Climate change has increased the number of fire weather days in our region, according to a new Climate Central study.
Fire weather days occur when a combination of hot, dry, and windy conditions linger for at least two hours in a given day. Since 1973, those days have risen significantly in many counties across the Mountain West.
Kaitlin Trudeau, is an applied climate scientist with Climate Central, said the fire season in many places is lasting longer and when fires do ignite, they are often more intense.
"There's some places that now see two more months of fire weather conditions each year, compared to the 70's. And that's two more additional months," Trudeau said.
"It's important to acknowledge that the fires we're seeing now are very, very different fires," she added. "They're much larger now, they burn faster, hotter, they're more destructive, and they're much harder to get a handle on."
The increase in fire weather days is especially dramatic in Arizona, Nevada, and New Mexico. Much of Colorado and parts of Wyoming and Idaho also saw significant increases.
In Utah, increases ranged from about two weeks in the south-central part of the state to almost a month and a half in western Utah.
Such days not only heighten the risk for wildfires, they can also trigger power shut-offs and unhealthy air quality.
