The first winter storm of the season moved into Central California on September 20. At least two inches of snow fell on Tioga Pass, and thunderstorms developed over the central and southern San Joaquin Valley, lingering into the late evening.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
