 .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...
 
 Winds have stayed elevated east of the Mississippi River as a
 developing surface low moves across the coastal waters. This will
 have multiple impacts with Small Craft Advisory conditions expected
 Thursday into Friday. With the wind direction being primarily out of
 the east, minor coastal flooding is expected mainly for St. Bernard,
 eastern Orleans, southeastern St. Tammany parishes, as well as
 coastal Hancock and Harrison counties. 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.
