DISCUSSION
ISSUED AT 252 PM CDT SAT OCT 4 2025
HOT, DRY AND WINDY CONDITIONS WILL LEAD TO WIDESPREAD HIGH TO
VERY HIGH GRASSLAND FIRE DANGER TODAY. AFTERNOON MINIMUM
HUMIDITY OF 27-40%, WITH DRIEST CONDITIONS IN SOUTH CENTRAL
SOUTH DAKOTA. HOWEVER, SOUTH WINDS GUSTING AS HIGH AS 35 TO 40
MPH WILL OVERCOME THE MARGINAL HUMIDITY LEVELS, ESPECIALLY WHERE
GRASSES ARE MORE CURED OR CROPS ARE READY FOR HARVEST. WITH
THIS IN MIND, PLEASE USE CAUTION WITH MACHINERY THAT GETS VERY
HOT OR CREATES SPARKS.
BREEZY CONDITIONS CONTINUE OVERNIGHT AND INTO SUNDAY. AREAS WEST
OF I-29 CAN EXPECT GUSTS OF 30-35 MPH OVERNIGHT AND INTO SUNDAY
LATE MORNING. AREAS TO THE EAST COULD SEE GUSTS OF 35-40 MPH IN
TO THE EARLY AFTERNOON. HUMIDITY LEVELS WILL FALL TO 30-40%, AND KEEP
THE GRASSLAND FIRE DANGER IN THE HIGH CATEGORY IN MANY AREAS,
SO CONTINUED CAUTION IS ADVISED.
THROUGH THE DAY SUNDAY A COLD FRONT MOVES THROUGH THE REGION.
TEMPERATURES WILL BEGIN TO COOL SUNDAY, AND BE IN THE 60S FOR
MONDAY. DRY CONDITIONS WITH COOLER TEMPERATURES AND LIGHTER
WINDS ARE EXPECTED FOR NEXT WEEK, ALLOWING FOR LESS DANGEROUS
HARVESTING CONDITIONS.
PEOPLE ARE URGED TO EXERCISE EXTREME CARE WITH RESPECT TO OUTDOOR
ACTIVITIES THAT COULD CAUSE GRASS FIRES. AVOID EQUIPMENT THAT CAN
CAUSE SPARKS NEAR DRY GRASS OR BRUSH. DO NOT TOSS CIGARETTES ON
THE GROUND. REPORT NEW FIRES QUICKLY TO THE NEAREST FIRE
DEPARTMENT OR LAW ENFORCEMENT OFFICE.
