A small cluster of thunderstorms developed over eastern Nuevo Le��n State, Mexico, during the   mid-evening of April 24th and sped north northeast across the Rio Grande River and over the Rio Grande Valley. The initial cell evolved into a straight line wind event as it crossed the river slamming the Lower Rio Grande Valley National Wildlife Refuge in Santa Ana. In only fifteen minutes, structural, tree, and powerline/power pole damage piled up from Alamo to Mercedes, extending north to pockets in Edinburg, Elsa, and Edcouch. The heaviest damage was noted in Donna and Weslaco, where a National Weather Service survey, joined by Emergency Management from Weslaco/Donna/Mercedes, Elsa/Edcouch, and Hidalgo County, determined peak winds ranged from 65 to 75 mph, with pockets of 80 mph speeds based on the type of damage, exposure, and construction. A second core of strong winds ripped through southwest Cameron County, with unknown tree damage in the Santa Maria/Los Indios area that continued northeast into the Harlingen/Primera area before exiting near Rio Hondo. Damage estimates are expected to surpass $500 thousand.
