Additionally, a Winter Storm Watch has been issued for the Sierra Nevada from late Thursday night through Saturday morning.

Finally a Flash Flood Watch has been issued for the lower Sierra Nevada from Friday morning through Friday evening.
One to two inches of rainfall is expected over the Sierra foothills. The combination of already wet soils and moderate to heavy rain could lead to excessive runoff. Flooding of small streams and low water crossings will be possible.
A Winter Weather Advisory means that periods of snow and gusty winds will cause travel difficulties. Be prepared for slippery roads and limited visibilities, and use caution while driving.
A Winter Storm Watch means there is a potential for significant snow, sleet, or ice accumulations that may impact travel.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should be prepared to take action should Flash Flood Warnings be issued.
