Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1035 PM EST Fri Feb 28 2020

SYNOPSIS
High pressure currently centered over the western
Gulf of Mexico will gradually move into the eastern Gulf by
Saturday evening, continuing eastward across North Florida on
Sunday, then on to near Bermuda by late Monday. Low pressure will
start to develop in the far western Gulf and across eastern Texas
on Tuesday, causing southeast breezes to freshen and become
occasionally strong. A brief lull is expected Wednesday night in
advance of a cold front. Winds quickly freshen once again
Thursday in the wake of the next frontal passage.
