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

Changes since last update: Added Small Craft Advisory for GMZ575 and
577 in effect through noon Monday. Exercise caution for all waters
expect MS sound and Lake Pontchartrain/Maurepas from Noon Monday
through 9PM Monday night.

New: Small Craft Advisory in effect for all waters 9PM Monday
through 3PM Tuesday.

Tonight, a recent frontal passage has introduced gusty wind at
around 18-22kts from the NE, which will persist overnight into
Monday morning ahead of the next developing surface low over the
western Gulf. As this low drifts northeast, it`ll cross gulf waters
providing a round of heavy rain and thunderstorms primarily from
Monday afternoon through early Tuesday morning. In any one storm,
waterspouts, winds <34kts and locally higher waves/seas can be
expected. As this low passes, confidence on how strong winds will
remain outside of thunderstorms remains in question. There is now
exercise caution headlines as the low passes, but could be upgraded
to advisory if conditions warrant. Then, as the low passes early
Tuesday to the NE, strong NW winds will increase across waters at
around 15-20kts, with the 2nd round of Advisory headlines in effect.
Waves/seas will respond reaching around 5-7ft in this time frame
mainly for Gulf waters, 3-5ft for protected waters. High pressure
builds into the region mid-week, with winds and waves/seas calming
down, but still expecting another system to impact the region
Thursday and Friday, with increasing winds and shower/thunderstorm
activity expected.
