West Drought Summary

The southerly flow ahead of the eastern Pacific trough created an atmospheric river event that resulted in half an inch to 2 inches of precipitation across coastal areas from northern California to Washington. While the precipitation was helpful, it did not make up for deficits that have built up over the last several months; parts of Washington are still 10 inches or more below normal over the last 6 months. Severe drought was eliminated over southwest coastal Oregon where rainfall totals exceeded 3 inches and the total for the month was above normal. Much of Montana and parts of the northern Rockies received widespread 1 to 3 inches of precipitation; this resulted in contraction of D0-D2 in Montana. The rest of the West region received little to no precipitation. Abnormal dryness and severe drought expanded in Arizona, and extreme to exceptional drought expanded in southern New Mexico. USDA statistics indicated that three-fourths or more of the topsoil moisture was short or very short in Washington (82%), New Mexico (78%), Montana (77%), and Oregon (74%).
