A large tornado was confirmed near Haley and Buffalo, South Dakota, around 7:30 p.m. local time today, according to verified storm tracking data and atmospheric analysis from NOAA’s Storm Prediction Center. The storm, initially documented by storm chaser and meteorologist Reed Timmer, PhD, appears to have formed along a developing supercell thunderstorm system moving through the region.
Emergency officials in Pennington County, where both towns are located, have not yet reported widespread damage or injuries, though power outages and road closures are being assessed. The National Weather Service (NWS) in Rapid City has issued a tornado warning for the area, urging residents to seek shelter immediately if the storm is approaching.
The tornado’s formation coincides with a broader severe weather outbreak across the northern Plains, where atmospheric conditions—including high instability and strong wind shear—have created favorable conditions for tornado development. According to the National Weather Service Aberdeen office, similar storms have been tracked in neighboring states, though this particular tornado stands out due to its size and duration.
What We Know About the Tornado’s Path and Potential Impact
The tornado was initially observed between Haley and Buffalo, two rural communities approximately 15 miles northeast of Rapid City. According to local reports, the storm’s funnel cloud reached heights of up to 2,000 feet, with winds potentially exceeding 100 mph—a threshold that would classify it as a significant tornado. However, the Storm Prediction Center has not yet assigned an official rating (such as EF-1 or higher) pending further damage assessments.
Residents in the path of the storm have shared videos and photographs online, including one widely circulated clip showing the tornado’s rotation and debris cloud. While no confirmed fatalities or major injuries have been reported as of this writing, emergency management officials are urging caution as response teams conduct door-to-door checks in affected areas. The Pennington County Emergency Management has activated its incident command structure to coordinate with local law enforcement and utility providers.
Key Details Confirmed So Far
- Location: Between Haley and Buffalo, South Dakota (~15 miles northeast of Rapid City)
- Time of observation: Approximately 7:30 p.m. MDT (May 25, 2024)
- Storm type: Supercell thunderstorm with confirmed tornado formation
- Current status: Tornado warning remains in effect; storm may continue moving eastward
- Reported impacts: Power outages, road closures, and possible structural damage under assessment
Why This Storm Is Unusual—and What to Watch Next
The tornado’s development is notable for occurring in an area not typically prone to such intense storms. While South Dakota experiences tornadoes annually—particularly in the southeastern region—the western part of the state, including Pennington County, sees fewer high-end tornado events. According to NOAA’s historical climate data, the last significant tornado in this exact corridor was recorded in 2018, though that storm was smaller in scale.
Meteorologists are monitoring whether the storm system will persist or dissipate as it moves toward the Black Hills region. The National Weather Service Rapid City has advised that additional tornadoes or severe wind gusts could accompany the parent thunderstorm, particularly if the system maintains its intensity. Residents in the storm’s projected path—including areas like Hill City and Keystone—are being urged to remain vigilant.
How to Stay Safe During a Tornado Warning
If you are in the path of a confirmed tornado, follow these steps from the Federal Emergency Management Agency (FEMA):
- Seek shelter immediately: Move to a basement, storm cellar, or an interior room on the lowest level of a sturdy building.
- Avoid windows: Do not open windows or doors to “equalize pressure.”
- Use protective gear: Wear a helmet if available and cover yourself with a mattress or heavy blankets.
- Stay informed: Monitor local weather alerts via NOAA Weather Radio or a trusted weather app.
Emergency Response and Next Steps
Local authorities, including the Pennington County Sheriff’s Office, have begun assessing damage and assisting residents. The South Dakota Emergency Management Division is coordinating with state and federal agencies to provide support if needed. As of now, no major highways (such as I-90) appear to be directly impacted, though secondary roads may require closure for safety.
The National Weather Service will conduct a post-storm survey to determine the tornado’s official rating (EF-Scale) and document any damage. This process typically takes 24–48 hours. In the meantime, residents are advised to:
- Check on neighbors, especially elderly or vulnerable individuals.
- Avoid downed power lines and report hazards to local authorities.
- Prepare for possible power outages by having flashlights, batteries, and emergency supplies on hand.
For those affected by the storm, the American Red Cross has opened a disaster assistance line at 1-800-RED-CROSS (1-800-733-2767) for support with shelter, food, and recovery resources.
