Rangeland Fire Danger Statement

National Weather Service Sioux Falls SD

426 AM CDT Sat Oct 10 2026



.DISCUSSION...

South winds could increase quickly by mid-late morning, with peak

gusts 30-40 mph for most locations between 10 am and 3 to 4 pm.

Locally higher gusts near 45 mph will be possible along/near the

Buffalo Ridge in southwest Minnesota at times. Wind speeds may be

on a downward trend as we reach the lowest humidity levels of

25-35% mid-late afternoon. This is more likely toward south-

central South Dakota where gusts ease to less than 30 mph as

humidity falls to near 20 percent.



While these strong winds and low afternoon humidity levels will

push the Grassland Fire Danger Index (GFDI) into the High category

for most locations today, this reflects fire danger for native

grasses, which still maintain some relative greenness. However,

with harvest season underway and crops significantly dry in many

areas, field activities may be a driving force behind a greater

wildfire potential. The GFDI for these fully cured fuels suggests

considerable concern through the Tri-State area, so extreme

caution should be used when working outside today.

...HIGH FIRE DANGER...



The Grassland Fire Danger Index will reach the high category

this afternoon. Unfavorable weather conditions and low

moisture content of grasses, and other dry organic material

on the ground, indicate that there is a high potential for

a fire to spread.. Outdoor burning should be restricted to

early morning or evening hours, when wind speeds are usually

lower and the relative humidity is higher.



OUTLOOK FOR SUNDAY 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.

...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 moderate category.
