A line of strong thunderstorms had stuck Crystal City near 1240 pm CST. Although individual storms were moving toward the northeast, the line appeared to be moving to the southeast. The downburst winds were all discharged toward the southwest, as all damage around Crystal City area was blown in that direction. Damage was severe in Crystal City. Leaves had been shredded from trees and plastered onto the sides of the cars and houses, and streets were covered with the shredded leaves. Homes had damage to their outside walls, roofs, and windows. What was shocking was to see the piles of semi-melted hail still as high as 2 feet in some of the drifts created by the flooding. In spite of the fact that the hail had been melting for over 24 hours when the survey was made, it was still piled in spotty waves across the city from east to west and north to south. Hail was reported to have been as large as 1.5 to 2 inches in diameter, with a couple of reports of hail to 3 inches. The high winds, combined with hail and rain, caused widespread damage to homes, destroying two mobile homes and the roofs of two houses. Several dozen homes in Crystal City sustained some type of damage. Some of the worst damage occurred at the library and the H.E.B. grocery store. The metal roof was blown off the library and deposited on the southwest side of the building. The roof of the H.E.B. grocery store collapsed. It appeared to be beneath the area where the air conditioners were positioned on the west side of the store. This is also where the rain and ice would have accumulated the thickest and would possibly have clogged drainage holes. One injury was reported in the storms.
