SALT LAKE CITY — A storm moved through Utah overnight bringing heavy snow to the mountain areas and substantial snowfall to the valleys.
The National Weather Service issued a Winter Storm Warning for the Salt Lake Valley at midnight and it will remain in effect through 6 p.m. Tuesday. Although valley floors were originally expected to receive between 2-6 inches of snow and 6-12 inches along the benches, those numbers may decrease as the day progresses.

Mostly rainy, wet conditions are being found in the valleys while the mountains get hit with snow. The Winter Storm Warning may be extended if lake effect snow remains during the Tuesday afternoon hours.
A Winter Storm Warning has also been issued for the Wasatch Mountains south of Interstate 80 from 9 p.m. Monday through 6 a.m. Wednesday. Most mountain areas are expected to receive up to 12 inches of snow, but the Cottonwoods may get hit with over two feet.
Valleys are forecast to receive the following snow totals:
- Mountain Valleys: 3-8 inches
- Salt Lake Valleys: 1-3 inches
- Central Valleys: 1-2 inches

The snow has had a mostly minimal impact during the Tuesday morning commute in northern Utah, as drivers experience rainy conditions. However, if possible, people should delay their trips until the heavy band of snow dissipates on Tuesday morning.
Traction laws have been enacted for some mountain roads, including up both Cottonwood canyons, and drivers are urged to check for avalanche mitigation road closures.
Watch: Morning traffic moving slowly due to winter conditions
As of 9 a.m., Salt Lake City International Airport was experiencing only minor delays due to the weather, with most flights departing about 25 minutes late due to deicing procedures.
