Storm Tammy (2023): A Comprehensive Retrospective
1. Formation and Meteorological History
Storm Tammy formed from a tropical wave that departed the west coast of Africa in mid-October 2023. It gradually organized over the eastern tropical Atlantic, becoming a tropical depression on October 18. The system strengthened into Tropical Storm Tammy on October 19, and reached hurricane status on October 20. Tammy peaked as a Category 2 hurricane with maximum sustained winds of 110 mph (175 km/h) on October 21. It moved generally westward, then curved northward, impacting the Leeward Islands, Virgin Islands, and Puerto Rico. Tammy weakened to a tropical storm as it moved northeastward, eventually becoming post-tropical on October 26.
