The Schroeder Fire, burning in Pennington County, just a mile west of Rapid City limits, started Monday morning, said Rob Powell, the incident commander, during a news conference.
The blaze has so far charred about 1,900 acres and remains zero percent contained, according to a web page set up for fire updates.
Evacuations are in place through multiple subdivisions in the area, Powell said, adding some roads were closed as well.
The fire started on “private property,” according to South Dakota Gov. Kristi Noem, but officials say an investigation is ongoing into the cause and origins of the blaze.
The dangerous weather conditions have made it a harder battle for the more than 200 firefighters on the scene.
No injuries or deaths have been reported.

The two fires in the area have been dubbed the 244 Fire and the Keystone Fire.

The Keystone Fire was downsized Monday evening from 30 acres to 15 acres, according to the site.
“Fire officials request that people from the public to please stay away from the area and allow firefighters to do their work,” it said.
No businesses are being threatened by the flames at this time, the governor said during the news conference.
“I do want to remind everybody that this is an incredibly fluid situation,” she said. “That these winds are a major factor and that as they shift and change and we get those gusts, that’s when the can jump and we’re going to have to stay pretty mobile.”
