Synopsis for Baffin Bay to Rio Grande out 60 nm-
355 PM CDT Mon Aug 19 2019

.SYNOPSIS...High pressure ridge gradually heads northwest over the next
couple of days, weakening the pressure gradient, and allowing
winds to generally decrease across the lower Texas coastal waters
through the week. Gusty winds are possible through early this
evening on the Laguna Madre and on the nearshore Gulf waters
through Tuesday. Seas slowly subside through Wednesday and build
late Thursday into Friday due to increasing southeasterly swell.
Deep tropical moisture flowing northward will increase coverage
and perhaps intensity of showers and thunderstorms especially in
the Gulf beginning on Wednesday.
