It is just a slow system. Only moving 10 miles an hour. Florida is going to be dealing with it for at least another week.
What concerns me is what other storm system comes AFTER all this flooding from a tropical storm. It won't have to dump much rain to flood with the ground being so saturated in low lying areas - and with more wind, that could really be a problem.
There is another low pressure area developing.
Here is the radar. You can see Fay, and the area circled in yellow is the low pressure which could be our next storm.
