A severe thunderstorm brought downpours and high winds to the Ottawa Valley and the nation’s capital, reducing visibility on roads and forcing people to take cover.
Environment Canada said its meteorologists tracked a severe thunderstorm heading to the capital that had the potential to produce a tornado in the Petawawa and Pembroke area. According to the weather agency, the damaging winds were strong enough that large hail and intensified local rainfall were a concern.
In the most severely impacted areas, damage to roofs, fences and trees was possible with wind gusts reaching 90 km/h.
“This is a dangerous and potentially life-threatening situation,” the government body said.
It was due to a cold front moving through the province on Thursday afternoon.
Environment Canada was encouraging those in the area to take cover immediately if the weather changes abruptly. If people see a funnel cloud or hear roaring, they should seek shelter.
“Go indoors to a room on the lowest floor, away from outside walls and windows, such as a basement, bathroom, stairwell or interior closet,” Environment Canada said. “As a last resort, lie in a low spot and protect your head from flying debris.”
In the nation’s capital, possible wind gusts were forecasted up to 100 km/h and torrential rain upwards of 50 millimetres was expected.
Although the weather agency focused on the valley, it was possible that a tornado developed over the city.
It warned that utility outages were possible, and damage to property and trees is also possible. Heavy rain will reduce visibility.
