Red Flag Program

The purpose of the Fire Weather Watch and Red Flag Warning is to alert the public and land management agencies of developing weather conditions that,when combined with critically dry wildland fuels, could lead to dangerous wildfires...which will be issued using GFE Formatter and will be distributed under AWIPS Pil JANRFWJAN.

Criteria for Red Flag Events in the Forecast Area

Fire Weather Watches/Red Flag Warnings are issued when the combination of dry fuels and weather conditions are such that extreme fire behavior or ignition is occurring or is expected to occur. Forecasters will coordinate with local fire and land managers (State Forestry Commissions/US Forest Service) through the Interagency Coordination Centers of Louisiana...Arkansas and Mississippi to discuss the issuance of a Fire Weather Watch or Redflag Warning. In addition, issuing offices should coordinate with adjacent weather offices.

Below are some of the criteria to consider when evaluating Red Flag/Fire Weather Watch Conditions (conditions approaching this criteria) as of May 2008 for Mississippi:

1. Relative Humidity less or equal to  25%
2. 20 foot wind speed of greater or equal to 15 mph

For Louisiana Redflag/Fire Weather Watch Conditions:

1. Keetch-Byram Drought Indices of greater than 700
2. Relative Humidity less than 25%
3. Wind speed of greater than or equal to 14 mph

For Arkansas Redflag/Fire Weather Watch Conditions...updated May 2004.

1. Relative Humidity < 25%
2. 20 foot wind speed of greater or equal to 14 mph
3. Fuels critically dry, 10 hour fuels less than 10 percent

We consult both the state and federal agencies for the region before issuing this product.

FIRE DANGER STATEMENTS

The office will also issue Fire Danger Statements. This product is issued under rare circumstances of extremely dry or drought conditions for the entire or part of the region (AWIPS header JANSPSJAN). Distribution will be over NOAA Weather Radio, Internet and the Weather Wire.

The statement will have the following items:
1. Highlight one of these statements
   • ...FIRE DANGER INCREASING IN (Area to be Named)
   • ...HIGH FIRE DANGER CONTINUES IN (Area to be Named) we will not use the term Extreme.

2. Elaborate on the situation with a direct quote of the appropriate Fire Control Agency (State or Federal).

3. Indicate any changes (or no changes) in the weather situation expected over the next few days relative to the fire danger situation. We will not use fire or fire danger in describing the chances of rain, wind, or other weather parameters. We will leave fire behavior to the fire agencies.

4. Request for individual cooperation. The state or federal request that caution jbe exercise to help prevent forest and grass fires.

5. The statement will also mention burning bans that could be in force for a series of counties over portions of the state or a special statewide burning ban that is imposed by the governor.

6. Fire Danger Statements shall be issued only at the request of the forestry services...especially the state forestry agencies...since they cover the public lands of the state.

7. The Fire Danger product if so requested by the state and federal agency should be issued only from noon to 330 pm on NOAA Weather Radio. At most they may request broadcasts up to twice a week.

HIGH FIRE DANGER CONDITIONS CONTINUE ACROSS THE REGION

ACCORDING TO THE MISSISSIPPI FORESTRY COMMISSION, THE DROUGHT CONDITIONS HAVE MADE BURNING EXTREMELY HAZARDOUS. CONDITIONS ARE SUCH THAT A SPARK FROM EQUIPMENT, THE HEAT FROM A CATALYTIC CONVERTER, OR ANY HEAT SOURCE WILL START A FIRE. WINDY CONDITIONS COMPLICATE THE BURNING PROCESS BY FURTHER MAKING IT IMPOSSIBLE TO CONTAIN BURING DEBRIS OR TRASH, AND BY SENDING ANY WILDFIRES QUICKLY OUT OF CONTROL. LIGHTNING STRIKES FROM THUNDERSTORMS CAN QUICKLY START FIRES.

FIRES PLACE THE MISSISSIPPI FORESTRY COMMISSION, FIRE DEPARTMENTS, AND OTHER FIRE CONTROL SERVICES IN LIFE THREATENING SITUATIONS, AND CAN ENDANGER ENTIRE COMMUNITIES. PLEASE USE CAUTION AND HELP PREVENT FOREST AND GRASS FIRES. SINCE JULY 1ST OVER 50,100 HAVE BEEN CONSUMED IN OVER 3500 WILD FIRES ACROSS MISSISSIPPI.

THE MISSISSIPPI FORESTRY COMMISSION DOES NOT FEEL THAT ANY REASON FOR BURNING CAN BE JUSTIFIED AT THIS TIME. UNDER SUCH EXTREME CONDITIONS, WE URGE THE PUBLIC TO COMPLY WITH THE GOVERNOR'S BAN AND REFRAIN FROM ANY OUTDOOR BURNING. WHEN BARBECUING TAKE THE UTMOST CARE. DO NOT DUMP ASHES UNLESS YOU ARE CERTAIN THEY ARE COMPLETELY OUT. LIVE COALS CAN BURN FAR AS LONG AS ONE OR TWO DAYS AFTER BEING USED. OCCASIONALLYY, THERE WILL BE SOME RELIEF TO THE HIGH FIRE DANGER IN THE FORM OF SCATTERED SHOWERS AND THUNDERSTORMS. HOWEVER WUCH RELIEF WILL ONLY BE TEMPORARY WITH HIGH FIRE DANGER CONDITIONS RETURNING QUICKLY AFTER A FEW DAYS OF DRYING.
