Rangeland Fire Danger Statement

National Weather Service Sioux Falls SD

337 AM CDT Thu Apr 4 2024



.DISCUSSION...



Winds weaken on Thursday with a prevailing north wind in most 

locations. Some variability in wind direction may be possible 

later this afternoon west of the James River. 



Temperatures continue to warm on Friday, and winds will increase 

slightly. A directional change to the southeast is expected Friday

morning, with afternoon gusts of 20 to 30 mph.



Greater concerns develop for Saturday as strong winds will 

develop quickly during the morning and intensify further in the 

afternoon. Southeast winds sustained up to 30 mph at times, may 

gust to 50 mph or higher in the afternoon and evening. While 

relative humidity values may only fall into the upper 30s, we 

still may see widespread elevated fire weather conditions through

the day. A close eye will be had on the afternoon relative 

humidity, which if it could fall towards 30 percent, may lead to 

critical fire weather conditions.

...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 FRIDAY AFTERNOON...The Grassland Fire Danger Index

will reach the high 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.

...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.
