The National Weather Service has issued a Winter Storm Warning for the Sierra Nevada through 4 PM Friday.
Additional snow accumulations will range from one to six feet above the 5,000 foot elevation.
Wind gusts from fifty to seventy mph are likely above the 9,000 foot elevation.
Additionally, a Flood Watch remains in effect for the Sierra Nevada, the Mother Lode and the Northern San Joaquin Valley through Thursday afternoon.
The total rainfall amounts in the Central Valley from the storms will range from one to two inches.
Three to seven inches of rain is expected in the Mother Lode and the lower elevations of the Sierra Nevada.
The rain on top of the existing snow, will create flooding concerns for elevations below 5,000 feet.
Rivers and streams will rise on Wednesday as rain increases through the day. Street flooding and mudslides are also possible in the Mother Lode.
Finally, a Wind Advisory is in effect for both the Mother Lode and the Northern San Joaquin Valley until 1 PM this afternoon. Another Wind Advisory has been issued for Thursday from 6 AM to 6 PM.
Winds of twenty to thirty mph will continue with gusts ranging from forty to fifty-five mph.
A Wind Advisory means that wind gusts of 40 mph are expected. Winds this strong can make driving difficult, especially for small cars and high profile vehicles. Use extra caution.
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 Winter Storm Warning for snow 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.
