Mountain snowpack was low in the Southwest, high in the Northern Rockies

So far this year, snow levels across the Southwest — in particular the Sierra Nevada mountains and Southern Rockies — have been below average and much lower than those seen in 2017. The Northern Rockies, however, experienced a cold and wet February and winter, which led to record-high mountain snowpack in some areas.
