Northern California’s Rain Totals: A Seasonal Overview

As we move further into 2026, Northern California is experiencing a notably wet spell, especially following a dry and warm March. This new weather pattern is of particular significance as it influences the state’s water resources amid fluctuating snowpack levels.

Current Weather Conditions

At Donner Summit, snow is falling steadily, requiring chain controls due to slushy road conditions at elevations over 7,200 feet. This area, known for its winter sports, has seen a resurgence in snow, as indicated by recent reports that highlight the impact of weather changes on travel advisories.

Caltrans has urged drivers to exercise caution, particularly on the downslope into Truckee, where conditions can become slick. The last significant snowfall on this mountain was recorded last year, and while the current conditions may feel similar, last year’s situation included more consistent snowfall earlier in the season.

Snowpack and Rain Totals

The upcoming final snow survey for the year takes on heightened importance as officials assess the Sierra Nevada’s snowpack, which was at just 66% of average after December and February storms. A recent survey on April 1 revealed that statewide, the snowpack was a disappointing 18% of average, with even lower figures recorded in specific regions such as the Northern Sierra at 6% and the Central Sierra at 20%.

The critical snowpack levels this time of year are vital for California’s water supply, influencing agriculture and drought preparedness. Therefore, the recent arrival of rain and snow is beneficial after several dry months.
