Late-Season Winter Storm Warning Issued For Sierra Nevada

Late-Season Winter Storm Warning Issued For Sierra Nevada...

A significant winter storm warning has been issued for California's Sierra Nevada mountains through Sunday, with forecasters predicting heavy snow and dangerous travel conditions. The National Weather Service warns of 1-3 feet of snow above 6,000 feet elevation, with localized amounts up to 4 feet possible at higher peaks.

The unusual late-season storm comes as April typically marks the transition to spring conditions in the region. Meteorologists attribute the system to a strong low-pressure trough moving south from Alaska, colliding with moist Pacific air. Chain requirements are already in effect on major mountain highways including I-80 and Highway 50.

Ski resorts like Palisades Tahoe and Mammoth Mountain, which planned to close this weekend, may extend operations due to the fresh powder. However, authorities warn backcountry travelers about heightened avalanche risks from the heavy, wet snow expected Friday night through Saturday morning.

Pacific Gas & Electric reports preparing for potential power outages across the Sierra foothills. The storm could impact 30,000 customers in Placer, El Dorado and Nevada counties according to outage prediction models. Crews are prepositioning equipment along vulnerable transmission lines.

This weather system follows an already record-breaking snow year for the Sierra, where snowpack currently measures 104% of average. The California Department of Water Resources notes the additional precipitation will help maintain water reserves, but could delay summer runoff projections.

Travelers are advised to check Caltrans road conditions before mountain trips this weekend. The storm's timing coincides with spring break for many California schools, potentially disrupting family travel plans across the Sierra passes.
