Winter storm slams western U.S., brings heavy snow, drenching rain
The powerful storm system is expected to move east over the next several days, forecasters said.
www.cbsnews.comI don’t currently have live tool access to pull up-to-the-minute updates, but I can share the latest widely reported context on Sierra Nevada winter storm warnings and what they typically involve.
Direct answer
- As of the most recent widespread briefings, a winter storm warning for the Sierra Nevada typically signals heavy snowfall, strong winds, and dangerous travel conditions, with potential road closures and chain-controls above certain elevations. Expect significant snowfall totals at higher elevations and hazardous travel on major routes nearby.
Key points you’ll usually see in these warnings
- Snow accumulation: higher elevations often 1–2 feet or more, with the possibility of much heavier snowfall on peaks.
- Wind: gusty winds can cause whiteout conditions and drifting snow.
- Travel impacts: interstate and mountain passes may require chains, with potential closures or lengthy delays.
- Timing: warnings are usually issued 24–48 hours before peak impacts and can be extended if forecasts shift.
What you can do now
- Check the National Weather Service or local weather service for the Sierra Nevada region (California/Nevada) for the latest warning status, timings, and snowfall forecasts.
- If you’re planning travel or outdoor activities, consider postponing trips, carry supplies, and prepare for possible road closures and chain requirements.
- Monitor highway advisories (Caltrans and state transportation departments) for current chain controls and closure information.
