.SYNOPSIS...

A weak cold front will move south of the waters today, and then
dissipate. A stronger cold front will move into the area waters on
Tuesday, followed by strengthening northeast winds in the wake of
this frontal passage, creating Small Craft Advisory conditions from
late Tuesday night through at least Thursday morning throughout our
local waters. Breezy onshore winds and elevated seas are expected
through Thursday night as high pressure gradually weakens over the
southeastern states. Otherwise, additional rounds of thunderstorms
are forecast today through Tuesday evening with heavy rainfall and
gusty winds expected at times.
