.SYNOPSIS...
The axis of Atlantic ridging will remain positioned over the Florida
peninsula through midweek. A trough of low pressure will push
southeastward into the Georgia waters by late Tuesday, and will
then stall and weaken during the mid to late portions of next
week. This weather pattern will result in an offshore wind
pattern, with the Atlantic sea breeze developing during the early
to mid afternoon hours in the near shore waters each day.
