West Drought Summary

The coastal regions of the Pacific Northwest as well as the northern Rocky Mountains again had the most precipitation. Areas of southern Nevada and the desert regions of southern California and western Arizona finally recorded some precipitation. Areas of southern California that had experienced fires late last year were impacted by mudslides from the heavy rains that inundated the region. Even with the precipitation in Oregon, the water year continues to be well below normal for precipitation, which allowed for the expansion of abnormally dry conditions in Oregon, western Idaho, and southern Washington. A new area of moderate drought was introduced from central Oregon to western Idaho. In Utah, the low snow and snow water equivalency values caused an expansion of severe drought in central Utah and moderate drought in northeastern Utah. Abnormally dry conditions were pushed to include all of northern Utah and extreme southwestern Wyoming. In eastern New Mexico, severe drought conditions were expanded over the region.
