Rangeland Fire Danger Statement
National Weather Service Sioux Falls SD
411 AM CDT Sat Apr 18 2026

.DISCUSSION...

Similar to yesterday, elevated fire concerns are expected across
the area mainly due to continued dry and breezy conditions. As
mixing resumes with the diurnal cycle, dew points will gradually
decrease into the afternoon resulting in relative humidity values
in the 17-22 percent range. This combined with increasing west-
northwest winds with gusts between 30-40 mph will result in high
fire danger across most areas. However, with lush fuels; decided
to forgo any fire-related headlines this go around since the fuels
will hinder fire spread.

Looking ahead, the drier conditions will persist for most of the
upcoming week. However, breezier conditions will be a bit more hit
or miss. As a result, elevated fire concerns look to be possible
every other day through midweek. With this in mind, make sure to
limit any activities that could create a spark.

...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 moderate 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.
