Event narrative

At the beginning of the month of October, the US Drought Monitor analyzed an area of Extreme (D3) Drought as covering roughly 60% of Utah Zone 023 - Eastern Uinta Mountains, with the remaining 40% under Severe (D2) Drought conditions. With the 10/14 Drought Monitor update, Extreme (D3) Drought coverage was reduced to 40%, with 60% of the zone under Severe (D2) Drought. No substantial changes were noted between this point and the end of the month.

Wider weather episode

A dry end to September and a dry start to October kept drought conditions consistent across much of eastern Utah and western Colorado at the start of the month. However, the arrival of deep tropical moisture from the remnants of Tropical Storms Priscilla and Raymond helped to substantially improve drought conditions, especially across southwest Colorado. In this region, drought was completely eradicated. Only portions of northeast Utah and northwest Colorado, where the deep tropical moisture did not reach, saw drought conditions persist more or less unchanged.
