What the reports say
Written by National Weather Service staff at the time of the event · public domain
Strong thunderstorms moving across California's Delta region resulted in damage from hail to crops and property. Motor vehicles were damaged, and the weight of the hail and the rain partially collapsed the roof of two commercial buildings in Stanislaus County.
A gustnado developed ahead of a line of showers moving through the city of Woodland. The discontinuous damage path was about 1700 feet long and 20 feet across. A tree two feet in diameter was uprooted, a section of metal bleachers were moved, and several tents were damaged. There was minor damage to three mobile homes in a nearby mobile home park, with porches pulled off and large flower pots knocked over.
A member of the public called to inform us about hail damage to their pistachio crop. They estimated that the hail stone sizes were generally around 0.75-1.0 inch stones but that they also varied greatly in size as it fell. After the hail ended they went to check on their pistachio crop and found out that they lost all of it. These trees were about 30 years old and sustained damaged.
