Intermountain West Drought Early Warning System

Conditions for the week of July 4 – 10

Portions of Arizona, New Mexico, southern Utah, and eastern Nevada did see some monsoon activity with scattered precipitation in both states.  The hot and dry conditions have allowed for quite a rapid expansion of drought in portions of Utah and Colorado.  A full category degradation was introduced over much of eastern Utah and western Colorado, bringing most of the area into exceptional drought conditions.  Moderate drought was expanded to most of northwest Colorado while moderate drought and abnormally dry conditions migrated to the east in Colorado to include the Denver area.
