SAN ANTONIO -- Some South Padre beaches are closed until further notice because of Hurricane Isaac.
The National Weather Service in Brownsville said the risk of high tides and strong rip currents will continue through Wednesday. The agency said long period swells could increase waves to head height or more. Four to six feet waves are possible. In addition, some tidal run up to the sand dunes was possible, which might curtail driving on the beaches Wednesday.
