EF1 tornado in Travis County, Texas

A NWS survey team concluded a tornado touched down on the west side of I-35 in Austin near Brownie Dr. and Diamondback Trl. The tornado peeled back a sheet metal roof to a business on the west side of the interstate and demolished a stone brick sign. The tornado also caused damage to roofing shingles, snapped large tree limbs and tossed a garbage dumpster at an apartment complex near Hardin Ct. The tornado moved east-northeast, crossing I-35, where it caused significant damage to the second floor of a storage facility. The metal roof and walls were collapsed in on the southwest side of the storage facility. Ten small moving trailers were lifted and tossed in various directions, with two tossed back across to the west side of I-35. Several power poles were blown over along the access roads of the interstate. The tornado continued east-northeast through the Windsor Hills subdivision, snapping numerous large tree limbs throughout the subdivision. Peak winds were estimated at 90-95 mph near the businesses along I-35.

An upper level shortwave trough moved around the longwave low over the Four Corners region. This upper distubance interacted with a surface boundary moving northward as a warm front from South Texas into a very moist airmass. This combination led to thunderstorms that produced heavy rain and isolated severe weather. A historic flash flood occurred on the Blanco River late Saturday night into Sunday. Hundreds of homes were destroyed along the river from the City of Blanco down into Wimberley and San Marcos. The flood wave continued downstream for days affecting residents and homes along the San Marcos and Guadalupe Rivers. Early estimates show damages in excess of 100 million dollars. Several people lost their lives due to flash flooding. A large tornado outbreak occurred this Saturday night producing numerous small brief tornadoes.
