Major Winter Storm Set to Impact Sierra Nevada and Surrounding Areas

A significant winter storm is forecasted to affect the Sierra Nevada region, including California and Nevada, beginning late Sunday, February 15, 2026, and continuing through Wednesday, February 18. This storm is expected to bring heavy snowfall, strong winds, and hazardous travel conditions, marking it as the most powerful system since the Christmas period. Forecasters predict that the Sierra crest could receive between 4 to 8 feet of snow, particularly impacting areas such as Donner Pass and the Greater Lake Tahoe region.

The National Weather Service has issued winter storm watches effective from 10 p.m. on February 15 through 10 p.m. on February 18. Heavy snowfall is anticipated, with the Tahoe Basin expecting 18 to 30 inches at lake level and 2 to 5 feet in the Sierra. Wind gusts are projected to reach 45 to 55 mph in valleys, with even stronger gusts on the Sierra ridges, potentially leading to whiteout conditions. Travel disruptions are likely, with chain controls and possible road closures along Interstate 80.

In Reno, initial rain is expected before transitioning to snow, with a 25% to 60% chance of at least 2 inches accumulating by Monday night. Foothill communities are likely to see higher snow totals, contributing to slick road conditions.

This storm comes after a prolonged period of low snowfall in the Sierra Nevada, which has raised concerns about water supply for the summer months. Snow is crucial for replenishing runoff in streams, rivers, and reservoirs. The upcoming storm is expected to significantly boost seasonal snowfall totals, which have lagged behind average levels.

Some meteorologists have expressed concerns about the potential for flooding and mudslides due to the heavy rainfall accompanying the snow. The risk of travel disruptions and hazardous conditions has prompted warnings for residents and visitors to reconsider travel plans during the storm's peak.
