Thunderstorms hit both Yucca Valley and Phelan, and produced an F0 tornado in Phelan. The thunderstorms produced severe flash flooding that damaged homes in Spring Valley Lake (Victorville) and Hesperia. Vehicles were trapped in five feet of water. Water eight feet deep inundated a railroad causing major delays (a train backup extending to Cajon Pass). The tornado caused little damage, but damages from flash flooding exceeded $5 million.
