text:  All of southeast Texas is under a flood watch. Bradley Brokamp with the National Weather Service's Houston-Galveston office says residents should avoid unnecessary driving.

Local officials have issued voluntary evacuations for low-lying, flood-prone areas of the coast. I'm Dominic Anthony Walsh in Houston.
