Synopsis for Baffin Bay to Rio Grande out 60 nm-
1000 AM 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 during the afternoon
hours across the Laguna Madre and 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.
