EF1 tornado in Cameron County, Texas

A rapidly-developing mini-supercell formed ahead of an approaching squall line near the Lower Texas coast just before 4 AM Saturday, May 13. The supercell spawned a quick spin-up tornado that struck the town of Laguna Heights, Texas, over a two-minute period before the circulation moved over Laguna Madre Bay and rapidly dissipated. The tornado tracked to the east-northeast after the circulation was impacted by the approaching squall line, creating a boomerang effect since the original motion of the radar couplet was to the north-northwest prior to touchdown. Winds may have reached 110 mph, the top of the EF1 scale, in a few locations ' but the very poor quality of construction suggests 105 mph is a better estimate.

The strongest portion of the tornado, rated EF1, flattened at least six poorly built mobile home structures, removed part of the second story of a local business, and removed the majority of roof decking on at least ten other residences and buildings. At least a half dozen ash and mesquite trees were snapped or uprooted and two wooden power poles were bent. Casualties were found in several of the demolished mobile homes. A man in his forties was killed when the home collapsed on him. Five others were injured in the same cluster of damaged homes, and two more were injured in a flattened mobile home near the shoreline of Laguna Madre Bay. Two of the injuries, in the home along the bayfront, required extended hospitalizations. Thirty-eight additional residents were displaced by the tornado and were housed at the local events center with American Red Cross assistance. In all, there was the one fatality and eleven injuries, of which two were critical head injuries. Surrounding the EF1 area, portions of roofs and shingles were removed from residences, large limbs were broken, and fences were knocked down.
