South Texas worked to dry out on Friday after severe thunderstorms a day earlier flooded streets, forced the closure of an airport, and compelled dozens of water rescues, as many drivers were forced to abandon their vehicles on roads and parking lots as some areas were inundated with more than a foo t of rain. Texas Department of Agriculture Commissioner Sid Miller said Friday that parts of the Rio Grande Valley received half of their annual rainfall in just 48 hours. “This is a devastating tragedy for our Valley community,” said Miller. “Texas is no stranger to natural disasters, but it’s important that Texans stand behind the Rio Grande Valley right now. While rain was desperately needed, the sheer volume that has fallen in this region has caused severe harm. The rain also fell downstream of the Rio Grande River and is unlikely to replenish water levels in Falcon Reservoir, where relief is still urgently needed.” Miller’s office said the hardest-hit areas include the counties of Cameron, Hidalgo, Starr, and Willacy. “Rising floodwaters forced road closures and created hazardous conditions, endangering lives while disrupting businesses, schools, and agricultural operations. With river levels expected to rise further, the situation remains dangerous,” Miller’s office said. TxDOT crews are monitoring roads throughout the night.

Flores told KRGV in Weslaco they were being inundated with water. “We’re just getting like a bucket of water poured on us and it’s too much for the drainage system,” said Flores. “A lot of these are stranded motorists with no immediate danger, but we do want to make sure we are prioritizing the medical calls first.” Flores said Alamo’s fire and police departments had responded to more than 50 water rescues on Thursday. Weslaco Mayor Adrian Gonzalez said his city was inundated with about 14 inches of rain, prompting 30 to 40 water rescues of stranded motorists and residents trapped in their homes by rising floodwaters. “It’s a historic rainstorm and it’s affecting all the Valley, not just Weslaco. It’s just so much water in a short period of time,” Gonzalez told reporters at a news conference. Flooding in the Rio Grande Valley, Texas, March 28, 2025.

Palmview, located west of McAllen, received more than 18 inches of rain over the past two days. In neighboring Cameron County, officials asked Gov. Greg Abbott to declare a disaster for the county after more than 17 inches of rain caused significant flooding. “The rainfall amounts we received have been record-setting, and not in a good way. All county resources are being utilized right now, and we are assisting in all ways possible,” Cameron County Judge Eddie Treviño, Jr., the county’s top elected official, said in a Facebook post. Valley International Airport in Harlingen was closed on Friday and all flights were canceled due to area flooding. “We are working tirelessly to reopen and focused on ensuring safety,” airport officials said in a statement. Flooding in the Rio Grande Valley, Texas, March 28, 2025. More than 3,700 in several counties in South Texas remained without power on Friday afternoon, according to AEP Texas. A flood warning was still in effect for portions of South Texas, including Cameron, Hidalgo and Willacy counties, through early Friday afternoon, according to the National Weather Service. “There’s a break from the rain this morning, which will allow flood waters to gradually recede, but we’ll still need to keep an eye on the development of isolated showers and thunderstorms once again this afternoon,” the National Weather Service said on social media. “Any additional rainfall will be quick to cause flooding issues given the heavy rainfall that has already fallen.” The Pharr-San Juan-Alamo school district opened two shelter locations on Thursday night for residents. One shelter had been opened in Weslaco. More than 20 South Texas school districts and college campuses canceled classes on Friday due to the severe weather and flooding.
