Red Flag Warnings have been issued across much of South Dakota as strong winds increase the risk of wildfires should any fire be started Wednesday. Officials are also on high alert as firefighters continue to battle the Palmer Gulch wildfire.

Firefighters were able to successfully hold containment lines on the Palmer Gulch Fire, according to the latest update on the Great Plains Fire Information blog site published Tuesday. Located three miles southeast of Hill City, South Dakota, the fire has burned 87 acres and is 40% contained, officials said.

Earlier this week, officials raised concerns about the combination of strong winds and low humidity in the coming days that could trigger fire weather conditions, local KOTA TV reported.

As part of the efforts to prevent untoward incidents, officials announced that the following trails in the Black Elk Wilderness Area will remain closed until further notice: #2, #3, #4, #8, #9N and #9S, local KEVN reported.

Meanwhile, two heat records were broken Tuesday in parts of Sioux Falls, the National Weather Service (NWS) in Sioux Falls said. Sioux City broke the previous record of 74 degrees when it hit 75 degrees Tuesday. Sioux Falls logged a record high of 78 degrees to beat the previous record of 73 degrees.
