As of July 13, 2021, 89% of the West is in drought and 25% is in Exceptional (D4) Drought. Both are U.S. Drought Monitor records. Much of the West was drought free just over 14 months ago, but drought conditions began developing around May 2020. A poor summer 2020 monsoon season followed by snow drought in winter 2020-21 worsened conditions in California and the Southwest. Record-shattering temperatures and dry conditions in the Northwest in early summer 2021 caused conditions to rapidly deteriorate in a region that was already facing multi-year precipitation deficits.

The National Weather Service Central Region developed 2021 Summer Hazard Outlooks in coordination with the NOAA National Centers for Environmental Information, National Integrated Drought Information System (NIDIS), and National Water Center; U.S. Department of Agriculture; National Weather Service River Forecast Centers; and National Interagency Fire Centers' Geographic Area Coordination Centers. This outlook highlights the various Summer hazards that could occur and potential impacts across the Western U.S.
