It was a sight for sore eyes in San Antonio as much-needed rainfall swept through the region on Wednesday and Thursday. However, the heaviest downpours fell just south of the Alamo City, triggering severe flooding across South Texas.

Many shelters across the Rio Grande Valley opened up Thursday, offering refuge from the storm. The hardest-hit areas in Texas include Cameron, Hidalgo, Starr, and Willacy counties. Rising floodwaters have forced road closures, creating hazardous conditions that endanger lives and disrupt businesses, schools, and agricultural operations.

North Texas is sending relief to victims of historic and deadly flooding along the Rio Grande. Major Frankie Zuniga with the salvation army in McAllen says hundreds of residents were displaced from their homes due to the flooding. More help is on the way as a team of volunteers from Texans on Mission left North Texas on Tuesday morning.
