Tropical Storm Erika Batters Caribbean; Florida, Bahamas on Alert
Should Erika strengthen rapidly, the system could curve along or east of the Atlantic coast of Florida.
How soon Erika makes more of a turn to the northwest and then to the north will determine the extent of impacts in the Bahamas and Florida. If the system survives as far north as Florida, there will be concerns farther north into the Southern states, especially in the Carolinas and perhaps as far west as Louisiana.
There is also the chance the system stalls along the Southeast U.S. coast after negotiating Florida waters.
Which scenario unfolds will depend on the strength of an area of high pressure set to build over the western Atlantic Ocean late this week and into the weekend. This high is the reason for the cooler air pouring into the Northeast late this week.
