...SMALL CRAFT ADVISORY IN EFFECT FROM LATE TONIGHT THROUGH FRIDAY AFTERNOON...
Synopsis: Onshore flow today will transition to offshore flow tonight as a cold front move into the Lower Texas coastal waters. Strong north winds and building seas will rapidly follow behind the cold front. Small craft advisories have been posted, and a few gale- force gusts are possible. A low- pressure system is expected to develop off the Lower Texas coast on Saturday and move quickly towards the Upper Texas coast by Saturday night, which will maintain the tight pressure gradient over the Gulf waters. Weak high pressure will yield much improved conditions Sunday and Monday.
