1997 Central Texas tornado outbreak


A deadly tornado outbreak occurred in Central Texas during the afternoon hours of May 27, 1997 in conjunction with a southwestward moving storm complex. The complex produced 20 total tornadoes, mainly along the Interstate 35 corridor from northeast of Waco to north of San Antonio. The outbreak was particularly noteworthy for spawning the Jarrell tornado, one of the fiercest and most destructive F5 tornadoes ever recorded.
At its peak, the Jarrell tornado was three quarters of a mile wide and tracked across the ground for, inflicting catastrophic damage in northwestern parts of Jarrell while killing 27 people. All 27 deaths caused by the tornado occurred within one subdivision of Jarrell – a neighborhood of 38 well-built houses called Double Creek Estates. Each residence was completely dismantled, swept away, and reduced to a concrete slab, while trees in the area were completely shredded and debarked, and grassy fields were scoured to a depth of. Many tornado researchers, after reviewing aerial damage photographs of Double Creek Estates, considered the Jarrell storm to be the most violent tornado they had ever seen in terms of damage intensity.
In addition to the Jarrell tornado, the outbreak produced an F4 tornado near Lake Travis and three F3 tornadoes – including one which moved through Cedar Park.

Meteorological synopsis

In the early morning hours of May 27, a large mesoscale convective complex developed over eastern Oklahoma and western Arkansas. A "gravity wave" or outflow boundary was generated by this system and stalled out over Central Texas. This was oriented from the northeast to the southwest, causing the supercells and subsequent tornadoes to move from the northeast toward the southwest, which is exceptionally unusual. Also unusual on this day was the low wind shear and extreme atmospheric instability.

F3Cedar ParkWilliamson, Travis2105 – 2115This tornado moved south through Cedar Park before crossing into Travis County and lifting just northeast of Mansfield Dam. A historic train was struck, with a coal tender converted to hold diesel fuel being flipped over and thrown a short distance. The north wall of an Albertsons grocery store was pushed inward slightly, along with large metal doors. Another grocery store had much of its roof torn off, and several other businesses sustained varying degrees of roof and structural damage. Over 100 homes were either damaged or destroyed, with some sustaining significant roof loss and severe structural damage. A pickup truck was tossed into the front wall of one house. Many trees were downed along the path, especially in Travis County. Fifteen people were injured in Cedar Park.
F1NW of Four PointsTravis2115 – 2115Brief tornado with minimal damage.
F4W of LakewayTravis2150 – ?1 death – The tornado touched down near the shore of Lake Travis, destroying a marina and most of the watercraft at the docks. Numerous structures sustained varying degrees of damage as the tornado moved westward and later southwestward, including a Southwest Bell telephone building that was destroyed and a home across the road which had several collapsed walls. The telephone building was well constructed, which warranted an F4 rating. Further southwest, a steel tower carrying high transmission power lines was destroyed. More site-built homes, mobile homes, and other buildings were either heavily damaged or completely destroyed, leaving many uninhabitable. Many trees were downed along the path. Five people were injured.

Jarrell, Texas

The Jarrell tornado originally touched down at 3:40 p.m. CDT as a rope-like tornado near the Bell-Williamson County line. By 3:45 p.m., the tornado had quickly intensified into a violent wide multiple-vortex tornado. It scoured a cotton field down to a depth of as it moved southwestward toward the west side of Jarrell.
Moving very slowly as a large wedge tornado, the tornado entered the northwestern portion of Jarrell at around 3:48 pm CDT and struck the Double Creek Estates neighborhood. Catastrophic damage occurred here, with the tornado completely destroying all 38 houses and killing 27 people in the subdivision. Many of the homes in the tornado's path were well-constructed and bolted to their foundations, but the tornado left only slab foundations. The debris from the destroyed homes was either thrown several miles away or dismantled into small fragments and scattered for long distances across the countryside. Several entire families from Double Creek Estates were killed in the tornado, including all five members of the Igo family and all four members of the Moehring family. The tornado victims sustained such extreme physical trauma that recovery teams had difficulty distinguishing human remains from animal remains scattered throughout the area. Many of the human remains were never recovered at all. Additionally, about 300 cattle were killed by the storm.

A later assessment from NOAA noted:
"In the Double Creek area, approximately 40 structures were totally destroyed. One of the most striking signs in approaching this area was the distinct lack of debris of any size. Closer inspection showed lots of little debris, but no sign of large items. At least half a dozen cars were identified from the air lying in the open areas, most of them flattened and encrusted with mud and grass. Later, a ground survey revealed that most of the debris that was left in the area was extremely small, indicating the power of the tornadic winds."

The tornado slowly tracked toward the southwest, which is an exceptionally uncommon movement pattern for tornadoes in North America, then eventually entered a wooded area before dissipating. The tornado produced some of the most extreme ground scouring ever documented, as the earth at and around the Double Creek Estates was scoured out to depths of 18-24 inches, reducing lush fields of grass to vast expanses of mud. When the tornado crossed county roads outside of Jarrell, it tore away 500-foot segments of asphalt from the roads and chipped pieces of concrete out of their respective slabs. The tornado also picked up large amounts of loose soil as it deeply scoured the ground, producing a sandblasting effect on nearby houses and their occupants. In addition to the 27 deaths in Double Creek Estates, one person was seriously injured and less than a dozen people suffered minor injuries after the tornado. The tornado left no damage indicators with which to judge higher winds, but video of the tornado shows extremely violent rotation and updraft winds comparable to other F5 tornadoes. Newspaper articles from 1997 reported wind speeds from 400-500 mph.
The tornado moved further southwest into a heavily wooded area of cedar trees before rapidly dissipating at 3:53 p.m. CDT, just to the southwest of Jarrell. The tornado lasted 13 minutes, travelling only during its lifespan.
There were 27 fatalities, all in the Double Creek Estates neighborhood. Today, the neighborhood has been rebuilt, and Jarrell Memorial Park was constructed on the site of the Igo family home to honor the victims.

Overpass traffic jam

Numerous vehicles sought shelter underneath various overpasses as the Jarrell tornado formed and strengthened, turning Interstate 35 into a virtual parking lot. Texas Highway Patrol worsened the traffic jam by stopping both northbound and southbound traffic in anticipation of the tornado moving southeastward and crossing the highway. The tornado moved parallel to Interstate 35 for nearly its entire lifespan in a south-southwestward direction, a very rare occurrence.
