Thunderstorm Wind in Cameron County, Texas

Just after 1000 AM CDT May 9, 2026, a strong microburst descended in central Cameron County from a small but potent line of thunderstorms and produced damage along a west-northwest to east-southeast oriented line starting from Harlingen, TX through Laureles, TX. Overall damage was observed to traffic lights, several homes, powerlines, poles, fences, crops, and trees. At least a dozen homes had

various degrees of damage. The worst damage was to a poorly constructed

single wide type structure in Green Valley Farms, where two persons were injured, including an elderly woman who sought shelter underneath the structure and had broken ribs. Another trailer-style residence on Country Boy Road, east of Green Valley Farms, had its roof ripped off, and debris fell onto a teenaged resident's head, requiring hospitalization.

At least five more recreational vehicles/mobile homes - with wheels and unanchored - were damaged. Hundreds of medium to large tree limbs were blown

down. Several signs including one billboard and two restaurant signs were blown down along the track. Power poles and lines were blown down in the same direction (west-northwest to east-southeast). The NWS Damage Survey reported an estimated path length of nearly 13 miles, and an average path width of 2 miles. Detailed notable wind damage reports from the damage survey were as follows:

*1011 AM CDT: Partial roof removal from a greenhouse at Lowe's, and a leaning power pole on the property (east Harlingen)...estimated wind 69 mph.

*1019 AM CDT: Old wooden billboard blown off its pole at intersection of US Highway 77 business and the frontage road. Wind speed estimated at 75 mph. 2.3 miles south-southeast of San Benito.

Wind speed estimated at approximately 75-80 feet AGL (24 meters)

*1021 AM CDT: Poorly constructed roof was ripped off and ended up collapsing, then part ended up behind the structure. Young resident (16 year old girl) was struck by falling debris and injured, requiring hospitalization. 4 miles east-southeast of downtown San Benito (just east of Green Valley Farms)...estimated wind 70 mph.

*1024 AM CDT: Poorly built and unanchored older single wide trailer style home blown away from location and demolished. In background, much of another single-wide was destroyed after roof was ripped off. Eighteen persons were in the structures; two were injured. One elderly woman had broken ribs after sheltering under the home; another had unknown lesser injuries. Several had minor cuts and bruises. Poor construction and full exposure to the wind, commensurate with nearby damage, suggested 75-80 mph wind in Green Valley Farms (4 miles east-southeast of San Benito)

*1025 AM CDT: Very poorly affixed roof was partially ripped off a single-wide, with rusted sheet metal. Wind speed estimated to be close to 70-75 mph per nearby damage (4.5 miles east-southeast of San Benito).

*1026 AM CDT: A dozen wooden telephone poles snapped, likely due to a domino effect. Medium to large limbs of every tree at residence near intersection of Adams and San Jose Road were damaged. Speed here was likely 80 mph (among highest of surveyed area). 4.4 miles east of San Benito.

*1030 AM CDT: Uprooted large and old tree, snapped near the base (uprooted). Many other large limbs down in the neighborhood in west Laureles. Estimated wind speed was 80 mph.

*1033 AM CDT: Damage to mobile home/RV, downed powerlines, and damage to nearby trees on east side of Laureles. Wind speed estimated at 75 mph at this location.

Final damages are unknown, but based on survey results, $500,000 is a fair assessment as of this writing.

Friday night into Saturday, May 8-9, 2026, strong to severe thunderstorms in association with atmospheric disturbances initially developed across Zapata County on the 8th, before redeveloping as a single severe thunderstorm that waxed and waned between Starr and Cameron County on May 9th. Large hail was initially reported in Starr County just after daybreak on the 9th, before the storm re-strengthened in Hidalgo and Cameron County by mid-morning. The episode culminated into a microburst that caused structural damage to roofs, traffic lights, fences, homes, trailers, and power poles as well as trees in central Cameron County. There were 3 injuries, two requiring hospitalization, where poorly constructed mobile-type homes were destroyed.

At least 45,000 customers were without power at peak or just after the storms crossed the populated IH-2 corridor from near McAllen to east of Harlingen, one of the more widespread outages in recent memory.
