.Synopsis for Lower Atchafalaya River LA to High Island TX out
60 NM including Sabine and Calcasieu Lakes and Vermilion and Cote
Blanche Bays...
Showers are moving into the nearshore waters on an outflow
boundary from daytime convection.
Expect much of the same into Tuesday with an increase in daily
rainfall chances from Wednesday to the end of the week. This is in
response to a boundary moving down and settling into the north
Gulf region over the forecast period.
Winds will largely stay low, but Thursday and Friday may see a
period of increased winds and seas on pressure gradient when the
boundary dips into nearshore waters.
