Blizzard conditions can be expected throughout the northern portion of California beginning Thursday, February 29, and running through the weekend, according to a National Weather Service alert.

The forecast calls for five to 10 feet of snow for elevations above 5000 feet and one to four feet for elevations up to 3000 feet.

Lighter accumulations can be expected below elevations of 2000 feet.

Wind gusts could reach 65 miles per hour.

The alert, released by the weather service’s Sacramento office, warned of downed trees, near zero visibility, whiteout conditions, travel delays, power outages and road closures.

Meteorologists across the country took to X (formerly known as Twitter) to share the warnings and commented that it may be the strongest blizzard to hit to California.
