2007-04-21 · near Tulia, Swisher, Texas

Event narrative

A strong tornado delivered a crippling impact on the local economy of Tulia, Texas, when it devastated industrial and residential sections of the small community of 5,000 residents around 19:00 CST on the 21st. A two block wide swath of damage paralleled U.S. Highway 87 in west Tulia for fifteen blocks. Three persons were treated at area hospitals for injuries, almost thirty homes sustained damage or were destroyed along with twenty businesses, and approximately five hundred people were displaced or made homeless.

Local officials and newspaper accounts indicated that several of the businesses that were heavily damaged during the tornado served as staples to the Tulia economy prior to the storm. U.S. President George W. Bush declared Swisher County a federal disaster area on May 1, 2007.

This destructive tornado developed near a power plant at the intersection of Broadway Street and U.S. Highway 87 in west Tulia at 18:57 CST. The tornado moved north and caused extensive damage to a local supermarket at the intersection of U.S. Highway 87 and

Sixth Street. A large portion of the roof was removed on the east side of the structure, and one exterior wall collapsed inward. Smaller sections of two additional exterior walls additionally collapsed.

A local auto dealership, located near the supermarket, also sustained a large amount of structural and inventory damage. Forty-one vehicles were damaged by flying debris, and a motor home on the property was overturned. A large overhead door on the east side of the structure's show room failed, resulting in the failure of the west wall. A large storage container was blown into the southwest corner of the building and caused the partial collapse of the roof.

Several large metal industrial-style buildings sustained major damage due to the failure of large overhead doors and buckling of roof purlins on the south side of the buildings. One such structure collapsed onto a collection of classic cars, and resulted in a $250,000 loss.

Two storm chasers escaped injuries when they were struck by the tornado along the industrial stretch of U.S. Highway 87. Their vehicle was blown into a brick building, and then a tractor-trailer was blown broadside against the chase vehicle.

Damage also was observed to the north and northeast of the industrial area, with severe damage in residential areas including a mobile home community between Eighth and Ninth Streets just west of Highland Elementary School. Five mobile homes were damaged, with two others completely destroyed.

The most significant residential damage occurred in a subdivision along Northwest Ninth Street through Northwest Eleventh Street. Across this area, a number of homes suffered roof losses. Roofs were totally removed from at least two single-family homes on Tenth Street near Airport Road, with partial exterior wall collapses also noted.

The tornado dissipated near the Tulia Municipal Airport at 19:01 CST.

Meteorologists from the National Weather Service in Lubbock, Texas, Texas Tech University, and engineers from numerous private and governmental agencies surveyed the Tulia damage. All indications suggest that the maximum winds with the Tulia tornado were between 125 and 135 mph. This makes the Tulia tornado an EF-2 tornado on the Enhanced Fujita scale for tornado intensity. The total economic loss is estimated at $2.0 million.

Wider weather episode

An outbreak of severe weather impacted much of the central U.S. from Minnesota to Texas during the late afternoon and evening hours of the 21st. The west Texas South Plains and the extreme southern Texas Panhandle were affected by a series of significant tornadoes. At least five tornadoes were spawned by a single cyclic supercell thunderstorm that resulted in more than $3.5 million in damages.

The most severely impacted communities included Olton (Lamb County) and Tulia (Swisher County). Both of these west Texas towns were impacted by EF-2 tornadoes that destroyed property and injured four people, and more than 14,000 customers were without electrical power throughout the night.

The tornado outbreak was caused by a potent storm system that progressed east over the Four Corners region of the western U.S. on the 21st. A potent upper level jet stream spread over the Southern Plains of the U.S., and helped to create a favorable environment for supercell thunderstorms and tornadoes along a dryline that was stretched across west Texas.
