Episode Narrative On Thursday afternoon, August 25th 2011, portions of the Coastal Bend of South Texas experienced strong to severe thunderstorms. Several clusters of thunderstorms moved southwest across the Coastal Bend and produced winds between 40 and 70 mph. Isolated pockets of wind damage were the result. There was also a brief EF-0 tornado which touched down near Alamo Beach.
An upper level disturbance originating from Northeast Texas and Arkansas the day before had pushed into Southeast Texas by the morning of the 25th. This disturbance then moved southwestward into South Texas during the afternoon of the 25th. Meanwhile, the atmosphere across South Texas became increasingly moist and unstable throughout the afternoon as this disturbance moved into the area.
Damage was fairly minimal throughout the region, although 3,000 customers did lose power during the storms. The storms did bring beneficial rainfall to parts of drought-stricken South Texas.
Event Narrative An NWS survey concluded a short lived tornado touched down near Alamo Beach Street and Lee Street in Alamo Beach. Near this point two homes were observed with small portions of their roofs peeled back. Sheet metal was also torn off the side of one of the homes and a window was broken. A third home near the area was observed to have missing shingles. The tornado continued west to a point near F. M. 2717 between Fannin and East Sunrise Streets. At this point, a poorly constructed mobile home with two floors was observed to have significant damage. The top floor was taken off and deposited to the west-southwest. The bottom floor was partially shifted off the blocks but remained upright. A brick facade on the west side of the home collapsed. Maximum winds were estimated to be around 75 mph with a path length of one quarter of a mile and path width of 100 yards.
