MESA AND GARFIELD COUNTIES, Colo. — The Pine Gulch Fire in Colorado grew more than 37,000 acres Tuesday night into Wednesday, according to the Rocky Mountain Area Coordination Center. It's now 125,108 acres and the second-largest wildfire in Colorado history.
At more than 125,000 acres, the fire has surpassed the size of 2018's 108,045-acre Spring Fire.
The Rocky Mountain Incident Management Team said firefighting efforts at the Pine Gulch Fire are doing well on the northern and eastern side of the fire, but strong winds from a thunderstorm overnight caused the fire to expand westward.
The fire produced hours of lightning Tuesday evening, according to the National Weather Service out of Grand Junction. NWS explained that under the right circumstances, a pyrocumulus cloud can form and create lightning and thunder at the fire.
