Three separate wildfires erupted in the Black Hills region on Monday, have forced more than 400 homes to be evacuated, and have so far destroyed at least one house.

According to the authorities, thousands of acres of land have been burnt in the still-moving fires that haven't been contained.

At least 20 regions had been placed in the extreme grassland fire danger category, according to the National Weather Service, as of Monday.

No injuries have been reported so far. However, South Dakota Gov. Kristi Noem, who traveled to Rapid City to oversee the response, has said that “there have been losses and that is tragic.”

The Republican governor said the Schroeder Road fire started on private property, but the cause is still under investigation by officials.

The sheriff’s department warned earlier that it was a “very active and dangerous scene.” About 250 firefighters were battling the blaze on a windy afternoon when gusts ranged from around 50 mph to 72 mph, the Rapid City Journal reported.

“Law enforcement requests that citizens stay out of the area and use alternate routes,” a news release from the sheriff’s office posted on Facebook said.
