West Drought Summary

The story over the region has been the slow start to the current water year with the lack of both rain (in the lower elevations) and snow (in the upper elevations). The anomaly has been the northern Rocky Mountains in that the wet pattern over the last several weeks has allowed for a full category improvement to the drought status over Montana with all areas of extreme drought being removed this week. In the central Rocky Mountains and Four Corners regions, drought conditions continued to intensify, with moderate and severe drought expanding over Colorado, New Mexico, Utah, and southern Wyoming. Abnormally dry conditions were introduced into Oregon, northern California, and western Idaho this week in response the dryness. Heavy rain at the end of the period brought the first significant rainfall to southern California and portions of the desert Southwest this winter, bringing with it mudslides and flooding as the rain saturated areas burned earlier.
