Rangeland Fire Danger Statement

National Weather Service Sioux Falls SD

345 AM CDT Mon May 5 2025



.DISCUSSION...

Overall greening of new growth fine fuels appears sufficient to 

keep grassland fire danger on the low side. However, areas west 

of I-29, and especially west of US Highway 81 will see south to 

southeast winds gusting to around 25 mph at times. Humidity 

levels also remain low, bottoming out at 20 to 30 percent this 

afternoon. This combination of breezy winds and low humidity may

result in elevated fire danger in localized areas where the tall 

dormant grasses are still the dominant fuel. 



These localized fire danger concerns will ease over the next few 

days, in response to lighter winds Tuesday, and slight increases

in humidity levels by Wednesday and Thursday.

...LOW FIRE DANGER...



The Grassland Fire Danger Index will reach the low category 

this afternoon. Favorable weather conditions or a high moisture 

content of grasses, and other dry organic material on the 

ground, indicate that the probability of a fast moving fire is 

low. Outdoor burning under these conditions can usually be 

with reasonable safety precautions, but should be monitored.



OUTLOOK FOR TUESDAY AFTERNOON...The Grassland Fire Danger Index

will reach the low category. 



The grassland fire danger product reflects fire danger for native

grasses. It is not intended for cured agricultural crops, nor

will it reflect conditions in road ditches which have been mowed.
