The Cameron Peak Fire is currently 125,006 acres and 21% contained. Cooler conditions yesterday and freezing temperatures with good humidity recovery last night are aiding firefighter progress on the fire. 852 firefighters are now working on this fire.
At 7:00 this morning Northwest Incident Management Team 6 began managing the fire. The Incident Commander is Shawn Sheldon.

Timber (Grass and Understory)
Timber (Litter and Understory)
High elevation mixed conifer with moderate dead and down fuel loading, along with a high percentage of beetle killed lodge pole. Lower elevation grass fuels are drying and more available to burn. ERC values for this area are currently above the 90th percentile.
Fire behavior showed increased activity today in the form of active flame fronts with low to moderate rates of spread. Backing, flanking, and a couple of short uphill runs with torching and short-range spotting were observed from interior islands of unburnt fuels. Fire activity along existing control features remained moderate. Fire behavior is responding to a very dry air mass over the fire area which is producing very low daytime relative humidity and very poor overnight humidity recovery. Gusty afternoon winds are contributing significantly to drying of the fuels and increases in observed fire behavior. Forecast overnight humidity recovery is very poor again tonight and expect fire behavior to remain active after sunset.
Fire activity increased today as warmer and drier condition continued. Equipment and crews continue to build direct fire line where it is safe and makes sense to do so. Firefighters are currently engaged in holding the Manhattan Road and engaged in structure protection. Mandatory evacuations were issued for the communities of Red Feather Lakes, Crystal Lakes and Glacier View. Fire activity, topography, bug-killed fuels, critical fire weather including winds gusts over 60 mph have been observed. Lack of crews and critical resources has made direct line tactics difficult to obtain. Resources are monitoring limited fire activity within Rocky Mountain National Park. Other divisions are currently continuing to mop-up, monitor and patrol. Structure protection is in place and plans to implement continue to be developed and refined as the fire continues to move towards values at risk. Engines will continue to patrol and mop-up as needed. Structure assessments,structure protection implementation and control features continue in the Crystal Lake, Red Feather Lakes, Glacier View and neighboring communities. Structure triage assessments have been completed in the Falls River corridor, Rocky Mountain National Park, Estes Park, Estes Park Valley, Glen Haven and Storm Mountain areas and surrounding communities. Proposed lines are in place to begin indirect line construction in and around the communities of Glen Haven, The Retreat, Cedar Park, and Storm Mountain should fire activity dictate.
|Projected Incident Activity|
12 hours: Flare ups with torching and short-range spotting are possible interior and along control features. Fire behavior will likely remain active, at least in the interior, for a couple of hours after sunset until winds subside. Very poor humidity recovery again tonight.
24 hours: Fire activity is forecast to steadily increase with continued drying of fuels. A slight change in wind direction from the north may expose new areas of the fire to wind influences, particularly in Division Z and Division U on the south end of the fire where there are minimal barriers to spread.
Rapid warming occurred with widespread temperatures in the 60s and some 70s. Humidity rapidly fell in the 13-17% range underneath sunny skies. Northwest winds were gusting to 20-25 mph. Poor recovery is expected again tonight.
Wednesday temperatures will be a couple of degrees cooler, but still dry with humidity falling into the teens again.Northwest winds will be weaker and are expected out of a northerly direction in the afternoon. Thursday a weak backdoor cold front will result in an east-southeast wind on the eastern side of the fire with temperatures a few degrees cooler.
72 hours +:
Friday-Sunday high temperatures will most likely be in the 60s and northwest ridgetop winds are expected to increase Friday through Saturday with gust to
30 mph. Minimum RHs are expected to persist in 15-20% range.
