.SYNOPSIS...

A small Craft Advisory was issued for the outer marine zones due
to slightly elevated winds. Winds will drive a favorable NE'ly
fetch to build seas over 6ft for southern portions of the 20-60nm
offshore zones, particularly south of Sabine Pass. Rain chances
will be elevated from the middle of the week onward as a low
pressure center moves up the Texas coastline and a warm front
moves north through the GoM.
