Snowpack levels across many areas of the west are below average, especially in the southern Rockies and southern Great Basin states. The snow season was off to a slow start by late fall in many areas but has begun to pick up, especially in the northern and northwestern areas of the intermountain west.
The graphic below shows snowpack conditions as of January 4th, 2021.
The best snowpack conditions are in the Pacific Northwest drainages, especially in Washington, Oregon, northern Idaho and Montana (green and blue areas). However, the yellow, orange and red areas show where snowpack levels are below average. Note the large orange and red areas in Arizona, Utah and New Mexico.
In La Nina years, such as this one, the most favored areas to receive mountain snow is the in the Pacific Northwest and the Northern Rockies. La Nina years also favor below normal snowpack in the Great Basin and Southern Rockies. The current snow trends will likely persist through January. Expect the best mountain snows to be favored in the Northern Rockies and the Pacific Northwest.
