Thirteen of Colorado’s 64 counties have a least some area in exceptional drought, with most or all of their remaining area in severe conditions.
The coming week’s forecast offers no hope for relief. The National Weather Service has issued an excessive heat warning for portions of west central Colorado for Monday through Friday. Such alerts are unusual for the state. Temperatures in the area – which includes Grand Junction in Mesa County – could reach 110 degrees, creating risks for heat-related illnesses, which can be deadly.

Improvements in the eastern Colorado began in mid-March as significant snow provided relief. During May, thunderstorms continued to bring rain to the state’s eastern plains, resulting in drought-free conditions for most northeast counties by the end of the month.
The first drought-free area in Colorado since mid-2020 appeared in late April.
Overall, 55 percent of the state is drought-free, up from 51 percent last week, with an additional four percent in abnormally dry conditions, down from six percent in the previous week. Moderate drought covers six percent of Colorado, down from eight percent, while severe drought remains unchanged at six percent. Extreme drought dropped from 13 to 12 percent. Exceptional conditions expanded from 16 to 18 percent. Total does not equal 100 due to rounding.
