West Drought Summary

A storm system moving through the southwest United States led to moderate or heavy precipitation in parts of New Mexico, Arizona, Utah, and Colorado, with the heaviest Colorado precipitation taking place in the San Juan Mountains. Abnormally dry conditions in south-central New Mexico improved. However, the heavier precipitation missed the Four Corners region, worsening the long-term precipitation deficits. Most of California and Nevada also remained dry this week. Above-normal temperatures over the last few months, combined with precipitation deficits over most of the Southwest, led to the continuation of drought in much of the Southwest region. Moderate drought expanded through parts of the Sierra Nevada, where very low snowfall, short- and seasonal-range precipitation deficits, and warm temperatures so far this winter continued. Some ski areas have even closed because of the lack of snowfall. Abnormally dry conditions expanded through the rest of the Central Valley in California, where precipitation deficits over the water year and streamflow continued to degrade. Moderate drought expanded over south-central Oregon, where short-term and water year precipitation deficits intensified.
