Heat

Extreme heat can be ‘invisible’ compared to wildfires and drought — but it’s more dangerous by far.

Scientists have a new name for a weather pattern reshaping how the West gets its water: so-called “snow-eater” heat waves.

A record-breaking stretch of high temperatures late last month was Colorado’s worst heat wave in the 75 years that such records have been collected, state climatologists said Tuesday.

Heat safety campaigns throughout the region focus on at-risk populations, outdoor workers and the unhoused.

The unseasonal warmth that broke longstanding temperature records across the West last week was a hit to Colorado's already low snowpack. Climate change drove the heat wave, but scientists say it's still an outlier in today's world.

Dillon and Steamboat Springs both recorded their warmest-ever March days. Both were recorded last week.

Before most residents have acclimated to the heat or set up home cooling systems, temperatures are rising to unseasonably high levels. New Mexico, Arizona, Colorado, and Utah are among 14 western states, expecting record-breaking heat this weekend.

Hot days and polluted air may be doing more than making people uncomfortable — they could also affect mental health. A new study from the University of Utah finds that short bursts of extreme heat, combined with certain types of air pollution, are linked to an increased risk of suicide.

A new report finds multi-day streaks of extreme heat are becoming stronger and lasting longer across the U.S., especially in Mountain West states. Experts warn that heatwaves are not only a health concern, but can strain energy resources.

A new report highlights the risks of extreme heat specific to rural areas.
