.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
A weak area of low pressure will gradually drift east across the
Louisiana Coast on Thursday. This will tighten the pressure gradient
especially east of the Mississippi River delta. Winds will increase
with moderate to strong east-southeast to easterly winds. This will
have multiple impacts with Small Craft Advisory conditions expected
Thursday into Friday. Winds will relax and return to offshore late
Friday and then more variable on Saturday with the passage of
another weak sfc low. A frontal passage on Sunday night will bring
another push of strong offshore winds on Monday which could prompt
small craft headlines for much of the coastal waters.
