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

Cutoff upper level low is still centered just northeast of the local
area. A surface low is underneath that upper low over northern MS
with frontal boundary now well into the eastern Gulf. Thus, westerly
winds in most coastal waters to persist through mid week as the low
shifts east and surface ridge center slides across the center of the
Gulf. Once that high pressure reaches the eastern Gulf, should start
to see more onshore flow to resume and persist. Wind speeds
throughout the forecast period will vary but generally be around 10
to 15 knots with short term periods of 15 to 20 knots.
