Environment Canada issued a severe thunderstorm watch at 7:23 p.m., as conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts, large hail and torrential rain.
Forecasters say hazards include:
– Damaging wind gusts of 100 to 120 km/h.
– Torrential rainfall producing local amounts of 50 to 75 mm over just a few hours.
– Nickel to ping pong ball size hail.
– Risk of tornadoes.
The timing is this evening into the early overnight.
“Thunderstorms developing over Lower Michigan will track into southwestern Ontario this evening,” Environment Canada officials say.
“The primary threats will be damaging wind gusts and torrential rainfall, followed by large hail. Saturated ground may result in an increased likelihood of downed trees in the event of damaging winds. A tornado threat cannot be ruled out this evening.”
Forecasters added fast-moving water across a road can sweep a vehicle away.
“Large hail can damage property and cause injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road,” Environment Canada officials say.
“Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors. Emergency Management Ontario recommends that you take cover immediately if threatening weather approaches.”
