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

Sea conditions should be improving as boundary moves inland and
winds diminish. Onshore flow develops today and will prevail
through the coming days. Ridging aloft and dry air moving into the
region will keep the forecast dry. Winds and seas do appear to
pickup once again later in the week when a pseudo cold front down
into coastal waters.

Advisory conditions will be possible as early as Thursday at
sunrise.
