Statewide Discussion:  

A Red Flag Warning is in effect for Cimarron, Texas, Beaver, Harper, Woods, Ellis, Woodward and Roger Mills counties.  Panhandle counties are expected to experience critical fire weather from 11:00 AM through 8:00 PM and northwest counties   from Noon through 7:00 PM.  Across the warned area temperatures 95° to 100°+ and relative humidity values 7-15% will result in critically low fuel moisture and very receptive fuels.  Sustained winds around 20 mph with frequent gusts in excess of 30 mph will produce wind-driven fire and erratic fire behavior on any going fire. Poor moisture recovery in the overnight hours results in fuel availability early in the burning period.  Lagging rainfall totals and above normal temperatures have resulted in low live fuel moisture, and the associated heat-sink will have minimal effect on fire behavior.  Fire behavior in typical grass fuels has the potential to exhibit rates of spread on the head fire near 250 ft./min (in excess of 300 ft./min on any slope aligned with wind) and average flame lengths 10-15 ft.  Grass and shrub mixed fuels may likely exhibit rates of spread in the 165 to 200 ft./min. with flame length in excess of 15 ft.  Any glowing fire brand landing in receptive fuels will have an 80% probability of ignition.

Fire danger will be high to very-high today across most of western Oklahoma.  Western counties, outside of the warned area, and west of a line from Alfalfa County to Cotton County will see temperatures 90°-95° and relative humidity values bottom out this afternoon in the 21-30% range.  This afternoon, southwest winds at 10-20 mph gusting to  25-29 mph will promote opportunity for any going fire to exhibit rapid rates of fire spread.  Fire weather conditions will be near critical across much of the area today, and potential fire danger should not be underestimated.  

Well above normal temperatures will preside over all of Oklahoma today along with strong and gusty south-southwest winds. Relative humidity values east of the I-35 corridor are expected to remain well above critical levels creating moderate fine fuel moisture levels.  However, seasonality and fading live fuel moisture have resulted in increasing fine-fuel availability.  Erratic fire behavior should be expected on any going fire; however fuel moisture, shading in timbered areas and overnight moisture recovery should provide good probability of success during initial attack.

Special Note to Firefighters:
Dry and dormant fuels combined with unseasonably warm temperatures, stiff winds and low relative humidity can produce rapid rates of fire spread in typical Oklahoma fuels.  Utilize safe and effective engine tactics by establishing an anchor point and progressing up the fire flanks while working from the black.  Take a few moments to reference the Oklahoma Wildland Tailgate issue that focuses on Engine Tactics.  This issue can be found at www.forestry.ok.gov/tailgate .
