Fierce thunderstorms sweep Montreal & Ottawa

Flooding in Orleans this afternoon. (Ottawa Citizen)

Lines of heavy storms passed through eastern Ontario and southern Quebec late this afternoon and this evening. The storms crossed Montreal during the supper hour knocking out power to thousands of homes with severe lightning and wind gusts to 76km/h at Dorval. I was attempting to install my moms A/C unit as the storms hit LaSalle. The winds kicked up huge plumes of dust from the parking area and the lightning was intense. I managed to install the A/C but sadly left my camera in the car and missed out on awesome lightning. Numerous trees were toppled including one that fell on a house in western Laval sparking a fire. The storms were generated by 32C heat and high humidity that prevailed today in Montreal and Ottawa.

Across eastern Ontario the storms had rotation with several tornadoes sighted. Environment Canada is investigating. Damage was widespread in the Ottawa Valley and in Gatineau regions. Several roofs were torn from buildings in the valley and a church steeple collapsed. Over 90mm of rain fell in Orleans east of Ottawa in less than 1 hour producing widespread flash flooding. Hail was also reported in the region. Tonight more storms are flaring up west of Cornwall and the threat for more severe weather is possible overnight.
