Tornado researchers now say three tornadoes hit Windsor-Essex during heavy storms a week ago.
The third twister touched down in Cottam, Ont., around 10:45 p.m., the Northern Tornadoes Project, based at Western University, said in a blog post Thursday.
The researchers previously found tornadoes touched down in west Windsor and Tecumseh. The storm brought power outages and caused extensive flooding in Essex County.
They said the Cottam twister, rated at EF-1, caused damage to barns and homes, as well as trees, crops and power poles.
