A slowly growing, nearly contained wildfire burning on Colorado’s Western Slope is now the fourth-largest on state record, according to fire officials.
As of Monday night, the 90% contained Lee fire had scorched 138,844 acres between Meeker and Rifle. It grew by 1,086 acres on Monday, after multiple days with minimal to no growth.
The new acres consumed by the Lee fire bumped the wildfire from fifth-largest to fourth-largest in Colorado history, passing the 137,760-acre Hayman fire that sparked in 2002, according to the Colorado Division of Fire Prevention and Control.
The Lee fire is now less than 200 acres away from becoming the third-largest wildfire on state record. Currently, that ranking belongs to the 2020 Pine Gulch fire that burned 139,007 acres.
Rain showers and thunderstorms are forecast across the Western Slope again on Tuesday, bringing much-needed moisture to the state, fire officials said. Previous hot, dry and windy conditions fueled rapid fire growth in multiple counties across western Colorado, charring thousands of acres outside of the Lee fire.

Lee and Elk fires, near Meeker
The largest wildfire burning in Colorado — now the fourth-largest ever recorded in the state — consumed more than 1,000 new acres after a week of slow growth and increased containment, fire officials said.
As of Monday night, the 138,844-acre Lee fire burning between Meeker and Rifle was 90% contained, fire officials said.
All mandatory evacuation orders were lifted Saturday, and areas on pre-evacuation status were downgraded to monitoring status on Monday.
No new evacuation orders were issued overnight Monday, despite the new fire growth. An updated evacuation map for Rio Blanco and Garfield counties is available online.
The Lee fire and nearby Elk fire, which consumed more than 14,500 acres before reaching full containment last week, have together destroyed at least five homes and 14 outbuildings, fire officials said.
Extreme drought, high temperatures and strong winds fueled rapid growth on both fires, which were sparked by lightning west and east of Meeker on Aug. 2.
Thunderstorms are most likely near Meeker and Rifle between 9 a.m. and midnight on Tuesday, according to the National Weather Service. Rain showers, which are also expected in that period, could continue through 3 a.m. Wednesday before a brief reprieve.
Rainy weather is expected to continue on Wednesday and Thursday, forecasters said.
While the rain is helpful, afternoon thunderstorms also increase the risk of gusty winds, frequent lightning and flash flooding along burn scars, fire officials said.
Road closures tied to the smaller Crosho fire near Yampa were lifted Monday afternoon. That fire has burned 2,073 acres and is 81% contained.
Derby fire, in Eagle County
A wildfire burning on the edge of Eagle and Garfield counties has scorched more than 5,300 acres, fire officials.
The Derby fire is burning on 5,346 acres with no containment, up roughly 100 acres from Sunday and 1,200 acres from Saturday, fire officials said Monday. No size update was available Tuesday morning.
“We have totally changed the pattern from hot and dry,” said meteorologist Ryan Fliehman in a Monday evening briefing. “I’m afraid we might get too much rain. We are still having chances of precipitation six days out.”
Rain has forced some fire crews to pull back, and crews need to take extra care to avoid damaging dirt roads, which have turned muddy, Operations Chief Ben Patton said.
No containment has been reported on the fire, but officials hope to start solidifying the first bits of containment in the coming days.

The Derby fire was discovered on “remote, rugged terrain” in the White River National Forest, about 15 miles from Dotsero in Eagle County, on Aug. 17, according to the U.S. Forest Service.
It differs from the others burning in Colorado in that it started at higher elevations and has tried to push downhill at night.
Mandatory evacuations and pre-evacuations are in place for the northwest corner of Eagle County, including the town of Gypsum, and an eastern section of Garfield County.
Evacuations were lifted for Sweetwater Valley and Sheep Creek at 10 a.m. Monday, allowing limited access for residents to return home, according to fire officials. Those who need to access Sweetwater Valley and Colorado River Road are being asked to limit their driving to between 10 a.m. and 4 p.m. to avoid disrupting emergency operations.
Updated Eagle and Garfield County evacuation maps are available online.
At least one building has been destroyed by the wildfire, but it’s unclear what type of building it was.
Parts of White River National Forest remain closed in Eagle and Garfield counties, including southwest of Sweetwater Lake to the west rim of Deep Creek Canyon, according to the U.S. Forest Service. Some BLM lands are also closed, including north and west of Gypsum, north of Coffee Pot Road, west of the Colorado River, east of the White River National Forest boundary and south of Derby Creek.
