Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
343 PM EST Fri Feb 8 2019

.SYNOPSIS...
A cold front will cross our local waters late this afternoon and
early this evening. Northerly winds will strengthen in the wake of
the front this evening and will become north-northeasterly after
midnight, with Small Craft Advisory conditions overspreading our
local waters before sunrise on Saturday. Strong high pressure
currently centered over the Plains states will build into the Ohio
Valley on Saturday afternoon and will reach the Mid-Atlantic coast
by late Saturday night. Northeasterly winds will continue to
strengthen on Saturday, with frequent Gale Force wind gusts
expected during the afternoon and evening hours. High pressure
will then weaken as it shifts offshore of the Mid-Atlantic coast
on Sunday afternoon, allowing for gradually decreasing east-
northeasterly winds. A warm front will then lift northward across
the northeast Florida waters on Sunday night and the Georgia 
waters early on Monday, resulting in prevailing southerly winds 
early in the week. The next cold front will then cross our area on
Tuesday night.
