 Brief Description: EVENT NARRATIVE: A supercell thunderstorm formed in the Mexican mountains west of Piedras Negras, across the Rio Grande from Eagle Pass. Reports from west of the Rio Grande indicate that a large and devastating tornado stuck Piedras Negras from the west, then dissipated on the west side of the Rio Grande. The supercell crossed the Rio Grande near 6:00 pm CST and struck the community of Rosita Valley near 6:01pm CST. Severe outflow winds from the storm estimated at between 80 mph and 100 mph struck the community first, causing minor damage to houses and mobile homes. Roofs were partially lifted, exteriors of homes were damaged, and trees were knocked over. Following the wind damage, hail to the size of golfballs struck the area, along with very heavy rain. Following the winds and hail, the tornado struck next. The team found the tornado touchdown point approximately one-quarter mile to the southwest of the Rosita Valley Elementary School. It struck a four room home??? destroying the outer walls and leaving only the interior walls standing. This damage was rated as EF-2 damage. The tornado then moved toward the east-northeast, directly toward the school. Along its path it damaged three more homes and destroyed a fourth. Damage to the three homes was rated EF-1 with the destroyed home rated EF-2. The tornado next struck a mobile home, tearing off its frame and tossing the debris into the school building. This also indicated EF-2 damage. Then the tornado crossed Rosita Valley Road, destroying mobile homes and damaging homes and tossing the debris into the south and west sides of the Rosita Valley Elementary School building. The initial strike points at the school showed only minor EF-0 damage. However damage was severe from the center of the school northeastward. It appeared that the tornadic winds were able to open enough of the center part of the roof to enter the interior of the school. These winds as well as winds that entered through wall openings caused severe damage to the north and south wings of the building. This damage indicated wind speeds approaching 140 mph and damage at EF-3 level. To the northwest of the school were two brick retail buildings; both were well-constructed. Outer walls were destroyed in each with damage to interior walls in one of the structures. This also suggested wind speeds near 140 mph and EF-3 level damage. Finally as the tornado exited the school area it struck an area of single family houses some 200 yards to the northeast. Most of the houses were swept off their foundations and many of them were completely flattened. This damage suggested wind speeds approaching 150 mph, the highest speeds found at Rosita Valley. This was mid-range EF-3 damage. In conclusion???the tornado was rated EF-3 on the Enhanced Fujita Scale with a path width near one-quarter mile and a path length near four miles. In all the tornado destroyed one elementary school, along with 59 manufactured homes and 57 houses. Major damage was reported to 21 manufactured homes and 19 houses with minor damage to10 manufactured homes, 22 houses, and 9 apartments. There were seven deaths in Rosita Valley as a result of the tornado. A family of five in one mobile home were killed as it was destroyed and rolled into the Rosita Valley Elementary School. Two other victims were found, one in a permanent home that had collapsed and one in another mobile home. EPISODE NARRATIVE: A supercell thunderstorm produced one of the strongest and deadliest tornadoes to strike near the Rio Grande in many decades.

 Brief Description: The most severe level of damage was located approximately 5 miles to the east of the Uvalde airport along Agape Road. This was due to a combination of both severe thunderstorm winds and a strong tornado. The wind damage, which had ended just south of Uvalde, once again was observed beginning just west of the Agape area by the team. The damage continued toward the east nearly one quarter mile to the Agape compound. Roof damage was noted at the first buildings, along with widespread damage to trees. Continuing to the east, the team found a mobile home that had been completely destroyed with the debris deposited about 30 yards to the south. This was the first time damage had been thrown in any direction except to the east and is believed to be just east of the starting point of the tornado. About 50 yards further to the east, an asphalt road was observed to have chunks of the topping removed and tossed toward the southeast. Very nearby, a large three-story concrete and steel-beam gymnasium valued at one million dollars had been gutted by the storm. The windward, west side was not blown inward as would have occurred with severe thunderstorm winds. Instead, it was pulled outward. A 40-foot steel beam had been bolted in a dozen different places to the building. The beam was pulled from the building and thrown back 15 feet to the northwest. Although many of the supporting steel beams held, several were pulled away and tossed. Concrete blocks, filled solid with concrete in their construction, had been ripped out of the building and lay tossed and strewn over the area. Much of the wall structure was destroyed. Pieces of sheet metal were strewn to the east and southeast for nearly one half mile. Additional damage to vegetation stretched for another 2 miles east of the gymnasium. Some of this damage was clearly due to severe thunderstorm winds and some of the damage was due to the tornado. Based on the level of damage of the mobile home and the gymnasium, the tornado was rated F2. The path width was estimated at 50 yards and the path length was estimated at 2 miles. From the reports available, it is thought the tornado developed about 1020 pm CST and dissipated around 1025 pm CST. It is the strongest tornado in South Central Texas since the evening of October 12, 2001, when an F3 tornado struck Stonewall, and an F2 tornado struck Hondo.
