EF0 tornado in Hidalgo County, Texas

A small tornado briefly touched down about 1.5

miles east of Edcouch, lifting the sheet metal roof of a warehouse

belonging to a crop dusting company. Pieces of the roof were

blown to the northeast along the 0.25 mile path, landing in open

fields on the north and south side of SH-107. The debris was

scattered in varying directions along the path. Partial metal wall

failure was also noted to the building, which was a total loss. A

metal building structure (MBS) hangar that sheltered one of the

crop-dusting aircraft was also damaged, with a small portion of

the roof lifted off and the garage door bent inward, toward the

center of the circulation. The aircraft inside was also impacted,

with an estimated $500 thousand in damage to it. Each structure

was old with generally poor connectors and rusted metal parts,

each built more than 80 years ago, according to the owner.

Other damage included parts of an unanchored fence blown down at

a drive-through convenience store, several large mesquite limbs

snapped off in open areas along the track, one rotting and unused

telephone pole snapped, and another one bent.

A resident of a manufactured home who witnessed the event noted a

swirling column of rain as the tornado passed by, indicating that

the tornado was likely rain-wrapped.

Several rounds of showers and thunderstorms pummeled the Lower Rio Grande Valley, especially during the afternoon and overnight hours of March 27th into early on March 28th, resulting in historic seasonal rainfall and widespread flash and areal flooding across the RGV. Total rainfall ranged from 8 to nearly 19 inches based on trusted observations, with 10 inches or more falling across some of the highest populated locations from south McAllen through the south side of Interstate Highway 2 in Hidalgo County, then farther north in Cameron County, where 12 to nearly 19 inches fell between La Feria and Rio Hondo, including Harlingen and San Benito. Trusted radar estimates indicated up to 20.5 inches in east Harlingen, but as of this writing there were no verified values this high from trusted observers.

Initial rainfall began late on March 26th in eastern and southern Cameron County, with flooding in east Brownsville toward Port Isabel around sunrise on the 27th.

Nearly five thousand homes and other structures were impacted, with more than two thousand having major damage or destruction due to 2 or more feet of water in them. Hundreds of local roads were flooded with up to 4 feet of water in some places, and at least one thousand vehicles trapped on flooded roads were damaged or totaled. Unfortunately, there were fatalities, with five dead on the U.S. side of the Rio Grande due to drowning and a lightning-induced fire, and one on the Mexican side of the border in Reynosa.

In addition to the flooding, wind damage occurred in several locations, with two small tornadoes touching down during the late afternoon of the 27th near Edcouch, and just after midnight on the 28th in Port Isabel.

Though damage estimates were still unknown as of late May, it is estimated that total damage was upwards of $100 million. By early July, damage estimates had risen to $157 million; these numbers only included initial values of Public Assistance (PA) of $94 million, and $63 million in Individual Assistance in much of the Rio Grande Valley. These values did not include privately-insured damage, and totals were likely to exceed $200 million. Additional damage estimates will be available by the end of 2025.
