On August 29, 2020, an area of low pressure formed south of Central America. The system moved very slowly as it gained a closed circulation. On August 31, the NHC named the system Tropical Storm Iselle. Late on September 1, Iselle peaked as a Pacific storm with winds of 65 mph and a pressure of 996 millibars. Iselle then weakened to a Tropical Depression while crossing over central America on September 2, before entering the Atlantic on September 3 while still a depression. On September 5, Iselle entered rapid deepening, becoming a Category 3 hurricane 24 hours after being a tropical storm. Iselle peaked with 125 winds and slowly moved northward.
