.Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote
Blanche Bays...

A robust cold front moves is surging offshore today. While it is
not anticipated for storms to be an issue, winds will quickly
increase with sustained north winds over 20-25 knots and frequent
gusts of 35 knots. A Gale Warning was issued for the coastal
waters and a small craft advisory was issued for the inland lakes
and bays. Waves will build in response to the winds, building
between 6 and 10 feet today and Monday. Winds will start to
ease on Monday night, falling below 20 knots by Tuesday morning.

A low water advisory is in effect through this afternoon as gusty
north winds push waters offshore in combination with low tide
cycle. It is possible waters will briefly fall toward 1 ft below
MLLW Monday morning, but an advisory is less likely with easing
winds.

The pressure gradient tightens Tuesday into Wednesday as a high
pressure system moves off to the east. As a result, we could see
elevated onshore flow and the potential for marine fog.
