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

Moderate easterly winds and medium seas will decrease through the
night as the gradient between high pressure over the Mid-Atlantic
and low pressure over the northwest Gulf lessens. A brief period
of light southerly winds will occur on Monday as the low pressure
system moves into the Texas coast. Moderate offshore winds are
expected to return later in the week as a weak cold front moves
into the Gulf.
