Compared to one year ago, the area in drought in the western U.S. shrank from 89% to 73%, while the area in Exceptional Drought (D4) dropped from 25% to 7%. Spring storms in the Pacific Northwest and Northern Rockies removed drought in parts of those regions. A robust summer monsoon has improved drought in parts of the Southwest, especially western New Mexico. The Southwest, California, and even parts of the Northwest have been stuck in a 20+ year megadrought, influenced by climate change.
