California deep freeze continues; farmers hard hit - latimes.com
Temperatures on Saturday night were expected to dip as low as 25 degrees, triggering freeze warnings across Southern California.
"It's not unusual for us to get these cold snaps this time of year, but it's one of the colder ones we've had in awhile," said Curt Kaplan, a meteorologist with the National Weather Service's Oxnard office.
But a cold snap can change that in hours. In January 2007, citrus growers lost 60% of the state's crop to freezes. In 1998 it was 85%. The worst season in memory was the Christmas freeze of December 1990, when a week of temperatures in the teens defoliated the orchards, leading to a total loss for that season and the one after, Nelsen said.
