Environment Canada has issued tornado warnings for areas south of Ottawa.
“At 8:13 PM EDT, Environment Canada meteorologists are tracking a severe thunderstorm that is possibly producing a tornado. Damaging winds, large hail and locally intense rainfall are also possible,” the warning says. “A severe thunderstorm capable of producing a tornado is located near Jasper, moving east at 45 km/h.”
Affected areas include Merrickville, Rosedale, Jasper, Newmanville, Kilmarnock, Wolford Chapel, Eastons Corners, Hemlock Corners, Carleys Corner, Snowdons Corners and Bishops Mills.
Tornado warnings are issued when imminent or occurring thunderstorms are likely to produce or are producing tornadoes.
A series of weather watches are in effect across Ottawa and eastern Ontario, as severe storms move through the area.
Severe thunderstorm watches remain in effect for Ottawa, and stretch from Belleville to Cornwall and the Ottawa Valley. A severe thunderstorm warning was issued for Ottawa shortly before 2:30 p.m. but was called off at about 5:30 p.m. as a weather system moved through the region.
Environment Canada says the conditions continue to be “favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain.”
Conditions are expected to continue through the evening.
The weather statement warns areas could see “torrential downpours with 50 mm (of rain) falling within an hour” and wind gusts up to 110 km/h.
“The main threats will be strong winds, torrential downpours and hail. There is also a risk of a tornado today, especially towards the Ottawa River Valley,” the weather agency said.
“Heavy downpours can cause flash floods and water pooling on roads. Large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles.”
A severe thunderstorm warning remains in effect for Prescott-Russell and parts of western Quebec.
