.SYNOPSIS...

A stalled front will extend across the Georgia waters will gradually
shift southward late tonight into Wednesday as high pressure wedges

off of the Florida coast by late this week. This pattern will bring
shift prevailing south to southwest flow towards more onshore mid to
late week. The National Hurricane Center is monitoring an area of
potential tropical cyclone off the Southeast coast later this week
that may organize and shift westward towards the coast this weekend.
Continue to monitor NHC forecasts through the week.
