A significant storm system exists, not over the Atlantic, but over Africa. It is specifically over the country of Nigeria.
Hurricane forecast models show a significant hurricane over the central Atlantic, in about 120 hours- that is 5 days. Besides the future "Danielle," we will be watching the northern parts of the Gulf of Mexico, for it will stay unsettled. All of the unsettled weather in the Gulf means plenty of rainy days ahead for Florida and Georgia.
Over the next 5 days portions of Florida's panhandle could get more than 6 inches of rain, with areas around Jacksonville getting around 3 inches of rain on average.
