FIRE DANGER STATEMENT
NATIONAL WEATHER SERVICE TULSA OK
253 AM CDT FRI APR 2 2021

...VERY HIGH GRASSLAND FIRE SPREAD RATES TODAY ACROSS NORTHEAST
OKLAHOMA...

FIRE WEATHER CONDITIONS WILL WORSEN LATER TODAY ACROSS NORTHEAST
OKLAHOMA, MAINLY TO THE WEST OF HIGHWAY 69. SOUTHERLY WINDS 
GUSTING 20 TO 30 MPH ALONG WITH TEMPERATURES IN THE UPPER 60S ARE
EXPECTED THIS AFTERNOON. LOW LEVEL MOISTURE RECOVERY WILL BE SLOW
TO NONEXISTENT TODAY, YIELDING VERY LOW HUMIDITY VALUES IN THE 20
TO 25 PERCENT RANGE. THESE CONDITIONS WILL ALLOW ANY FIRE STARTS 
TO SPREAD QUICKLY, ESPECIALLY ACROSS GRASSLAND AREAS.

FIRE FIGHTING PERSONNEL SHOULD EXPECT GRASSLAND FIRE SPREAD RATES
GENERALLY BETWEEN 200 AND 270 FEET/MIN ACROSS NORTHEAST OKLAHOMA.

AVOID OUTDOOR ACTIVITIES THAT COULD INADVERTENTLY START A FIRE, 
INCLUDING DISPOSING OF CIGARETTES PROPERLY. REPORT ANY WILDFIRES 
TO LOCAL OFFICIALS.

CONDITIONS SHOULD GRADUALLY IMPROVE OVERNIGHT TONIGHT AS HUMIDITY
VALUES INCREASE AND WINDS DECREASE.
