The National Weather Service confirmed Riley County saw an EF-2 tornado Thursday evening, placing the storm over the county from 5:13 p.m. to 5:23 p.m. with peak winds of 120 mph. No injuries or deaths were reported after the tornado, which damaged a home on Union Road and left other structural damage along the east side of the county.
The confirmation gives an official timeline to a fast-moving storm that prompted emergency calls and local response across Riley County. In the City of Riley, dispatch activated outdoor warning sirens after residents reported seeing a tornado, even though the National Weather Service had not yet issued a tornado warning. Riley County Emergency Management said some residents later reported they did not hear the siren, and officials worked with the maintenance company to track down a mechanical problem in the system.
That gap between the reported sighting and the formal warning added urgency to a storm that moved quickly through northeast Kansas on Thursday, June 4. Laurie Harrison thanked residents for calling in the tornado sighting and said the storm appeared very quickly, with no tornado watch or thunderstorm warning in effect when it formed. Several counties in the region saw severe weather that evening, but the verified damage in Riley County centered on the Union Road home and the other structures hit along the county’s east side.
Roads that had been closed because of flooding were reopened, and several people were rescued from stranded vehicles in the Manhattan area Thursday night. Repairs to the siren system are expected to be completed next week. For residents trying to understand what happened, the official answer is now clear: Riley County took a brief but destructive EF-2 hit, and the bigger question is whether the warning system will be fully ready before the next storm arrives.
