers 41,490,000 km2 and the South Atlantic 40,270,000 km2. The average depth is 3,646 m and the maximum depth, the Milwaukee Deep in the Puerto Rico Trench, is 8,486 m.
The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge. It runs from 87°N or 300 km south of the North Pole to the subantarctic Bouvet Island at 42°S; the MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2,000 m along most of its length, but is interrupted by larger transform faults at two places: the Romanche Trench near the Equator and the Gibbs Fracture Zone at 53°N; the MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the othe
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
United States National Forest
National Forest is a classification of protected and managed federal lands in the United States. National Forests are forest and woodland areas owned collectively by the American people through the federal government, managed by the United States Forest Service, a division of the United States Department of Agriculture; the National Forest System was created by the Land Revision Act of 1891, signed under the presidency of Benjamin Harrison. It was the result of concerted action by Los Angeles-area businessmen and property owners who were concerned by the harm being done to the watershed of the San Gabriel Mountains by ranchers and miners. Abbot Kinney and forester Theodore Lukens were key spokesmen for the effort. In the United States there are 155 National Forests containing 190 million acres of land; these lands comprise 8.5 percent of the total land area of the United States, an area about the size of Texas. Some 87 percent of National Forest land lies west of the Mississippi River in the mountain ranges of the Western United States.
Alaska has 12 percent of all National Forest lands. The U. S. Forest Service manages all of the United States National Grasslands, around half of the United States National Recreation Areas. There are two distinctly different types of forests within the National Forest system; those east of the Great Plains in the Midwestern and Eastern United States were acquired by the federal government since 1891, may be second growth forests. The land had long been in the private domain and sometimes logged since colonial times, but was purchased by the United States government in order to create new National Forests; those west of the Great Plains in the Western United States, though established since 1891, are on lands with ownership maintained by the federal government since the U. S. acquisition and settling of the American West. These are lands that were kept in the public domain, with the exception of inholdings and donated or exchanged private forest lands. Land management of these areas focuses on conservation, timber harvesting, livestock grazing, watershed protection and recreation.
Unlike national parks and other federal lands managed by the National Park Service, extraction of natural resources from national forests is permitted, in many cases encouraged. However, the first-designated wilderness areas, some of the largest, are on National Forest lands. There are management decision conflicts between conservationists and environmentalists, natural resource extraction companies and lobbies, over the protection and/or use of National Forest lands; these conflicts center on endangered species protection, logging of old-growth forests, intensive clear cut logging, undervalued stumpage fees, mining operations and mining claim laws, logging/mining access road-building within National Forests. Additional conflicts arise from concerns that the grasslands and forest understory are grazed by sheep, and, more rising numbers of elk and mule deer due to loss of predators. Many ski resorts and summer resorts operate on leased land in National Forests. List of U. S.

Jimmy Carter National Historic Site
The Jimmy Carter National Historic Site, located in Plains, preserves sites associated with James Earl "Jimmy" Carter, Jr. 39th President of the United States. These include his residence, boyhood farm and the town railroad depot, which served as his campaign headquarters during the 1976 election; the building which used to be Plains High School serves as the park's visitor center. As President Carter lives in Plains, the area surrounding the residence is under the protection of the United States Secret Service and is not open to the public; the Carters returned to Plains in 1981. The former President and First Lady Rosalynn Carter pursue many of the goals of his administration through the Carter Center in Atlanta, which has programs to alleviate human suffering and to promote human rights and world peace; when they are in Plains, Carter teaches Sunday school at Maranatha Baptist Church, open to the public. The former Plains High School, which both Jimmy and Rosalynn Carter attended, now serves as the park's visitor center and museum.
It features a classroom, principal's office, auditorium which have been restored to look as they would have when Jimmy Carter attended. An exact replica of the Resolute desk, which Jimmy Carter brought back to the Oval Office to use as his presidential desk, is exhibited, as is his 2002 Nobel Peace Prize. Other rooms feature exhibits that explain the lives of Jimmy and Rosalynn Carter, a short video focuses on the life of Jimmy Carter according to his friends and family; the farm in rural Archery where Jimmy lived from age four in 1928 until he left for college in 1941 has been restored to its appearance before electricity was installed in 1938. The former Plains Train Depot, where Carter headquartered his presidential campaign, now serves as a museum focusing on the 1976 Presidential Campaign and Election, it features exhibits. The train depot operated from 1888 until 1951, when all public transportation to and from the area ceased; the current home of the Carters, while not open to the public, is technically a part of the National Historic Site.
