West Drought Summary

Very warm and generally dry weather occurred over the last week in California, Oregon, and Washington. Meanwhile, in southern Nevada, southeastern California, and parts of Utah and Arizona and New Mexico, scattered monsoonal rains continued, leading to localized heavy rains. Because of the short- and long-term precipitation deficits present in much of the region coming into this past week, large amounts of rainfall were needed for drought conditions to improve. Improvements in extreme and exceptional drought conditions occurred over parts of Arizona where enough rain fell to substantially reduce the ongoing deficits. Conditions in Washington continued to dry out in the short term. Combined with warm temperatures, this led to the development of moderate drought in the Olympic Peninsula and the expansion of abnormal dryness in parts of eastern Washington. Abnormally dry conditions also developed in parts of the Idaho Panhandle because of precipitation deficits and low streamflow.
