Montreal hit by tornadoes

Environment Canada confirms Monday’s funnel clouds were twisters

The two funnel clouds that tore through Montreal Monday, tearing limbs from trees in Ste-Anne-de-Bellevue and Mascouche and knocking out power with winds up to 90 kilometres an hour were actually F0 tornadoes, the lowest intensity tornadoes on the Fujita scale. Environment Canada made the confirmation, says the system has now moved on and that weather should be calm and cool until the weekend.