The Carters have lived in the home since 1961. During his presidency, it was used as his Summer White House.

James Edward Oglethorpe was a British soldier, Member of Parliament, philanthropist, as well as the founder of the colony of Georgia. As a social reformer, he hoped to resettle Britain's worthy poor in the New World focusing on those in debtors' prisons. James Oglethorpe was born in Surrey, the son of Sir Theophilus Oglethorpe of Westbrook Place and his wife Eleanor Lady Oglethorpe, he entered Corpus Christi College, Oxford in 1714, but in the same year left to join the army of Prince Eugene of Savoy. Through the recommendation of John Churchill, 1st Duke of Marlborough he became aide-de-camp to the prince, during the Austro-Turkish War of 1716–18 he served with distinction in the campaign against the Turks. After his return to England, he was elected Member of Parliament for Haslemere in 1722, he became a leading humanitarian, in 1728 he advocated reform of the terrible conditions experienced by sailors in the British Royal Navy by publishing an anonymous pamphlet,'The Sailors Advocate.' In 1728, three years before conceiving the Georgia colony, Oglethorpe chaired a Parliamentary committee on prison reform.
The committee documented horrendous abuses in three debtors' prisons. As a result of the committee's actions, many debtors were released from prison with no means of support. Oglethorpe viewed this as part of the larger problem of urbanisation, depleting the countryside of productive people and depositing them in cities London, where they became impoverished or resorted to criminal activity. To address this problem, Oglethorpe and a group of associates, many of whom served on the prison committee, petitioned in 1730 to form the Trustees for the Establishment of the Colony of Georgia in America; the petition was approved in 1732, the first ship, led by Oglethorpe, departed for the New World in November. Oglethorpe and the Trustees formulated a contractual, multi-tiered plan for the settlement of Georgia; the plan envisioned a system of "agrarian equality", designed to support and perpetuate an economy based on family farming, prevent social disintegration associated with unregulated urbanisation.
Land ownership was limited to fifty acres, a grant that included a town lot, a garden plot near town, a forty-five-acre farm. Self-supporting colonists were able to obtain larger grants, but such grants were structured in fifty-acre increments tied to the number of indentured servants supported by the grantee. Servants would receive a land grant of their own upon completing their term of service. No one was permitted to acquire additional land through inheritance. With Oglethorpe on that ship were cotton seeds provided by the Chelsea Medicinal Garden in London. Established by the Apothecaries' Company in 1673 for the cultivation and study of medicinal plants, the Garden's mission soon expanded to collect and study plants and trees from all over the world; the cotton seeds given to Oglethorpe were instrumental in establishing the cotton industry in the U. S. South; as discussed below, the plan for the colony was anti-slavery, emphasizing small family-owned farms. But economic pressures led to the lifting of the ban on slavery, as described below—and slavery was indispensable to the rise of large cotton-growing plantations throughout the Deep South.
Oglethorpe and the first colonists arrived at South Carolina on the ship Anne in late 1732, settled near the present site of Savannah, Georgia on 1 February 1733. He negotiated with the Yamacraw tribe for land, built a series of defensive forts, most notably Fort Frederica, of which substantial remains can still be visited, he returned to England and arranged to have slavery banned in Georgia after being moved by an intercepted letter from Ayuba Suleiman Diallo, a slave in Maryland. Oglethorpe and his fellow trustees were granted a royal charter for the Province of Georgia between the Savannah and Altamaha rivers on 9 June 1732. Georgia was a key contested area, it was Oglethorpe's idea that British debtors should be sent to Georgia. Although it is repeated that this would theoretically rid Britain of its so-called undesirable elements, in fact it was Britain's "worthy poor" whom Oglethorpe wanted in Georgia. Few debtors ended up in Georgia; the colonists included many Scots whose pioneering skills assisted the colony, many of Georgia's new settlers consisted of poor English tradesmen and artisans and religious refugees from Switzerland and Germany, as well as a number of Jewish refugees.
