Sioux Falls, SD – Very high grassland fire danger is expected across parts of southeast South Dakota Sunday due to warm, windy conditions.
According to the National Weather Service in Sioux Falls, temperatures well above seasonal averages combined with west winds gusting between 25 and 35 mph are increasing wildfire risk across the region.
Forecasters say dormant grasses in snow-free areas are especially vulnerable to ignition and rapid fire spread during the afternoon hours.
The Grassland Fire Danger Index shows very high fire danger across several areas, including parts of southeast South Dakota near Sioux Falls, Yankton, and surrounding communities. Other parts of the region are experiencing high fire danger conditions.
Meteorologists warn that low humidity levels, dry vegetation, and gusty winds can allow even small sparks to quickly start and spread fires.
Officials are urging residents to avoid outdoor burning and debris pile burning, which could easily ignite nearby dry grasses under these conditions.
Residents are also encouraged to report any signs of fire immediately, as early response can help prevent rapid spread.
The National Weather Service advises caution with equipment or outdoor activities that could create sparks, including machinery use, towing chains, or improperly extinguished cigarettes.
For farmers, rural residents, and outdoor workers across the region, windy conditions Sunday afternoon could significantly increase the risk of fast-moving grass fires.
Conditions are expected to remain elevated through the afternoon before winds gradually ease later in the day.
