Intermountain West Drought Early Warning System

Conditions for the week of November 7-13

In the Rockies, widespread snow showers were observed in the Front Range and adjacent foothills as well as in the Sangre de Cristo Range, leading to improvements on the map in north-central and south-central Colorado. Overall, Colorado’s snowpack is off to a positive start with above-normal snow water equivalent (SWE) levels in the Front Range, Sangre de Cristos, and the Mosquito Range of central Colorado. In New Mexico, recent snowfall and above-normal SWE levels led to reduction of Extreme Drought (D3) in the north-central part of the state. In eastern New Mexico, recent storm activity and improved soil moisture levels have improved conditions leading to reduction in areas of Moderate Drought (D1) and Severe Drought (D2). In central Arizona, wet conditions during the past 90-days led to reduction in areas of Moderate Drought (D1).
