West Drought Summary

30 to 60-day SPI along with soil moisture indicators support an expansion of abnormal dryness (D0) and moderate drought (D1) across southeastern Montana. 30 to 90-day SPIs, recent warmth, and soil moisture led to a 1-category degradation in northwestern Montana. Following major improvements during the past few months across California and the Great Basin, no changes were made this week after little or no precipitation. Drought of varying intensity is designated for parts of Oregon and northern Idaho where precipitation averaged below-normal for the Water Year to Date (October 1, 2022 to May 1, 2023).
