.SYNOPSIS...Favorable marine conditions will continue along the
Lower Texas Coast through a majority of the period courtesy of
surface high pressure over the western Gulf of Mexico. Light to
moderate onshore flow and low to moderate seas will persist for
the next couple of days. Marine conditions may become a bit more
adverse towards the end of the forecast due to an organizing
tropical system in the Gulf of Mexico.
