A minor tornado and a pair of downbursts have been confirmed after a storm rolled across Chatham-Kent late last week.
The Northern Tornadoes Project said three weather events with damaging winds occurred the morning of June 12.
The group said it has confirmed that an EF0 tornado formed in Croton, while two EF0 downbursts occurred in Blenheim and Walpole Island First Nation.
Scattered power outages were reported throughout the day, affecting hundreds of Hydro One and Entegrus customers in the Chatham-Kent area.
According to NTP investigators, a cell tower on Walpole Island was damaged, and a ground survey completed on June 12 showed tree and minor roof damage in the area. The downburst had an estimated maximum wind speed of 130 kilometres an hour with damage found over a limited area of roughly 1.2 kilometres long and 0.5 kilometres wide.
The Blenheim downburst resulted in tree damage and minor damage to homes and fences. That downburst had an estimated maximum wind speed of 125 kilometres an hour with damage found over an area roughly 2.2 kilometres long and up to 0.9 kilometres wide.
The Croton tornado resulted in damage to an outbuilding and crops, although no injuries were reported. The twister had an estimated maximum wind speed of 130 kilometres an hour with a track length of 4.8 kilometres and maximum path width of 150 metres.
The Northern Tornadoes Project, based out of Western University in London, was founded in 2017 to better detect tornadoes across Canada and improve severe and extreme weather understanding.
