(Mullen Fire Information, Facebook)

CASPER, Wyo. — The Mullen Fire had burned an estimated 161,964 acres in southeast Wyoming and northeast Colordo, according to the Mullen Fire Information Facebook page.

“After a day of fire behavior described as aggressive, the #Mullenfire_WY has grown to 161,964 Acres,” Mullen Fire Information said on Monday night. “The fire grew to the north in the area of South French Creek, and in the area south of Rambler near the Rob Roy Reservoir.”

“The fire was also very active in the area between Albany and Keystone, spotting out ahead of the main fire. Firefighters were successful in catching these spots. Late in the day crews were working in the southeast part of the fire in Division T to catch up with several spotfires that had started on the east side of Colorado Highway 127 as a result of strong winds from the northwest.”

An update posted to InciWeb at noon Tuesday noted that winds drove growth of the fire on Monday.

“Warm, dry, and windy conditions produced critical fire weather that yielded fire perimeter growth mainly on the northwest and then on the east central perimeter of the fire once the winds shifted out of the northwest,” the update says. “Crews worked to hold and improve lines widened by previous firing operations that were initiated to increase line depth and contain potential long-range spotting across WY230.”

“Point protection continued in the communities threatened by the Mullen Fire. Structure protection crews implemented strategies to defend structures in the event the flame front approaches.”

Critical fire weather is expected to continue Tuesday with westerly winds with gusts up to 30 mph forecast.

“Humidity is expected to lower to around 10% in the afternoon,” the update adds. “Smoke may impact air operations.”

“Warm and dry conditions are expected for Wednesday through Friday. Poor humidity recovery will be expected each night with somewhat diminished winds on Wednesday. Winds will increase again on Thursday and Friday.”

The fire remained 14% contained as of the latest estimate.

 The Southern Area Type 1 Blue Team took over command of the fire on Monday, taking over for the the Rocky Mountain Type 2 Blue Team.
