A Dallas-area Red Cross shelter and two in East Texas have opened for possible Hurricane Isaac evacuees, however, the San Antonio and Houston chapters have not opened shelters as of Wednesday morning.

Volunteers with the American Red Cross were ready Tuesday at a shelter at Faith Baptist Church in DeSoto. American Red Cross spokeswoman Anita Foster says shelters also have been set up at St. Louis Baptist Church in Tyler and Williams Memorial United Methodist Church in Texarkana, Texas. Each shelter can accommodate about 150 people.

Meanwhile, Cameron County officials closed the South Texas county's Padre Island and Boca Chica beaches Tuesday evening because of dangerous tides and currents.
