Flood concerns are lingering in Texas, with more storms in the forecast.

At least 28 people have been killed in storms that began pummeling Texas and Oklahoma over Memorial Day weekend. Twenty-four of the deaths have been in Texas alone. A dozen people were still missing early Saturday.

Rivers and lakes around Houston, San Antonio and Dallas have all swelled. And forecasters are predicting more rain this weekend.

The Colorado River in Wharton and the Brazos and San Jacinto rivers near Houston are the main areas of concern as floodwaters move from North and Central Texas downstream toward the Gulf of Mexico.

Forecasters said the Colorado River at Wharton could crest on Saturday, causing major flooding in the community 60 miles southwest of Houston.

President Barack Obama has signed a disaster declaration for Texas after severe flooding this week.

The White House said Obama declared that he ordered federal aid to supplement other recovery efforts in the area affected by severe weather since May 4.

Texas Gov. Greg Abbott had earlier requested a presidential disaster declaration to get federal help for the counties affected.

Obama's action makes federal funding available to affected individuals in Harris, Hays, and Van Zandt counties.

Funding also is available to governments and some nonprofits on a cost-sharing basis for emergency work and repairs in Cooke, Gaines, Grimes, Harris, Hays, Navarro, and Van Zandt counties.
