Environment Canada says it was a thunderstorm fueled by muggy weather, that left a path of destruction behind.
Haldimand County Councillor, Bernie Corbett says, Dunnville has experienced damage like this during winter storms in the past,
but to his knowledge – has never been hit by such a powerful summer thunderstorm.
Dunnville was one of several communities in Southern Ontario hit by the storm including Binbrook and South Hamilton.
It was a storm fueled by the heat and humidity bathing the region and much of the province. Delivering driving rains, whipping up the wind and knocking out the power for several hours.
Matt Ingram takes a look at the damage left behind.
