Tropical Storm Imelda has officially formed in the Atlantic, joining Hurricane Humberto, which has strengthened to a Category 5 storm. Forecasters are closely monitoring both storms as they develop, particularly with Imelda expected to impact the Southeastern U.S. and possibly the South Carolina coast with heavy rain and winds. There have been changes in the forecast paths for both storms, with models indicating that Imelda may stay farther east of Florida than initially predicted. Meanwhile, Tropical Depression Nine is also in the mix, posing potential threats to the Bahamas and the East Coast. The National Hurricane Center has issued tropical storm watches for parts of Florida as the situation evolves.
