|Brief Description: The strongest of the Friday night tornadoes struck the town of Stonewall. This tornado, rated F3 on the Fujita Scale, was preceded by brief gusty winds of 30 to 40 miles per hour, very heavy rainfall and spotty .5-inch hail. The tornado formed around 830 pm CST near the intersection of Hahn Road and SH290. It moved north-northeastward for .75 miles, crossing SH290 and the Pedernales River. Just north of the river, it made a slight turn toward the east, now moving another mile toward the northeast. It crossed North River Road and continued over open country until it crossed Ranch Road 1623. After passing RR1623 for approximately .25 miles, it dissipated. The worst damage, F3 level, was to trees and homes between RR1623 and SH290, across the northwest and north central part of Stonewall. Ninety homes sustained damage with 6 destroyed. In addition, 7 mobile homes were destroyed and 20 damaged. Damage was also reported to 22 buildings. A two-story home had the entire second story destroyed, and a concrete building lost most of its walls and all of its roof. Other damage along the path typically included destroyed and damaged roofs and walls of homes and businesses as well as widespread damage to trees. The tornado path was approximately .25 miles in width and 2.5 miles in length. Although the tornado was not seen due to the late hour and darkness, residents did report that after heavy rain and hail, the wind became calm, and it was followed by a "roaring sound" so often reported in tornadoes. Five persons were injured with one man hospitalized as a result of the tornado.|

|Brief Description: Tornado number five, strongest of the six and rated as a minimal F2 tornado on the Fujita Scale, formed about 3.5 miles southwest of the intersection of Loop 1604 and I35. It struck near 720 pm along near Silver Street and Bravo Street and moved toward the north for 1.5 miles. It apparently weakened periodically, producing a hit-and-miss damage path. It completely destroyed four mobile homes and damaged several others.|

|Brief Description: The tornado was spotted as it touched down near 940 pm CST just northwest of the Hondo airport. It grew to nearly 500 yards in width and moved toward the southeast for 1.2 miles across the airport and over the National Guard Armory before dissipating near the center of town. Although much of the damage was F0 and F1 on the Fujita Scale, the tornado was rated F2 because of the level of damage from the airport to the armory. During this time it destroyed a large hangar, partially destroyed the roof and walls of the concrete Armory and moved numerous mobile homes off their pads. One mobile home clearly showed the nature of damage from a tornado. The center of the mobile home was completely destroyed, along with a tree in front of it, while much less damage was indicted on both ends of the mobile home as well as vegetation near the ends. The storm also knocked out power to much of the area, and this, along with the darkness in the late night hour, made spotting very difficult. It is possible that additional small tornadoes might have accompanied the storm, but the combination of damage from the large tornado and the downburst winds, along with the darkness of the late night hour made it impossible to tell. Almost 150 homes in Hondo and almost 50 more outside the city were damaged, with nearly 100 mobile homes damaged. At least 10 houses and 30 mobile homes were destroyed. Losses to homes and mobile homes were estimated at 1.5 million dollars. In addition, nearly two dozen aircraft, including one corporate jet and 14 crop dusters, were damaged and destroyed at the Hondo Airport. Some were in collapsed hangars while others were lifted, tossed and set down across the Airport area. Commercial losses placed at 18 million dollars. At least 25 persons were injured.|

|Brief Description: The tornado was preceded by strong, gusty winds, very heavy rainfall and finally, large hail. Severe winds in advance of the tornado took a roof off the High School in Harper and laid it on the ground on the opposite side of the building. These winds also damaged several other roofs in the area. The tornado began its track around three miles east of Harper, moving toward the southeast. It lifted post oak trees out of the ground with their roots in tact. Approximately 2 miles down the path, it turned toward the south and continued for another 1.5 miles. Along its track, it destroyed. 35 homes, 10 mobile homes, and damaged or destroyed 25 outbuildings and barns. The tornado damage several vehicles and tossed one jeep over 100 yards.|
