A newly defined type of heatwave is reshaping spring across the western U.S., with major consequences for snowpack, floods, and water supplies.

"Snow-eater" heatwaves decimate the snowpack that western states depend on.

Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin.

Unseasonably warm weather that rapidly melts snowpack is becoming more widespread in the U.S. West and happening earlier in the year.

Snow-eater heat waves are defined, identified, and shown to nearly double usual western United States spring snowmelt rates.

An early spring California heat wave is feasting on what’s left of the Sierra Nevada snowpack, raising wildfire and drought concerns.

Satellite images and data show California’s snowpack collapsing at an unprecedented rate during a March heat wave.
