Potential 1st tropical storm of the season threatens Texas with flash flooding

The potential first tropical storm of the season is expected to bring heavy rain and dangerous flooding to Texas this week.

The tropical system could strengthen to Tropical Storm Alberto on Tuesday or Wednesday before making landfall in Mexico, just south of Texas.

The storm is forecast to bring flash flooding from Houston to Corpus Christi to San Antonio.

Five to 10 inches of rain is expected and winds could top 40 mph.

In Galveston Bay, Texas, the storm surge might reach 2 to 4 feet.

A tropical storm warning is in effect along the Texas coast from Port O'Connor to the mouth of the Rio Grande.

Tornadoes are also possible.

"People are going to have to be smart, look out for their neighbors, look out for their families. And don't drive in high water," Houston Mayor John Whitmire said Monday.

Atlantic hurricane season lasts from June 1 to Nov. 30.
