.SYNOPSIS...
Northwesterly winds will quickly strengthen in the wake of a frontal
passage on Sunday with Small Craft Advisory conditions quickly
changing to Gale conditions Sunday afternoon. A Gale Warning is in
effect Sunday afternoon through Monday afternoon for frequent gusts
to Gale Force as low pressure rapidly strengthens near the Mid-
Atlantic and New England coasts through Monday night. Arctic high
pressure will then build along the northern Gulf coast on Tuesday
and then shift across the Florida peninsula on Tuesday night,
allowing for winds and seas to diminish across our local waters. The
high will move offshore by midweek ahead of another approaching cold
front that should impact our local waters late this week, with south
to southwesterly winds prevailing ahead of the front.
