Rangeland Fire Danger Statement

National Weather Service Sioux Falls SD

401 AM CDT Sat May 10 2025



.DISCUSSION...

Today will be the less warm and less windy day of the weekend, 

though some areas west of I-29 could still see winds gusting 

20-30 mph during the afternoon. This combined with relative

humidity falling to 15-25 percent will result in elevated fire

danger, mainly in areas where dry/dormant grasses are prevalent.



Sunday remains the day of greater concern this weekend, as south

winds increase and temperatures warm back into the upper 80s to

lower 90s. Afternoon wind gusts as high as 40 to 45 mph are 

expected west of U.S. Highway 81 toward central South Dakota,

ranging down to lower gusts of 30 to 35 mph along and east of

Iowa/Minnesota State Highway 60. Very dry air remains in place

with afternoon humidity falling as low as 13-20 percent over

much of the area. While conditions may vary depending on local

greenness levels in the fine fuels, the strong winds and very

dry air will result in near critical to critical fire weather

conditions Sunday afternoon. A Fire Weather Watch remains in

place, and has been expanded to include Gregory County South

Dakota. 



Little change is expected Monday through Wednesday, though 

wind speeds and humidity levels may ease slightly each day. 

However, with no rainfall expected, fine fuels may continue to 

dry further, so elevated to potentially critical fire weather 

conditions look to persist through the first half of next week.



Do not leave open fires unattended. Please be sure that your

campfire is completely out.

...MODERATE FIRE DANGER...



The Grassland Fire Danger Index will reach the moderate 

category this afternoon. Marginal weather conditions or 

lowering moisture content of grasses, and other dry organic 

material on the ground, indicate that there is some potential 

for a fire to spread. Any outdoor burning should be closely 

monitored.



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

will reach the very high category.

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

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

...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.
