The Frog Fire burning in the Maury Mountains southeast of Prineville is now 40% contained, according to fire officials.
Incident Commander Doug Johnson said the fire is burning 3,956 acres and remained within its current footprint overnight with minimal fire behavior, including in the areas that saw interior torching Sunday.
Monday firefighters will reinforce control lines around the perimeter of the fire and engage in mop-up operations, he said.
On the southern and eastern portions of the fire, crews will increase the depth of area cooled along the current perimeter to strengthen containment lines.
On the northwestern flank of the fire, resources plan to focus their mop-up efforts on concentrated sources of heat near the existing fireline.
A red flag warning for thunderstorms and gusty winds has been issued beginning at 12:00 p.m Monday through 11:00 p.m. Tuesday.
More than 480 firefighters are working the blaze with the help of three helicopters, six dozers and additional overhead support.
Overnight temperatures and good relative humidity recoveries along with increased cloud cover will moderate fire activity this morning providing advantageous conditions to secure lines and hot spots ahead of the afternoon’s potential weather event.
Northwest Incident Management Team 8 would like to thank the Brothers-Hampton and Post-Paulina Rangeland Fire Protection Association (RFPA) for their contributions to the suppression efforts of the Frog Fire.
Cooperators and partners such as the RFPA resources have been released to be available to respond to any new starts.
