(TEXAS) — At least three people have died after heavy rain brought record-breaking flooding to South Texas, according to officials.
The deaths occurred in Hidalgo County, where officials issued a disaster declaration as a result of the flooding. The county, which includes the city of McAllen, saw some of the heaviest rain accumulations over the last 24 hours.
There was no further information about the three deaths immediately available, but officials said they would release more details later.
A large part of South Texas is still reeling from the life-threatening flooding that began overnight and continued into Friday morning.
Thunderstorms began Wednesday, with another round of heavy rainfall on Thursday afternoon and evening. The rain continued through Friday afternoon.
The National Weather Service issued flash flooding emergency warnings multiple times on Thursday and overnight for South McAllen and Harlingen — both located in the Rio Grande Valley in the southernmost parts of Texas.
“This is a particularly dangerous situation,” the NWS said in a statement issued Thursday night, urging people to avoid travel unless fleeing a region subject to flooding or are under an evacuation order.
The region received between 6 inches and a foot of rain or more in some areas, according to the NWS. McAllen got more than 6 inches of rain, while more than 14 inches was recorded at the Valley International Airport in Harlingen.
The NWS received reports for several vehicles stranded on Interstate 2 in waist-deep water, according to the agency. Dozens of water rescues took place as a result of the flash flooding.
Video shows first responders in inflatable boats rescuing people stranded on roadways. The South Texas Health System hospital in McAllen experienced minor flooding on its first floor.
Several school districts in the region canceled classes on Friday, as did the South Texas College in McAllen.
Flooding continued into Friday morning, with rivers nearly overflowing. A flood watch is in effect for parts of South Texas and southern Louisiana.
Water levels at the Arroyo Colorado River at Harlingen are nearing a record-breaking 30 feet. There is no precedent for the kind of damage a 30-foot water level in the Arroyo Colorado River could do, according to the NWS. The previous record water levels measured at the Arroyo Colorado River was 24 feet.
The flooding stemmed from a stationary boundary — a front between warm and cold air masses that moves very slowly or not at all. A band of significantly heavy storms was forming over the same hard-hit areas on Friday morning. A storm with 3-inch rain rates was forming over Harlingen on Friday morning.
The system also conjured up a tornado, with a twister reported near Edcouch, Texas, about 25 miles northeast of McAllen, that damaged several structures.
The potential for showers and thunderstorms in this region is expected to continue through the afternoon, with the threat ending Friday evening, forecasts show.
