Public Information Statement National Weather Service Binghamton NY 1003 PM EDT Sun Jun 22 2025 ...NWS Damage Survey Results for Clark Mills Tornado... Rating: EF1 Estimated Peak Wind: 105 mph Path Length /statute/: 2.43 miles Path Width /maximum/: 300 yards Fatalities: 3 Injuries: 0 Start Date: 06/22/2025 Start Time: 03:58 AM EDT Start Location: 1 NNE Clark Mills / Oneida County / NY Start Lat/Lon: 43.0928 / -75.3669 End Date: 06/22/2025 End Time: 04:03 AM EDT End Location: 1 N Clinton / Oneida County / NY End Lat/Lon: 43.0629 / -75.3713 Survey Summary: A deadly pre-dawn tornado spun up at a kink in a line of severe thunderstorms, in Clark Mills of Oneida County NY. Numerous trees were uprooted or snapped, with many of them on structures. 3 homes were sliced or crushed by trees. 2 residents were killed in one of the heavily-damaged homes, and a third fatality occurred on the crushed end of another residence. The tornado quickly became intense while traveling southwest initially, and unfortunately destroyed a historic grist mill along Oriskany Creek. The tornado then became absorbed into the southward motion of the line of thunderstorms, traveling along Kirkland Avenue before ending. While there was this focused corridor of convergent enhanced EF1 tornado damage, other scattered tree damage could be found throughout the area associated with damaging winds up to 70 mph from the line of severe storms. The National Weather Service would like to thank impacted residents for sharing their accounts, as well as Oneida County Emergency Services, Town of Kirkland Department of Highways, New York Office of Emergency Management, and Clark Mills Volunteer Fire Department for their tremendous assistance in conducting this storm survey. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the event and publication in NWS Storm Data.

Rotation occurred in a kink in the line of storms, generating an EF1 tornado from just south of Westmoreland, through the western edge of the Hamilton College Campus, to near Clinton in Oneida County NY. Numerous trees were uprooted or snapped, and a farm sustained significant damage to its silo and outbuildings. Debris from the farm was lofted at least 1000 feet across the field, with some of it impaling the ground as debris missiles. While there was this focused corridor of convergent enhanced EF1 tornado damage, other scattered tree damage could be found throughout the area associated with damaging winds up to 70 mph from the line of severe storms. The National Weather Service would like to thank impacted residents as well as a trained skywarn spotter for sharing their accounts of this tornado. We also thank Oneida County Emergency Services,and the Hamilton College Emergency Manager for their tremendous assistance in completing this survey. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the event and publication in NWS Storm Data.

Addition Information
EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories:
Microburst: A convective downdraft with an affected outflow area of less than 2 1/2 miles wide and peak winds lasting less than 5 minutes. Microbursts may induce dangerous horizontal/vertical wind shears, which can adversely affect aircraft performance and cause property damage.
