Severe Thunderstorms and Flash Floods Impact Rio Grande Valley, Texas
Late Thursday into Friday, an onslaught of intense thunderstorms wreaked havoc across the Rio Grande Valley, resulting in substantial flash flooding throughout multiple Texas counties. Authorities have issued stern warnings urging residents to steer clear of low-lying areas as the storms continue to unleash heavy rainfall.
Flash Flooding Wreaks Havoc
In Hidalgo County, the city of Alamo experienced a dramatic response from fire officials, confirming over 50 water rescues on Thursday alone, as reported by KRGV. Among the rescues, Fire Chief RC Flores mentioned that an emergency vehicle struggled to reach a pregnant woman in distress near a Walmart. Thankfully, a fire truck eventually managed to navigate the flooded streets and provide assistance.
The situation remained dire throughout the night, as the Hidalgo County Sheriff’s Office cited, “a lot is happening because of the thunderstorm,” anticipating continued heavy rainfall into Friday.
Neighboring Counties Also Struck
Cameron County was not spared, with officials from the National Weather Service confirming similar water rescues amidst the severe weather. Residents were strongly advised to seek higher ground to avoid the life-threatening consequences of flash floods.
Violent Weather Conditions
These storms have the potential to yield a multitude of hazardous conditions, including large hail, gusty and damaging wind gusts, brief tornadoes, and torrential rainfall. Coastal areas are also facing a high risk of dangerous rip currents, posing threats even to proficient swimmers.
Extended Warnings
The weather service has issued several flash flood warnings and a flood watch warning that extended overnight into Cameron, Hidalgo, Starr, and Willacy counties. Areas impacted have experienced rainfall totals between 6 and 10 inches, with an additional 1 inch expected.
The Risk of Flooding
Forecasters have emphasized that slow-moving storms combined with saturated soils could result in excessive runoff, leading to critical flooding in rivers, creeks, streams, and urban areas that frequently experience drainage issues. The National Weather Service has issued critical safety advisories, urging people to “stay away or be swept away.” They noted that “river banks and culverts can become unstable and unsafe” and warned that most flood-related fatalities occur within vehicles.
Impact on Local Healthcare Facilities
In a concerning turn, South Texas Health System’s hospital in McAllen reported minor flooding on its first floor due to stormwater drain issues. A viral video showcased water forcefully bursting through a wall, leading to ankle-deep flooding in a hospital corridor. As a precaution, walk-in and ambulance patients were temporarily diverted to other medical facilities, and visitation hours were paused.
However, an update from the hospital confirmed that they have partially reopened their Level 1 Trauma Center and are now accepting stroke and trauma patients.
Despite resuming some normal operations, ambulance patients with emergencies other than stroke and trauma are still directed to local hospitals, and visitation remains closed until further notice.
School Closures Announced
The severe weather prompted numerous temporary school closures across Hidalgo and Cameron counties. Institutions like South Texas ISD campuses, South Texas College, the University of Texas Rio Grande Valley, IDEA Public Schools, Triumph Public High Schools, and the Brownsville Independent School District announced cancellations for Thursday due to the dangerous conditions.
As the situation progresses, residents are urged to remain vigilant, monitor weather updates, and adhere to safety advice. With forecasts predicting ongoing adverse weather, taking precautions is paramount.
