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

The calm conditions of the past several days will rapidly
deteriorate this evening and into tomorrow morning as a robust
cold front moves offshore. While it is not anticipated for storms
to be an issue, winds will quickly increase with sustained north
winds over 20 knots and frequent gusts of 35 knots. A Gale Watch
was issued for the outer coastal waters and a small craft advisory
was issued for the inland lakes and bay along with the nearshore
waters. Waves will build in response to the winds, building
between 6 and 10 feet Sunday and Monday. Winds will start to
subside on Monday night, falling below 20 knots by Tuesday
morning.

Low water advisories may be needed on Monday as the north wind
pushes waters offshore but it is too early to decide on one way or
the other.

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.
