The thunderstorms produced moderate to heavy rainfall across portions of the San Joaquin Valley and Southern Sierra Nevada. There were numerous reports of flooding during the afternoon and evening of October 3 and Flash Flooding was reported near Kettleman City and Huron along the west side of the San Joaquin Valley. A Flash Flood Emergency was issued for the Ferguson Fire burn scar where there several reports of debris flows and roads being washed out. There were several reports of one to two inches of rainfall in the San Joaquin Valley and Southern Sierra Nevada from the October 3 thunderstorms. With a warm airmass prevailing over the area, snow levels were above 11000 feet and snowfall was confined to the higher peaks in the Southern Sierra Nevada. The low moved east of the region on October 4 bringing an end to the precipitation.
