The Fire Weather Forecast
through the weekend and into early next week is very dynamic.
Much of northern and western
Oklahoma will see above normal temperatures, low relative
humidity and strong gusty winds
that will create fast moving and erratic fire behavior.
There is a frontal boundary expected
during this period that will also abruptly change
wind direction and bring the
potential for very gusty winds.
A Fire Weather Watch is presently in place for 13 northern and western
counties in Oklahoma.
Please refer to http://www.weather.gov/
for the latest updates to the fire weather forecast.
Significant fire danger indices
will exist in much of northern and western Oklahoma over the next five days. Any fire that becomes established will likely
exhibit extreme rates of fire spread and erratic fire behavior. This is especially true for both Saturday and
Tuesday with the present forecast.
Grass / Pasture: Maximum of 250-300
ft./min., head fire flame length 3-6 ft.
Grass / Prairie: 300-450 ft./min. ( 5.1 mph), head fire flame length
100-200 ft./min, head fire flame length 10-18 ft.
Litter(Forest): 20-60 ft./min., head fire flame length 3-8 ft.
Fire Weather and resulting Fire Behavior predictions for tomorrow indicate
the frontal assault should be avoided – do not fight the fire at the head. Anchor the fire at advantageous point (road,
creek, cold black) and flank the fire if utilizing direct firefighting tactics. Work the fire from the black if possible to
provide for quick escape to a safety zone.
Avoid placing yourselves in a situation where unburned fuel is between
you and the fire.
All firefighters are advised to take particular note of the 10 Standard
Fire Orders with specific interest in the first three: (a complete list of the
Standard Firefighting Orders below)
Keep informed on fire weather conditions
Know what your fire is doing at all times.
Base all actions on current and expected
behavior of the fire.
Oklahoma Forestry Services will have Task Forces
prepositioned to respond with engines, dozers and overhead personnel.
OFS will coordinate with OHP to have wildfire
operational specialists in the air to assist with fire size-up and operational
Fixed-wing tanker aircraft are available.
National Guard helicopters are available
OFS will have an Air Attack Supervision platform
County Wildland Task Force Resources should be
prepared for mobilization.
To request assistance, call the
Resource Hotline (800) 800-2481

common denominators of fire behavior on tragedy fires:
- On relatively
small fires or deceptively quiet areas of large fires.
- In relatively
light fuels, such as grass, herbs, and light brush.
- When there is an
unexpected shift in wind direction or wind speed.
- When fire
responds to topographic conditions and runs uphill. Alignment of
topography and wind during the burning period should always be considered
a trigger point to re-evaluate strategy and tactics.
