Why heavy winter rain and snow won't be enough to pull the West out of a megadrought

Skiers cruise down the slopes at Snowmass ski area in Colorado. This winter has already delivered snow totals above 130% of average, but climate scientists say it will take more than one wet winter to pull the arid West out of a 23-year drought.

This winter could provide some relief for parched reservoirs in the Colorado River Basin, but climate scientists warn that the severe drought won't end with one wet season.
