Tropical Storm Mindy was a short-lived tropical storm which affected much of Mexico and the Southeastern United States in September 2021. The thirteenth tropical storm of the 2021 Atlantic hurricane season, Mindy originated from a tropical wave which entered the Atlantic Ocean from the west coast of Africa on August 22. The wave traveled westward across the Atlantic, breaking apart for the first time on August 27. After moving through Central America breaking apart once more on September 2. The northern part of the wave moved into the Gulf of Mexico on September 5, moving gradually northward between two mid-level ridges. On September 8, the wave began showing signs of organization and gale-force winds, becoming Tropical Storm Mindy southwest of Apalachicola, Florida. Mindy intensified before landfall, attaining a peak intensity with maximum sustained winds of 60 mph (97 km/h) and a minimum barometric pressure of 1,000 mbar (30 inHg) at 01:15 UTC on September 9; as the cyclone made landfall on St. Vincent Island, Florida. The storm rapidly weakened inland before entering the Atlantic and being absorbed by a baroclinic system on September 11.

Hurricane Olaf was a Category 2 Pacific hurricane that struck the Baja California Peninsula in September 2021. The fifteenth named storm and sixth hurricane of the 2021 Pacific hurricane season, the cyclone formed from an area of low pressure that developed off the southwestern coast of Mexico on September 5, 2021. The disturbance developed within a favorable environment, acquiring more convection and a closed surface circulation. The disturbance developed into Tropical Depression Fifteen-E by 18:00 UTC on September 7. The depression strengthened into a tropical storm and was named Olaf at 12:00 UTC the next day. Olaf quickly strengthened as it moved to the north-northwest, and was upgraded to a hurricane 24 hours after being named. Hurricane Olaf continued to intensify and reached peak intensity while its center was just offshore the southwestern coast of Baja California Sur, with maximum sustained winds of 105 mph (169 km/h) and a minimum barometric pressure of 975 mbar (28.8 inHg). Just after reaching peak intensity, the hurricane made landfall near San José del Cabo. Interaction with the mountainous terrain of the Baja California Peninsula caused Olaf to quickly weaken. It was downgraded to a tropical storm at 12:00 UTC on September 10. The system became devoid of convection later that day and degenerated to a remnant low by 06:00 UTC on September 11.
