2008: Half Moon Bay had a low temperature of 33.
Strong northwest winds fanned an early season wildfire in the Santa Cruz Mountains.
The blaze, called the "Summit Fire," began at 5:30 am on the 22nd and went on to burn 4,270 acres over the next few days, ultimately destroying 31 buildings and injuring 16 people.

Heavy rain from thunderstorms was produced by a very cold and unstable storm from the north.
Several debris flows occurred.
In the Santiago burn area of eastern Orange County, extensive damage was done to homes and businesses.
In rural northeast Moreno Valley, 28 residences were flooded and damaged.
Minor damage occurred in the Witch Creek burn area around Ramona.
Snowfall of several inches hit the mountains, even as low as 5000 feet elevation.
Thunderstorms deposited several inches of hail from Redlands to Perris.
Several reports of nickel size hail in Moreno Valley and dime size hail in Murrieta.
Snowplows were called to clear the hail.
Awnings, trees and vehicles were damaged.
Four tornadoes touched down near Moreno Valley.
One tornado was rated EF-2, which was the strongest California tornado since the Sunnyvale tornado in 1998, and was on the ground for an exceptional 21 minutes.
Nine railroad cars were derailed.
A semi truck was lifted 30-40 feet in the air and severely injured the driver.
