Intermountain West Drought Early Warning System

Conditions for the week of April 19-25

Precipitation amounts were highly variable, but well-placed moderate to heavy rain and wet snow (1-3 inches liquid equivalent, locally more) led to reduction in Abnormal Dryness (D0) and Moderate Drought (D1) over southern-most portions of Wyoming and northern Colorado. Additional D1 and D0 reductions were made in eastern Colorado despite lighter rainfall (half inch or less), as precipitation totals over the past 90 days were now mostly well above normal, with 30-day totals locally more than three times normal. There were no changes made to the drought depiction from the Rockies into the Southwest.
