.SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...

Light to moderate easterly flow can be expected Wednesday as high
pressure remains centered to the north. Cautionary headlines are out
for portions of the local waters through late this afternoon. By
late Thursday, the high will shift eastward and a warm front will
retreat northward, resulting in winds turning more southeasterly.
This will also mark an increase in showers and thunderstorms across
the coastal waters. Shower and thunderstorm activity will increase
further Friday and Saturday as another cold front drops toward the
coast. Depending on where the front eventually stalls, at least
scattered shower and thunderstorm activity could persist into next
week.
