Sioux Falls, SD – Elevated fire danger is returning to the Sioux Falls area Monday and intensifying into Tuesday, with strong winds and dry conditions raising concerns for fast-spreading grass fires across Minnehaha County and eastern South Dakota.
According to the National Weather Service in Sioux Falls, relative humidity levels will drop as low as 20–30% Monday, combined with southwest winds between 12 and 22 mph. These conditions place much of the region in a “high” fire danger category, especially in open rural areas and along roadways.
By Tuesday, conditions are expected to worsen. A cold front will bring north winds of 30 to 45 mph, pushing fire danger into the “very high” category across Sioux Falls and surrounding counties. Humidity levels will remain low, between 23–38%, further increasing the risk of rapid fire spread.
Drivers along highways such as I-29 and I-90 near Sioux Falls should be alert. Strong winds can quickly carry flames across dry grass near roadways, reducing visibility and creating sudden hazards.
Officials advise residents to avoid outdoor burning, properly dispose of cigarettes, and secure trailer chains that could spark fires on roadways.
The elevated risk follows a brief calmer period Sunday, but officials stress that conditions early this week could change quickly, especially Tuesday afternoon when winds peak.
