FIRE DEPARTMENT STATISTICS from www.firereporting.ok.gov recorded on 01/06/2019 thru 01/07/2019 

  • 1 Fire Burned 2 Acres (Cause: 1-Escaped Debris)
  • Initial attack fire activity noted through informal reporting and media outlets.

Statewide Discussion: 

Fire danger is expected to increase during the afternoon hours both today and tomorrow. Most of Oklahoma is now 10 days separated from wetting rains with above average temperatures working to facilitate strong drying conditions. Warm, dry and windy conditions will dominate during the afternoon hours ahead of a weather system that may bring precipitation back into parts of Oklahoma. Given the potential for increased initial attack activity Oklahoma Forestry Services will have engine and dozer resources prepositioned in Guthrie as well as a National Guard helicopter on active duty for the next two days.

Today: Despite cold temperatures this morning, low dewpoint temperatures prevented strong overnight moisture recovery in central and western Oklahoma. With afternoon high temperatures rising above normal, afternoon relative humidity values will likely fall below 30% statewide prompting increased receptiveness of dry, dormant vegetation and an uptick in initial attack activity. The highest fire danger today will develop south of I-40 and west of I-44 where very-high indices are expected. Increased fire danger will be present statewide. 

  • Southwest: Fine-dead fuel moisture values will be 4-5% with temperatures 57-64 and relative humidity values 16-21% under clear skies this afternoon. Light southwest winds this morning will increase to 12-15 mph gusting in excess of 20 mph at times. Rangeland fuels in the area are expected to deliver potential for moderate to rapid rates of fire spread 154-220 ft./min. and head fire flame lengths 11-14 ft.
  • Western/Oklahoma Panhandle: Temperatures will warm into the upper-50’s with afternoon relative humidity values 15-24% (reserving the lowest observations to western Cimarron County) yielding fine-dead fuel moisture values of 5% broadly and some sites observing 4%. Southwest winds 5-11 mph with some gusts around 15 mph will drive moderate rates of fire spread 90-145 ft./min. with head fire flame lengths 9-11 ft. Firefighters in the western half of the Oklahoma Panhandle should be mindful of potential for a gradual wind shift this afternoon from southerly to northerly although wind speeds are expected to be rather light.
  • Central/Eastern Oklahoma: Areas along and east of the I-35 corridor will see relative humidity values fall into the 23-29% range this afternoon as temperatures warm into the 57-61 range facilitating receptive fine-dead fuels at 6% moisture. Some sites may dip to 5% briefly this afternoon. Southwest winds 5-13 mph with some occasional higher gusts over grass dominated fuels will support rates of fire spread 85-137 ft./min. with head fire flame lengths 9-11 ft. Grass/brush fuels will exhibit 40-65 ft./min. with average flame lengths around 9 ft. while timber fuels will offer ample opportunity for suppression.

Wednesday: Dry conditions continue across Oklahoma and southerly winds will increase elevating concern for the potential of fast-moving, wind-driven wildfires. There is potential for high sky cover to overspread the area during the afternoon which may serve to limit fire danger indices to some extent stalling relative humidity values from bottoming out. Nonetheless, dry and dormant vegetation will support rapid rates of fire spread. Initial attack activity will likely increase across the state, although the lack of complete alignment in the fire environment will fortunately limit the potential for extended duration incidents.
