Sierra Nevada Winter Weather Through Tuesday

The National Weather Service has issued a Winter Storm Warning for Yosemite National Park (above the Valley floor) and the western slope of the northern Sierra Nevada, from 4 PM this afternoon until 4 PM Tuesday.

Heavy snow is forecast for elevations above 6,500 feet.

The snow levels this afternoon will start out around 6,000 to 7,000 feet, before lowering to around 4,500 to 5,500 feet over the weekend. The snow levels will then rise to around 5,000 to 6,000 feet, early next week.

A brief break in snowfall is expected from late Saturday afternoon into Sunday morning with lighter snow showers.

The total snow accumulations above 6,500 feet, will range from ten inches to five feet. The higher you go, the more the snow.

Winds gusts could range from fifty to fifty-five mph. Strong winds can cause extensive damage to trees and power lines.

Persons are urged to stay indoors until conditions improve. If you must go outside, dress in layers. Several layers of clothes will keep you warmer than a single heavy coat. Cover exposed skin to reduce your risk of frostbite or hypothermia. Gloves, a scarf, and a hat will keep you from losing your body heat.

Persons should delay all travel if possible. Travel could be very difficult to impossible. Roads, and especially bridges and overpasses, will likely become slick and hazardous.

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. Keep an extra flashlight, food, and water in your vehicle, in case of an emergency.
