Winter’s Last Stand? Spring Storm Threatens Sierra Snow and Valley Rain

Just when Californians thought spring had arrived, Mother Nature has other plans. A powerful late-season storm is barreling toward the Sierra Nevada, threatening heavy snow, gusty winds, and valley rain—disrupting travel and outdoor plans this weekend.

What to Expect from the Unseasonable Storm

• Sierra Snowfall: Up to 18 inches of fresh powder above 6,000 feet, with localized higher totals near peaks.
• Valley Rain: Widespread showers, with up to 1.5 inches possible in lower elevations.
• Wind Gusts: Strong winds up to 50 mph could cause power outages and hazardous driving conditions.
• Travel Warnings: Chain controls likely on major mountain passes like Donner Summit and I-80.

Why This Storm Is Unusual

Late March storms aren’t unheard of, but this system’s intensity stands out. A lingering polar jet stream dip is colliding with Pacific moisture, creating an explosive mix. Ski resorts may celebrate the powder, but commuters and hikers should brace for delays.

1. Timing: Peak impacts arrive Friday night through Sunday morning.
2. Cold Temperatures: Valley lows dipping into the 30s—20s in higher elevations.
3. Flood Risk: Rapid snowmelt could trigger minor creek flooding next week.

How to Prepare

Caltrans advises checking road conditions before mountain travel. Homeowners should clear drains to prevent pooling, and gardeners may want to delay planting tender annuals.

What Do You Think?

• Is climate change making spring storms more erratic, or is this normal variability?
• Should ski resorts extend seasons due to late snow, despite environmental concerns?
• Are weather warnings becoming overly alarmist, or do they save lives?
