 .SYNOPSIS...
 
 Winds will continue to increase across the local waters as an arctic
 cold front moves through this afternoon. Winds will gradually
 increase through the evening with strong, frequent gusts to Gale
 Force developing toward sunset, especially across the northeastern
 Florida coastal waters. Those winds will quickly increase seas
 tonight as well, with rough waves as high as 10 feet offshore and
 across the NE FL coastal waters. As winds turn northeasterly Monday,
 coastal troughing will develop encouraging scattered showers, mainly
 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.
