Monday will be much closer to normal (for September) as northeasterly winds will be gusty along the beach (up to 20 mph) and clouds and possibly sunrise rains/downpours along the coast will be present. These rains will spread inland quickly. Although, not a washout, there will be showers and storms on Exact Track 4D throughout the day. Highs will only be in the 80s.

Tuesday through Saturday we will really see the September rains move across the area, but primarily along the beaches of Georgia and North Florida. The pattern shifts so much that inland conditions will actually dry out as the northeasterly winds concentrate the rains at the beach. Afternoon highs only in the 80s.

Tropics will become much more active starting Monday, but really active by late in the week.
