What the reports say
Written by National Weather Service staff at the time of the event · public domain
A thunderstorm produced four inch diameter hail in Round Rock. This storm was part of a complex that caused 700 million dollars in hail damage in Texas. The damage in Austin, Georgetown, and Round Rock was the most impactful from this system and totaled upwards of 600 million dollars in damage across Williamson and Travis counties. Thus 300 million dollars of damage is being listed on this Williamson County entry. An article from the Austin American Statesman tells that Round Rock school district estimated losses of 70 million in damages to 62 facilities.
Western Williamson County escaped the very large hail, reporting only small hail and moderate wind gusts. Hail grew to baseball-size in the eastern part of the county where high winds also knocked over trees near Thrall. Widespread crop damage was also reported with the storms.
Roofs were blown off houses as well as the main building of the High School in Hutto. Classes had to be cancelled for the following day. Several barns were flattened, trees were blown over and power lines were destroyed north of Hutto. A high school football game, already underway, was cancelled as the storm approached, and all persons evacuated into the school. This quick action no doubt prevented numerous injuries.
