Sioux Falls, South Dakota – Elevated fire danger is expanding across eastern South Dakota today and Wednesday as warm, dry, and windy conditions persist.
According to the National Weather Service in Sioux Falls, gusty winds, unseasonably warm temperatures, and low relative humidity combined with dormant grasses will create conditions favorable for rapid fire spread.
Temperatures are forecast to run 20 to 30 degrees above normal, with record or near-record highs possible in some areas. Wind gusts across the region are expected to reach 30 to 40 mph at times Tuesday and Wednesday.
Forecasters warn that outdoor fires could quickly spread in dry grasses. Residents are urged to avoid activities that may spark a fire, including roadside burning or equipment use that produces sparks. Burning is discouraged during this period.
Drivers along Interstate 29 from Sioux Falls to Brookings and Interstate 90 west toward Mitchell may experience strong crosswinds, especially in open rural stretches. Blowing debris is possible in exposed areas.
Relative humidity values are expected to drop significantly during the afternoon hours, further increasing fire risk before conditions gradually improve later in the week.
Farmers, ranchers, and motorists traveling through grassy areas should remain cautious, particularly when parking vehicles on dry vegetation.
Officials continue to monitor conditions statewide as elevated fire danger remains in place through Wednesday.
