National Drought Status

Northeastern Colorado and much of Texas received heavy precipitation this week, improving drought in both regions. In contrast, drought conditions have intensified across California and the Northwest, and California is seeing an uptick in spring wildfires compared to last year. As of May 4, 2021, 38.9% of the U.S.—and 84.1% of the West—is in drought.
