Grand Junction, CO – Residents in Grand Junction should prepare for a dangerously hot and smoky Tuesday, with temperatures expected to peak near 97°F and haze from wildfire smoke reducing air quality by early afternoon. Outdoor activities may become hazardous, especially for children, older adults, and those with respiratory issues.
According to the National Weather Service, smoke from nearby wildfires will drift into the Grand Valley overnight Monday into Tuesday, lingering through midday before skies gradually clear. East to southeast winds in the morning will shift northwest, potentially stirring dust and worsening conditions for sensitive groups.
Travelers on Interstate 70 and local roads could face reduced visibility in pockets of smoke, particularly in low-lying areas. Health officials urge limiting strenuous outdoor activity, staying hydrated, and using indoor air filtration if possible.
The heat will persist into Wednesday, with highs near 99°F before a slight chance of showers and storms returns Thursday. This stretch of high heat and dry air raises fire danger, and more advisories may follow if winds increase.
