FIRE DEPARTMENT STATISTICS** from recorded on 02/09/17 thru 02/10/17

No New Activity Reported

Multiple new fires noted through media outlets.

Statewide Discussion: Red Flag Warning in effect from 11:00 AM through 7:00 PM for all of central and eastern Oklahoma, areas of western and southwestern Oklahoma. Warning also issued for Cimarron County in the Panhandle from 12:00 PM through 7:00 PM.

Eastern Oklahoma – Southerly winds through the day sustained 15-25 mph with gusts as high as 40 mph combined with temperatures 70°-75° and relative humidity values as low as 25% in northern counties to 40% further south will set the stage for rapid rates of fire spread in grass and timber fuels. 100 and 1,000 hr. fuels (larger diameter size classes) are critically dry and have contributed to increasing fireline intensity, longer duration fires and increased fireline intensity. Rate of spread in typical grass fuels in excess of 300 ft./min with head fire flamelenghts averaging 12-16 ft. should be anticipated while timber dominated fuels ROS 65-100 ft./min. and flamelengths averaging 8ft. are likely.

Central Oklahoma – Unimpressive overnight moisture recovery and increasing fire weather will deliver substantial fire behavior concerns by mid-morning. Temperatures in the mid to upper 70°’s and relative humidity values around 25% will result in very receptive fine fuels through the day. Low large fuel moisture will also increase the probability of problematic fire behavior in wooded areas. South to southwest winds 17-23 mph with gusts as high as 35 mph will support very rapid rates of fire spread. Native grasses and unmaintained pastures will potentially deliver rates of spread nearing 400 ft/min. at the head of the fire with flamelengths nearing 15 ft. (20-30) ft. in rank native grass. Timber fuels typical of the area will likely exhibit ROS around 60-80 ft./min and flamelengths 8-12 ft. Mixed timber/brush fuels may have a tendency to produce problematic fire behavior including group tree torching, and given the current fuel moisture regime short-range spotting should be anticipated.

Western Oklahoma – Relative humidity values 13-23% and temperatures around 80° will promote very receptive fuels with Probability of Ignition at 80%. Fine-dead fuel moisture will likely fall to or below 5% today. Southwest winds10-16 mph with gusts near 20 mph translate to rate of spread averaging 300-350 ft./min. and head fire flamelengths averaging 15 ft. or greater. In areas where wind, topography and continuous fuels are aligned expect much more intense fire behavior.

Special Note to Firefighters:

Saturday – Unseasonable (hot) temperatures 80°-90°, low relative humidity in central and western Oklahoma (as low as 10%), poor overnight moisture recovery, winds increasing into the afternoon and an approaching cold front entering northern Oklahoma late in the burning period will result in an upper-end fire danger day. Firefighters are encouraged to check fires from previous days this morning prior to initial attack on new fires ramps up insuring the older fires are secure and mopped up. Given the current fuel moisture regime including very dry large fuels, incident commanders and fire managers should expect longer duration initial attack and mop-up commitment.

OFS will have Task Force Resources located in central Oklahoma and National Guard has 4 helicopters on duty.