There were 150 Salzburger Protestants, expelled by edict from the Archbishopric of Salzburg in present-day Austria, established the settlement of Ebenezer near Savannah. The colony's charter provided for acceptance of all religions except Roman Catholicism; the ban on Roman Catholic settlers was based on the colony's proximity to the hostile settlements in Spanish Florida. On 21 February 1734, Oglethorpe established the first Masonic Lodge within the British Colony of Georgia. Now known as Solomon's Lodge No. 1, F. & A. M. it is the "Oldest Continuously Operating English Constituted Lodge of Freemasons in the Western Hemisphere". For a period in 1736, Oglethorpe's secretary was Charles Wesley well known as a hymnwriter of Met
Savannah is the oldest city in the U. S. is the county seat of Chatham County. Established in 1733 on the Savannah River, the city of Savannah became the British colonial capital of the Province of Georgia and the first state capital of Georgia. A strategic port city in the American Revolution and during the American Civil War, Savannah is today an industrial center and an important Atlantic seaport, it is Georgia's fifth-largest city, with a 2017 estimated population of 146,444. The Savannah metropolitan area, Georgia's third-largest, had an estimated population of 387,543 in 2017; each year Savannah attracts millions of visitors to its cobblestone streets and notable historic buildings: the birthplace of Juliette Gordon Low, the Georgia Historical Society, the Telfair Academy of Arts and Sciences, the First African Baptist Church, Temple Mickve Israel, the Central of Georgia Railway roundhouse complex. Savannah's downtown area, which includes the Savannah Historic District, the Savannah Victorian Historic District, 22 parklike squares, is one of the largest National Historic Landmark Districts in the United States.
Downtown Savannah retains the original town plan prescribed by founder James Oglethorpe. Savannah was the host city for the sailing competitions during the 1996 Summer Olympics held in Atlanta. On February 12, 1733, General James Oglethorpe and settlers from the ship Anne landed at Yamacraw Bluff and were greeted by Tomochichi, the Yamacraws, Indian traders John and Mary Musgrove. Mary Musgrove served as an interpreter; the city of Savannah was founded on that date, along with the colony of Georgia. In 1751, Savannah and the rest of Georgia became a Royal Colony and Savannah was made the colonial capital of Georgia. By the outbreak of the American Revolutionary War, Savannah had become the southernmost commercial port in the Thirteen Colonies. British troops took the city in 1778, the following year a combined force of American and French soldiers, including Haitians, failed to rout the British at the Siege of Savannah; the British did not leave the city until July 1782. In December 1804 the state legislature declared Milledgeville the new capital of Georgia.
Savannah, a prosperous seaport throughout the nineteenth century, was the Confederacy's sixth most populous city and the prime objective of General William T. Sherman's March to the Sea. Early on December 21, 1864, local authorities negotiated a peaceful surrender to save Savannah from destruction, Union troops marched into the city at dawn. Savannah was named for the Savannah River, which derives from variant names for the Shawnee, a Native American people who migrated to the river in the 1680s; the Shawnee destroyed another Native people, the Westo, occupied their lands at the head of the Savannah River's navigation on the fall line, near present-day Augusta. These Shawnee, whose Native name was Ša·wano·ki, were known by several local variants, including Shawano, Savano and Savannah. Another theory is that the name Savannah refers to the extensive marshlands surrounding the river for miles inland, is derived from the English term "savanna", a kind of tropical grassland, borrowed by the English from Spanish sabana and used in the Southern Colonies.
Still other theories suggest that the name Savannah originates from Algonquian terms meaning not only "southerners" but "salt". Savannah lies on the Savannah River 20 mi upriver from the Atlantic Ocean. According to the United States Census Bureau, the city has a total area of 108.7 square miles, of which 103.1 square miles is land and 5.6 square miles is water. Savannah is the largest port in the state of Georgia, it is located near the U. S. Intracoastal Waterway. Georgia's Ogeechee River flows toward the Atlantic Ocean some 16 miles south of downtown Savannah, forms the southern city limit. Savannah is prone to flooding, due to abundant rainfall, an elevation at just above sea level, the shape of the coastline, which poses a greater surge risk during hurricanes; the city uses five canals. In addition, several pumping stations have been built to help reduce the effects of flash flooding. Savannah's climate is classified as humid subtropical. In the Deep South, this is characterized by long and tropical summers and short, mild winters.
Savannah records few days of freezing temperatures each year. Due to its proximity to the Atlantic coast, Savannah experiences temperatures as extreme as those in Georgia's interior; the extreme temperatures have ranged from 105 °F, on July 20, 1986, down to 3 °F during the January 1985 Arctic outbreak. Seasonally, Savannah tends to have hot and humid summers with frequent thunderstorms that develop in the warm and tropical air masses, which are common. Although summers in Savannah are sunny, half of Savannah's annual precipitation falls during the months of June through September. Average dewpoints in summer range from 67.8 to 71.6 °F. Winters in Savannah are mild and sunny with average daily high temperatures close to 60 °F. November and December are the driest months re
