Snow levels are forecasted to drop dramatically, from around 7,000 feet to as low as 4,500 feet. Chain control regulations will be enforced at elevations above 5,000 feet.
Officials recommend postponing non-essential travel until at least Tuesday. They warn that this storm may be unusual for May but its impacts are significant and potentially dangerous for anyone caught unprepared.
Key facts:
