Mammoth Lakes, California – Mountain travel could become dangerous within hours Tuesday morning as heavy snow and strong winds begin impacting Mono County’s higher elevations.
According to the National Weather Service in Reno, a Winter Weather Advisory takes effect at 5 a.m. Tuesday and continues through 5 a.m. Wednesday for areas above 8,000 feet. Snowfall totals of 6 to 12 inches are expected, with localized amounts up to 14 inches along the Sierra crest. Winds along exposed ridges could gust as high as 60 mph, creating blowing snow and sudden whiteout conditions.
Travel through Mammoth Lakes, Lee Vining, and Bridgeport will likely deteriorate quickly Tuesday morning, especially on high-elevation routes and mountain passes. While lower elevations along and west of US-395 may only see 1 to 2 inches, strong crosswinds and reduced visibility could still make driving hazardous.
Gusty winds may bring down tree branches, adding to travel concerns and the potential for isolated road closures. Drivers should delay non-essential travel, carry tire chains, and check Caltrans conditions by calling 511 before heading out.
The advisory remains in place through early Wednesday, and additional updates may follow if snowfall totals or wind impacts increase overnight.
