Strong winds on Sunday caused four wildfires in northwest Colorado and northeast Utah to grow substantially. They are all in mountainous areas between 7,000′ and 9,400′. The three fires in Colorado listed here were all described as exhibiting extreme fire behavior. It is early in the year to have multiple large fires in Colorado. They are all in remote areas with difficult access and have the potential to continue to expand.
According to information available Monday morning there were a total of 84 personnel assigned to the four fires, which included one hand crew. With nearly 8,000 already committed to numerous fires in Arizona, Utah, New Mexico and other states, it could cause a person to wonder about the availability of firefighting resources as we get deeper into the traditional fire season.
Oil Springs Fire
The largest of the four fires we’re looking at today is the 5,000-acre Oil Springs Fire in Colorado which has prompted evacuations. It has forced the closure of Highway 139 43 miles north of Grand Junction and 26 miles south of Rangely. Structures and oil and gas infrastructure are threatened. It is burning at elevations up to 7,400 feet. Winds gusting at 25 to 39 mph Sunday while the relative humidity was in the single digits resulted in the fire spreading several miles to the southeast and crossing Highway 139. A Red Flag Warning is in effect for the area just south of the fire. The wind is expected to decrease Monday but the RH will be in teens in the afternoon. Resources assigned to the fire Sunday evening included 3 engines, no hand crews, and no helicopters for a total of 20 personnel. A Type 2 Incident Management Team has been ordered. There are two other smaller fires 8 to 10 miles east of the Oil Springs Fire.
Sylvan Fire
The Sylvan Fire is burning above 9,000 feet 13 miles south of Eagle, Colorado just west of Sylvan Lake. The strong wind on Sunday pushed it about two miles to the southeast while exhibiting extreme fire behavior. Using early Monday morning heat sensing data from a satellite it appears to have grown to approximately 800 acres. As of Sunday evening there were no firefighting resources on the fire.
West Fire
The West Fire is 41 miles southeast of Rock Springs, Wyoming on the Wyoming-Colorado border three miles east of the Utah border. It is burning at elevations up to 9,400 feet. The early Monday morning heat sensing data indicates it has burned about 1,700 acres. Structures, oil and gas infrastructure, and sage grouse habitat are threatened. Resources assigned to the fire Sunday evening included 1 hand crew, 3 fire engines, and 1 helicopter for a total of 64 personnel.
Sego Fire
The lightning-caused Sego Fire is in a very remote area of Utah 52 miles east of Price in rugged, difficult to access terrain. Smoke from the fire is very visible on the satellite photo at the top of this article. Heat sensing data indicates it had burned approximately 500 acres by early Monday morning.
