EAGLE COUNTY, Colo. — The Derby Fire more than doubled in size again overnight, according to InciWeb data Thursday morning, as evacuation orders continued for parts of Eagle County.
The Derby Fire is now 2,624 acres in size and remains 0% contained. In an update later Thursday, fire officials said at least one structure had been lost in the Sugarloaf Mountain area due the fire.
Mandatory evacuations that were ordered for residents of Sweetwater Road, Red Dirt Creek, and sections of Colorado River Road on Tuesday were still in effect, but Zone 266-A along Colorado River Road had been moved to pre-evacuation status.
Derby Mesa Loop also remains under a pre-evacuation notice at this time, according to Eagle Valley Wildland officials. Evacuees were advised to head to the Eagle County Public Safety Information website for an up-to-date evacuation/pre-evacuation map.
The Eagle County blaze, burning about 15 miles north of Dotsero in the White River National Forest, was sparked by lightning on Saturday.
There have been no reports of structural loss or injuries.

The lightning-sparked Lee Fire, first reported on Aug. 2, is burning 18 miles southwest of Meeker in Rio Blanco County.
Three homes and 12 outbuildings have burned so far in the Lee Fire, according to officials in Rio Blanco County, who said firefighters made steady progress on the north side of the fire and continued to work along Hogback Ridge Thursday.
Over the weekend, the Rio Blanco County Sheriff’s Office downgraded several evacuation zones from GO (red) to SET (yellow) and from SET to READY (green). The Garfield County Sheriff’s Office downgraded Zone 70 on the east side of Highway 13 in northern Garfield County from GO (red) to SET (yellow). Other zones have not changed.
Crews on Wednesday completed nearly four miles of chipping, which is the act of processing large debris into smaller woodchips which are dispersed over a wide area. That work will continue Thursday, with firefighters also patrolling and targeting remaining hot spots.
The Rio Blanco County Sheriff's Office said a partial closure of the White River National Forest was also in effect due to the fire within the Blanco Ranger District west of and including the Long-Lost Trail system.

The Crosho Fire continues to burn in the Routt National Forest but has seen no growth since the weekend, according to the latest update from fire officials.
Sixty-seven structures continue to be threatened by the fire, according to the Wyoming Type 3 Incident Management Team, but none have burned as of Thursday morning.
Pre-evacuations remains for residents along County Road 90 to the north, County Road 92 to the west, parts of Highway 131 to the east and just north of Milk Creek to the south.
Closures remain in effect for the following roads:
- Intersection of Routt County Road 15 and Routt County Road 17
- Intersection of Routt County Road 25 and Routt County Road 132A
- Rio Blanco County Road 8 (Dunckley Pass) closed at intersection of Rio Blanco County Roads 8 and 19
Fire officials said Wednesday containment is increasing thanks to the hard work of firefighters cold trailing, mopping up, and strengthening lines around the fire’s perimeter. Progress remains steady despite hot and dry weather, rugged terrain and overhead hazards.
An emergency closure order is in place for the Medicine Bow-Routt National Forests around the fire. The Routt County Emergency Incident Map is updated with road closures.

Size: 9,872 acres
Containment: 27%
First reported: July 28
Cause: ⚡️
Location: 5 miles west of Rico in the San Juan National Forest
Evacuations 🏠: No current evacuations
Fire officials said in an update that increased cloud cover helped moderate fire behavior later in the day Wednesday. On Thursday, crews will continue to see hot and dry conditions, however, moisture will begin to slowly flow in from the southwest.
"Due to an inversion in the Stoner Canyon area, the canyon will see a thermal belt developing, allowing active burning conditions late into the night," fire officials said.
Fuels are still extremely dry with crews encountering new spot fires daily, officials added, saying Stoner Canyon continues to be the area with the most fire activity.
