What the reports say
Written by National Weather Service staff at the time of the event · public domain
A line of thunderstorms formed along a cold front in central Texas and moved quickly southward. As the storms moved through Hays County, they produced a downburst that struck the town of San Marcos and spread southeastward into Caldwell County. An NWS Storm Survey Team reported numerous large tree limbs of diameter from 6 to 12 inches broken or blown over in San Marcos and along the I-35 corridor. Blown over trees and limbs were generally pointed toward a southeast direction. Many business signs and awnings were damaged along with roof damage to several businesses. Metal or tin roof in some businesses was peeled off on the side of the incoming high winds. Based on the damage and its pattern, it appeared that damage was the result of straight line winds indicative of a strong downburst estimated at 60 knots or greater. The strong winds also toppled over a semi truck. At Dudley Johnson Park the winds knocked over portable toilets and blew down numerous trees across the roads. Total damage in the town was estimated at $7 million.
Thunderstorms produced widespread large hail, accompanied by damaging winds that knocked down tree limbs, stripped leaves from trees and knocked out power and telephone communications to San Marcos for several hours. The hailstones broke windows in homes and school as well as Southwest State University.
A thunderstorm produced wind gusts measured at 70 mph that knocked over some trees in San Marcos. The City of San Marcos Office of Emergency Management reports near 750 thousand dollars in damages to public facilities, infrastructure, broadband tower repairs, and debris removal.
