The National Weather Service has issued a Winter Storm Warning for the Sierra Nevada through 4 PM Friday.
This Warning period will cover a pair of winter storms.
The snow levels will begin around 2,000 to 3,000 feet tonight, then rise during the day Wednesday to around 6,000 to 8,000 feet.
The snow levels will drop again Thursday night through Friday to as low as 2,500 to 3,000 feet.
Total snow accumulations will range from one to seven feet above the 5,000 foot elevation.
Winds could gust as high as seventy mph above the 9,000 foot elevation.
Additionally, a Flood Watch is in effect for the Sierra Nevada, the Mother Lode and the Northern San Joaquin Valley from late tonight through Thursday afternoon.
The total rainfall amounts in the Central Valley from the storms will range from one to four inches. Three to six inches of rain is expected in the Mother Lode and the lower elevations of the Sierra Nevada.
The rain on top of the 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 the Northern San Joaquin Valley from 4 AM Wednesday until 4 PM Thursday.
The strongest winds are expected during the daytime hours both days.
Winds of twenty to thirty mph are expected with gusts ranging from forty to fifty 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.
