Expected
Effective:
June 17, 2026 - 10:26am
Expires:
June 17, 2026 - 7:00pm
Description:
...RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM MDT THIS EVENING DUE
TO GUSTY WINDS AND LOW RELATIVE HUMIDITY FOR SOUTHERN BLACK HILLS,
FALL RIVER COUNTY AREA, CUSTER COUNTY PLAINS, PINE RIDGE AREA,
BADLANDS AREA, BENNETT COUNTY AREA, SOUTHERN CAMPBELL, AND WESTON
COUNTY PLAINS...
.A cold front moved through early this morning. Behind the cold
front, strong northwest winds from 25 to 35 mph with gusts up to 55
mph have been reported. Minimum relative humidity values will dip as
low as 18 percent, which is higher than normal thresholds. However,
the strong winds will make up the difference as well as antecedent D2
to D3 drought and very dry weather over the past 1-2 weeks. Thus,
critical fire weather conditions are expected for parts of
northeastern Wyoming and southwestern South Dakota late this morning
through the early evening hours.
* AFFECTED AREA...Fire Weather Zones 315, 317, 321, 322, 325, 326,
332, and 333.
* TIMING...Until 8 PM MDT this evening.
* WINDS...Northwest winds 25 to 35 mph with gusts from 40 to 55 mph.
* RELATIVE HUMIDITY...Relative Humidity as low as 18 percent.
* IMPACTS...Any fires that develop will spread rapidly. Outdoor
burning is not recommended.
Instruction:
A Red Flag Warning means that critical fire weather conditions are
either occurring now, or will shortly. A combination of strong winds,
low relative humidity, and warm temperatures can contribute to
extreme fire behavior.
