California weather is under the influence of a cold air mass that may bring freezes and frosts even as southern areas continue to see damaging winds.
The National Weather Service says a freeze warning will be in effect Friday night through Saturday morning in the central and southern San Joaquin Valley due to four to six hours of temperatures between 28 degrees and 32 degrees.
A frost advisory will be in effect for the Sacramento Valley and northern San Joaquin Valley, the Delta and the Mendocino coast.
A hard freeze warning is in effect for interior San Luis Obispo County valleys.
Meanwhile, high pressure in the Great Basin will produce gusty north and northeast winds in Southern California, where days of strong gusts have toppled trees and triggered power outages.
Protect Plants From Frost, Freeze
Freezing weather and frost can harm certain plants.
Greg Gayton, a California certified nursery professional with Green Acres Nursery and Supply in Sacramento, suggests covering plants with "frost protection cloth."
"We recommend frost protection cloth over plastic or burlap because you don't want to touch the foliage with the plastic,” said Gayton. But, the frost protection cloth can touch the foliage. Plastic will actually transmit cold to the foliage and actually cause more damage."
Gayton said frost protection cloth is available at nurseries and most "big box" stores.
He said tropical plants, ferns, citrus trees, jade, cactus and succulents are most at risk since they have lower tolerance for the colder temperatures.
