Rapid City, SD – Extreme fire danger is expected across Western Fall River County in South Dakota on Thursday and Friday due to strong winds, dry conditions, and low humidity levels. Authorities urge residents to avoid outdoor burning as fire risks reach critical levels.
According to the National Weather Service in Rapid City, southwest winds of 15 to 25 mph with gusts up to 40 mph will develop Thursday, particularly along and south of Interstate 90. Humidity levels are expected to drop to 15-25%, increasing the likelihood of fire spread.
By Friday, a potent low-pressure system will shift winds to the northwest, maintaining very high to extreme fire danger. Dry grasses and organic material create prime conditions for rapid and unpredictable wildfire behavior.
Officials warn that any fire could spread quickly, becoming erratic and difficult to control. The grassland fire danger index is expected to remain in the extreme category, indicating hazardous conditions for outdoor burning.
Residents in affected areas, including Ardmore, Edgemont, Provo, and Rumford, should take precautions to prevent accidental fires. Authorities recommend securing outdoor equipment that could spark, avoiding open flames, and staying informed on local fire conditions.
The fire danger outlook remains critical heading into the weekend. Residents should monitor updates from the National Weather Service and local fire officials for any emergency alerts.
