.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 continues to surge offshore today. 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 bay. 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.
