Pre-Dawn Microburst Sweeps Hidalgo to Harlingen
Event: Las Cañas Neighborhood/Moorefield Road. The combination of a pulse microburst striking a number of very poorly constructed homes led to the destruction of 20 mainly trailer-type residences, near the intersection of Monte Cristo (Farm to Market Road 1925) and Farm to Market (FM) 681. In a number of cases, the residences were completely demolished; a total of 13 persons required transport to local hospitals. Thankfully, by mid afternoon on the 16th, all were releases. While the majority of injuries were minor, in one instance, a 3 year old girl had to be rescued from a pile of rubble that was once an unanchored trailer home. In addition to the building damage, at least eight wooden telephone poles were pulled down. The damage track continued to the east southeast, generally along an north of FM 1925, at least to the intersection of FM 1925 and Federal Highway 281, twelve miles away. The vast majority of damage beyond the Las Cañas neighborhood was hundreds of downed limbs from mesquite trees. Based on assessment from an NWS survey team, peak winds were between 65 and 70 mph, with the highest values likely where the telephone poles were pulled down, and again in the mesquite stand about two miles east. A map shows the track and path. Red dots are neighborhoods; green dots are areas of tree damage. Santa Rosa to Harlingen. Across the County Line in Cameron, known damage began again in Santa Rosa, where a pickup truck was flipped over on a driveway near the intersection of Orphanage and Louisiana; a number of power lines were also down in the area. As the radar indicated velocity further increased, so did notable damage, this time in northeast Harlingen, culminating with an 86 mph wind gust which blew portions of three hangar roofs off. Pieces from one of these roofs, made of heavier asphalt underlines, knocked out at least two large windows in the control tower! In a nearby neighborhood, generally well constructed buildings fared well; however, dozens of large tree limbs were snapped. The table below shows preliminary statistics from the surveys conducted on May 16th. A host of Photographs were taken by NWS and local emergency management officials. Check back here for updates.
