Sierra Nevada Storm

Advisories have been issued by the National Weather Service for the border area between California and Nevada in anticipation of an early winter storm. This system is expected to deposit over a foot (30 centimeters) of snow on the higher parts of the Sierra, coupled with wind gusts that could reach 100 mph (160 kph) over the mountain ridges.

Effective from 4 p.m. Saturday to 4 a.m. Sunday, these winter weather advisories cover regions ranging from the vicinity of Lake Tahoe near Reno to areas south of Yosemite National Park, including Mammoth Lakes in California.

Anticipated Winter Disturbance:

In preparation for an approaching winter storm, the National Weather Service has alerted those along the California-Nevada border. The storm is likely to deliver in excess of a foot of snow to Sierra’s peaks and bring winds that may gust as high as 100 mph.
These advisories will be active from Saturday afternoon at 4 p.m. until the early hours of Sunday at 4 a.m.
The NWS indicates that snowfall could intensify to rates of 1 to 2 inches per hour in certain locales.

Snow accumulations of 3 to 8 inches (7 to 20 centimeters) are anticipated above 6,500 feet (1,980 meters), potentially reaching up to 14 inches (35 centimeters) above 8,000 feet (2,440 meters).

The Reno weather service warns of possible treacherous driving conditions and reduced visibility, with snowfall intensities reaching 1 to 2 inches per hour (2.5 to 5 centimeters) in the heaviest squalls.

Furthermore, strong winds might lead to damage to trees, drifting snow, and perilous conditions for boating on Lake Tahoe, with wave heights predicted to be between 2 to 4 feet (60 to 122 centimeters).
