RAPID CITY – The National Weather Service in Rapid City has issued a red flag warning for Tuesday, Feb. 17, as critical fire weather conditions settle over western South Dakota.
The warning is in effect from 11 a.m. until 6 p.m. for much of the region, including the city and surrounding Pennington County. Forecasters expect a combination of strong westerly winds, very low relative humidity, and dry surface fuels to create a high risk for rapid fire spread.
Winds are projected to remain sustained between 25 and 35 mph, with some gusts potentially reaching up to 60 mph. These powerful gusts, paired with humidity levels dropping as low as 13 percent, mean that any spark could quickly evolve into a dangerous wildfire.
“The combination of gusty winds and low relative humidity will produce critical fire weather conditions,” the National Weather Service stated in its urgent fire weather message.
The warning comes as fire crews continue to monitor recent activity in the area. Earlier this month, the Silver Mountain Fire burned 67 acres south of Rockerville, and firefighters are currently working toward full containment on the 58-acre Grey Rocks Fire near Custer.
Local officials are urging residents to take immediate precautions to protect the community. Recommended safety measures include:
- Postponing all outdoor burning.
- Ensuring cigarettes are never tossed from a vehicle.
- Avoiding driving or parking vehicles on dry grass, as exhaust systems can ignite the vegetation.
The grassland fire danger index is expected to reach the extreme category this afternoon. While a cold front is forecast to move through the area tonight, it may bring stronger winds before any potential precipitation arrives.
