The National Weather Service has issued a winter storm warning and high wind advisory for Lake County, where rain showers are expected through Sunday.
Snow also is in the Lake County forecast for Sunday, when snow could fall as low as the 2,000 foot elevation mark.
The severity of the incoming storm has prompted the National Weather Service to issue a rare blizzard warning for the Sierras from Thursday through Saturday.
Pacific Gas and Electric Co. said itscrews are readying to respond to expected power outages.
The company reported that an initial wave of moderate to heavy rain and gusty winds is expected in the northern part of its service territory during the day Thursday, with more widespread rain and gusty conditions on Friday.
Low- and middle-elevation snow impacts are expected Saturday into Sunday, with several feet of snow above 5,000 feet and six-to-12-inches possible down to 2,000 feet, PG&E reported.
PG&E said it is pre-staging crews and materials and is prepared to use helicopters, snow cats and four-wheel drive to gain access to hard hit areas. However, the company said customers in remote areas should prepare for extended outages given the unique circumstances of this storm.
The company urged people to be prepared, including remembering not to touch downed wires, to use generators safely, use flashlights and not candles, have a backup phone, have fresh drinking water and ice on hand, secure outdoor furniture, turn off appliances and wait until after the storm has passed to conduct clean up.
