- Alaska’s Panhandle faces the most severe combination of cold and snow, including 16–20 inches near Hyder and wind chills near White Pass cold enough for frostbite in about 30 minutes.
- The Cheyenne office warned the Sierra Madre and Snowy Range in Wyoming could see 2–5 feet of accumulation, with life‑threatening exposure risks for anyone caught unprepared.
