.SYNOPSIS...
A trough will gradually move west across the southern Gulf of
Mexico from early to mid week. Deep moisture will be associated
with this system that will bring widespread shower activity. The
gradient between the trough and high pressure to the northeast
will bring moderate to strong east to southeast winds at or above
20 knots going into tomorrow morning to afternoon that will
continue through mid week. This prolonged wind field will allow
for a significant increase in wave heights and swells. Small craft
advisories will likely be needed during this period. Also, tides
will be 1 to 2 feet above normal predicted levels that may lead to
coastal flooding.
