Cyclonic Storm Gulab and Severe Cyclonic Storm Shaheen were two tropical cyclones that caused considerable damage to South and West Asia during the 2021 North Indian Ocean cyclone season. Gulab impacted India and Pakistan, while Shaheen impacted Iran, Oman and the United Arab Emirates. Gulab was the third named storm of the 2021 North Indian Ocean cyclone season, as well as the fourth named storm of the season after its reformation in the Arabian Sea as Shaheen. The cyclone's origins can be traced back to a low-pressure area situated over the Bay of Bengal on September 24. The Pakistan Meteorological Department named this new cyclone Gulab.On September 26, Gulab made landfall in India's Andhra Pradesh but weakened overland, before degenerating into a remnant low on September 28. The system continued moving westward, emerging into the Arabian Sea on September 29, before regenerating into a depression early on September 30. Early on October 1, the system restrengthened into a Cyclonic Storm, which the IMD named Shaheen. The system gradually strengthened as it entered the Gulf of Oman. While slowly moving westward, the storm turned southwestward, subsequently making an extremely rare landfall in Oman on October 3, as a Category 1-equivalent cyclone. Shaheen then rapidly weakened, before dissipating the next day.

The 2021 North Indian Ocean cyclone season was an average season, the North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, peaking between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on April 2, when a depression designated as BOB 01 was formed in the north Andaman Sea and quickly made landfall in Myanmar. The basin remained quiet for over a month before Cyclone Tauktae formed. It rapidly intensified into an extremely severe cyclonic storm before making landfall in Gujarat, become the strongest storm ever to strike that state since the 1998 Gujarat cyclone. Later that month, BOB 02 formed and later strengthened into Cyclone Yaas. Yaas rapidly intensified into a very severe cyclonic storm before making landfall in northwestern Odisha. The season's strongest tropical cyclone was Cyclone Tauktae, with maximum wind speeds of 185 km/h (115 mph) and a minimum barometric pressure of 950 hPa (28.05 inHg).
