A winter storm warning is in effect for parts of northern and central California, with the Sierra Nevada mountain range expected to receive up to 2 feet of additional snow accumulation on top of the snow that fell over the weekend. The National Weather Service has warned of hazardous travel conditions and the potential for wind gusts up to 45 mph.

Why it matters

Severe winter weather can disrupt transportation, damage property, and pose risks to public safety in affected regions. The Sierra Nevada mountains are a popular destination for outdoor recreation, so heavy snowfall can impact both residents and visitors.

The details

The National Weather Service has issued a winter storm warning for areas above 4,500 feet in the Sierra Nevada, including the cities of Chester, Blue Canyon, and Quincy. The warning calls for an additional 12 to 18 inches of snow, with up to 2 feet at the highest peaks. Snowfall is also expected down to 4,000 feet, with 2 to 4 inches of accumulation. Gusty winds up to 45 mph are also forecast, making travel highly discouraged.

  • The winter storm warning is in effect until 11 p.m. local time on April 12, 2026.
  • Parts of the Sierra Nevada saw nearly 8 inches of snow accumulation on April 11, 2026, with the UC Berkeley Central Sierra Snow Lab predicting an additional 18 to 36 inches over the night of April 11 and throughout April 12.
