Statewide Discussion: 

Red Flag Warning in effect today, October 120, 2019 for Cimarron, Texas & Beaver Counties from 1:00 PM through 9:00 PM.

Critical fire weather is expected to develop in the Panhandle counties today over very dry fine fuels. Fire danger indices will also be high to very-high across the western third of the state. The smattering of rain Friday evening into Saturday morning will have little to no effect as the early freeze over one week ago thrust much of the herbaceous fuel load into transitional dormancy and rainfall amounts fell well below wetting qualification. Storms are in the forecast overnight Sunday with highest probability in the eastern third of Oklahoma while far western counties remain dry. Elevated fire danger will remain across western Oklahoma and in the Oklahoma Panhandle in the post-frontal fire environment with decent precipitation chances absent in the forecast.

 Oklahoma Panhandle: 69⁰-76⁰ under partly cloudy skies with relative humidity values 8-11% during the peak of the burning period. Herbaceous fuels have rapidly transitioned toward dormancy with increasing fine-fuel availability. Fine-dead fuel moisture values will be 3% at most locations with not ruling out the possibility of 2% observations given clear skies. Southwest winds early will shift to westerly as the cold front approaches then increasing northwest sustained 17-24 mph gusting at times in excess of 30 mph. Rates of fire spread on established, free-burning fires in non-grazed/non-hayed grass dominated fuels will be near 300 ft./min. (3.4 mph) with head fire flame lengths 12-17 ft. Firefighters should expect problematic and periods of extreme fire behavior where fuels are in alignment with wind and topography. Additionally, firefighters should remain vigilant to the timing of the approaching cold front and associated wind shift effecting direction of fire spread.

Northwestern and Western-tier Counties: Elevated fire weather is expected during the afternoon and evening hours. 75⁰ (northwest) - 86⁰ (southwest) and relative humidity values 16-23% combined with an extended separation from wetting rains and frost/freeze effects will deliver readily available fine fuels with 3-5% 1-hour fuel moisture observations expected. Southwest winds shifting west then northwest late in the burn period 8-15 mph gusting 20-30 mph with the passage of a cold front. In grass dominated fuels typical of the area, head fire rates spread ranging 185-265 ft./min. (2.1-3.0 mph) with flame lengths averaging 10-13 ft.

 Warm and breezy conditions will be present across the state today although relative humidity values are not expected to approach critical values in central and eastern Oklahoma. While increased initial attack activity is likely, fire suppression efforts are expected to be successful. Rain and storm chances increase to the east, although western Oklahoma is expected to remain dry in large part. Fire danger is expected to remain elevated in the Oklahoma Panhandle and western counties on Monday, although winds should be much lighter facilitating successful initial attack efforts.

Firefighter Safety Message: Dry fuels, warm temperatures, stiff winds and low relative humidity can produce rapid rates of fire spread in typical Oklahoma fuels. Fire behavior predictions indicate that frontal assault should not be attempted. Instead, 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 .
