West Drought Summary

Half an inch to locally 2+ inches of rain fell over parts of Arizona, New Mexico, and Utah, but most of the West received no rain this week. High evapotranspiration due to persistently hot temperatures, low streamflow and soil moisture, and lack of precipitation over 1-month to 12-month time scales resulted in the expansion of D2 and D3 in northwest Washington, expansion of D2 in eastern Washington and the Idaho panhandle, and expansion of D1 and D2 and the introduction of D3 in western Oregon. Rain from weather systems in past weeks, especially the remnants of Hurricane Hilary, resulted in contraction of D1 in central Oregon, D0 and D1 in Utah, and D0 to D3 in western Montana. While parts of New Mexico received rain this week, other parts were dry. The weather system that dumped rain on Texas also soaked east-central New Mexico, so drought contracted there. But prolonged dryness resulted in expansion of D1 and D2 in central to northeast New Mexico and D3 in northwest and southern parts of the state, as well as D3 expansion in adjacent southeast Arizona. According to USDA reports, more than two-thirds of the topsoil was short or very short of moisture in New Mexico (87%), Washington (83%), Montana (82%), and Oregon (74%), and more than two-thirds of the subsoil moisture was short or very short in New Mexico (87%), Montana (79%), Washington (78%), and Oregon (75%). Half or more of the pasture and rangeland was in poor or very poor condition in Washington (65%) and Arizona (57%).
