Update: First Winter Storm Will Impact The Sierra Nevada

The first winter storm of the season will bring periods of snow to the higher elevations of the Sierra Nevada, beginning this Friday and continuing through the weekend.

The National Weather Service has issued a Winter Storm Watch for the Northern and Central Sierra Nevada above the 5,000 foot elevation, from Friday morning through Sunday evening.

The snow levels will begin above the pass levels, before falling down to 4,000 to 5,000 feet early Friday night.

There may be some lighter precipitation by Saturday afternoon, before possible heavier additional snow moves through Saturday night through Sunday.

The total snow accumulation above 5,000 feet, will range from six to nineteen inches.

The winds could gust as high as sixty mph on exposed ridgetops. Gusty winds could bring down tree branches.

Mountain travel delays, significant reductions in visibility, chain controls, and slippery road conditions are all possible, especially during the overnight hours. Campers and hikers should prepare for wintry conditions.

Meanwhile, the Mariposa Pollution Control District has issued an Air Quality Alert for Mariposa County that will expire today. This is due to smoke impacts from the Creek Fire and SQF Complex Fire.

Exposure to particle pollution can cause serious health problems, aggravate lung disease, cause asthma attacks and acute bronchitis and increase the risk of respiratory infections.

Residents are advised to use caution as conditions warrant. People with heart or lung diseases should follow their doctor`s advice for dealing with episodes of unhealthy air quality.

Additionally, older adults and children should avoid prolonged exposure, strenuous activities or heavy exertion, as conditions dictate.

For additional information, call the local Air District office.

A Winter Storm Watch means there is potential for significant snow, sleet or ice accumulations that may impact travel. Continue to monitor myMotherLode.com for the latest forecasts.
