Lower Texas coastal waters from Baffin Bay to the mouth of the

.SYNOPSIS...The tightened pressure gradient resultant from the
interaction between high pressure over the western Gulf and the
low pressure over the Sierra Madre will produce moderate winds and
low to moderate seas tonight. The high will move to the central
Gulf during the weekend as the low pressure will remain over the
Sierra Madre. This will lead to building seas and winds becoming
stronger during the afternoons over the Laguna Madre. Small Craft
Advisories are likely starting tomorrow and could continue for the
next several days over all waters for Monday and Tuesday.
