Introduction
The Rio Grande Valley experienced unprecedented rainfall this week, as severe thunderstorms rolled through the region, leaving residents grappling with flooding and property damage. Meteorologists have reported record-breaking rainfall totals, and local authorities are responding with emergency measures.
Record Rainfall
On Thursday, March 26, 2025, the National Weather Service (NWS) noted that cities across the Valley, including McAllen, Harlingen, and Brownsville, recorded rainfall levels that broke historical records. McAllen reported a staggering 4.96 inches, surpassing its previous record set in 1999. Brownsville witnessed 5.3 inches, breaking a record established more than a century ago in 1911. In Harlingen, 3.72 inches of rain fell, surpassing records that had stood since 1923.
Meteorologist Holley Kamba indicated that much of the rainfall occurred between 1 and 4 p.m., with some locations, such as Port Isabel and Laguna Heights, receiving nearly 7 inches before early Thursday morning. This deluge led to widespread reports of flooding across the area.

Emergency Services
The Hidalgo County government has delayed its office openings until 10 a.m. on Friday, while the South Texas Health System reported minor flooding on its McAllen campus.
