The Winter Storm Warning issued for Yosemite National Park (above the Valley floor) and the Winter Weather Advisory issued for the western slope of the northern Sierra Nevada will both remain in effect until 10 AM this (Friday) morning.
Heavy, wet snow continues to fall, starting between 7,000 to 7,500 feet.
The total snow accumulations above the 7,000 foot elevation, will range from three inches to a foot-and-a-half. The higher you go, the more the snow.
Winds continue to gust as high as forty to fifty mph.
Roads, and especially bridges and overpasses, will likely become slick and hazardous. Travel could be very difficult.
If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.
Persons should delay all travel if possible. If travel is absolutely necessary, drive with extreme caution and be prepared for sudden changes in visibility. Leave plenty of room between you and the motorist ahead of you, and allow extra time to reach your destination. Avoid sudden braking or acceleration, and be especially cautious on hills or when making turns. Make sure your car is winterized and in good working order.
Finally, the Flood Watch that has been issued for the Yosemite National Park Valley floor and all of Mariposa County outside of Yosemite, will remain in effect until this (Friday) afternoon.
Some heavy rain will continue at times. Flooding caused by excessive rainfall remains possible.
Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations.
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.
