 .SYNOPSIS...
 
 Breezy northwesterly winds will shift more towards the north to
 northeast throughout the morning hours behind a cold front that has
 moved through. Frequent gusts to gale force are expected over all
 waters with a Gale Warning in effect. Rough waves will be expected
 as well, as high as 10 feet offshore and across the NE FL coastal
 waters, as well as breakers up to 7-8 feet in the surf zone south of
 Duval County with a High Surf Advisory in effect through the
 afternoon. Coastal troughing will develop overnight which will
 increase cloud cover as well as isolated to scattered shower
 chances, especially further offshore. Weakening high pressure will
 then shift southward Tuesday, allowing winds and seas to subside.
 High pressure then shifts offshore on Wednesday afternoon in advance
 of a weakening frontal boundary that will likely cross the Georgia
 waters on Friday morning and may then stall over the northeast
 Florida waters by Friday night.
