The Winter Storm Warning for the Sierra Nevada above 5,500 feet, will remain in effect until 4 AM Friday.

Additionally, a Blizzard Warning has been issued for the Sierra Nevada above 6,500 feet, from 7 PM tonight until noon on Thursday.

Total snow accumulations above the 7,000 foot elevation, will range between two to six feet.

Winds gusting to as high as eighty-five mph will cause blizzard/whiteout conditions. This could also cause extensive tree damage.

Travel will be dangerous to nearly impossible, and is strongly discouraged.

A High Wind Warning for both the Mother Lode and the Northern San Joaquin Valley remains in effect until noon on Thursday.

Winds of twenty-five to thirty-five mph will continue in the Mother Lode, with gusts ranging between fifty to sixty-five mph.

Winds of twenty-five to thirty-five mph will continue in the Central Valley, with gusts ranging from forty-five to sixty mph.

Some of the probable impacts will include power outages, downed trees and difficult driving conditions.

Also, a Flood Watch remains in effect for both the Mother Lode and the Northern San Joaquin Valley through Thursday morning.

Rainfall amounts of one to two inches is possible in the Central Valley. Two to four inches of rain is forecast for the Mother Lode.

Periods of heavy rain, along with the strong winds, will make driving difficult.

There is the potential for some localized ponding of water on roadways. Rises on small streams and creeks could lead to flooding.

Finally, a Flash Flood Watch has been issued for the Sierra Nevada through Thursday evening.

Heavy rain may lead to excessive runoff, rising water levels on area rivers and present the threat of flash flooding.

Mud slides, rock slides and debris flows are possible in some locations, especially in the vicinity of the Ferguson burn scar.

Some roads may become closed, impassable, or washed out.

A Winter Storm Warning means there will be snow covered roads and limited visibilities. Travel is not recommended while the Warning is in effect. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency.

A Blizzard Warning means severe winter weather conditions are expected or occurring. Falling and blowing snow with strong winds and poor visibilities are likely. This will lead to whiteout conditions, making travel extremely dangerous. Do not travel. If you must travel, have a winter survival kit with you. If you get stranded, stay with your vehicle.

A High Wind Warning means a hazardous high wind event is expected or occurring. Sustained wind speeds of at least 40 mph or gusts of 58 mph or more can lead to property damage.

A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION. You should monitor National Weather Forecasts and be prepared to move to a safe location should Flash Flood Warnings be issued. If you live in a flood prone area, this would be a good time to review an emergency escape plan in the event high water or a debris flow threatens your home.
