SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM

South to southeast winds will continue to increase and seas will
continue to build today with a tightening of the surface pressure
gradient. Caution flags and advisories will be required through the
overnight hours as a result. An approaching storm system this
evening will bring widespread rain with possible isolated
thunderstorms to the coastal waters. As this system departs late
on Sunday a lighter offshore wind will develop. As surface high
pressure departs later on Monday winds will become east to
by Tuesday as the next storm system and associated rains moves
across the area.
