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.
