Parts of the northern Rockies, Cascades, Siskiyous, Sierra and Wasatch still have an impressive snowpack.

More snow this week will only add to what's been a record snow season for some.

...

Despite recent warmth, there is still plenty of snow left to melt in the mountain West.

The Natural Resources Conservation Service's SNOTEL network estimated water content in the snowpack on Friday was an incredible 641 percent of average in parts California's Sierra and over 150 percent of the average for the date in parts of Wyoming, Idaho, Utah, northern New Mexico, western Nevada, Oregon and southern Washington.

In fact, a half-dozen locations from the Sierra to Wyoming have a record-high snow-water content for this time of year in 30 to 40 years of records, according to the SNOTEL network.

Northern California's Lassen Volcanic National Park recorded their second largest snowpack on record, beaten only by the 1982-83 season.
