July 10 update: Storm remnants bring rainfall warnings in Ontario, Quebec

A since-downgraded hurricane that claimed several lives and left a wake of destruction in its path is forecast to strike parts of Canada this week as a tropical storm.

Then-hurricane Beryl wreaked havoc in parts of the Caribbean, Mexico and Texas. It was downgraded from a Category 1 hurricane to a post-tropical cyclone Tuesday morning.

Now classified as a weakened tropical depression, it's expected to head northeast from Texas, eventually reaching parts of Canada.

Here’s where Environment Canada says Beryl’s impact is forecast to be felt.

Ontario

As of Tuesday, Beryl is set to reach Ontario and Quebec on Wednesday and Thursday, with rain and a risk of thunderstorms in the forecast, according to Environment Canada.

Areas in eastern Ontario, including Toronto and the GTA, are under a special weather warning. Environment Canada warns that while it is still difficult to pinpoint the exact track of the system, rainfall amounts could surpass 50 millimetres in some locations, with “torrential downpours†possible at times.

Additionally, special weather statements have been issued for Ottawa, where heavy rains are expected to begin Wednesday morning before ending on Thursday.

The heaviest rain in the Ottawa area will remain in the southern region.

 

Some parts of the province can expect rain to begin as early Tuesday, and heavy rainfall could reach 20 to 40 millimetres per hour, the weather agency said.

The province has since put Toronto and surrounding areas , as it expects to see torrential downpours begin overnight into Wednesday, and end Thursday.

While strong winds are often associated with major storms, the weather advisory said winds are only expected to reach about 20 km/h overnight and 30 km/h on Wednesday.

At the same time, some parts of Ontario, including Toronto, Burlington and Hamilton, are experiencing heat waves. Daily highs are past the 30-degree mark in many areas, while humidex values are in the range of 35 to 38.

Environment Canada said a cooler airmass is expected to arrive Tuesday night.

Quebec

When what's left of Beryl hits Quebec, areas including Gatineau, Montreal and Laval could receive 40 to 80 millimetres of rain and moderate winds beginning late Wednesday and into Thursday.

On Tuesday morning, Environment Canada issued a severe thunderstorm watch for Quebec areas including Alma, Apica Mountain area and La Tuque. Numerous other areas have since been added to the list, placing almost every region in Quebec under a rainfall or severe thunderstorm watch, or special weather statement.

The forecast shows that severe thunderstorms could produce strong wind gusts and heavy rain.

Atlantic Canada

Special weather statements are in effect for areas of New Brunswick, with potentially significant weather expected to begin on Wednesday, as remnants of Beryl make their way through Atlantic Canada.

Environment Canada is advising residents to prepare for significant rainfall in most areas of New Brunswick on Wednesday night into Friday, stating that tropical moisture from the storm is expected to feed into the “slow-moving and somewhat disorganized system.â€

Come Thursday, the system will make its way to P.E.I., bringing with it the potential for significant rainfall into Friday.

At the same time, some areas of the island, Nova Scotia, and Newfoundland and Labrador are facing an unrelated heat warning. Humidex values could make temperatures feel as warm as 37 to 39 Tuesday through Wednesday.

Areas of Newfoundland and Labrador, including Cartwright to Black Tickle, Eagle River, and Norman Bay to Lodge Bay are under severe thunderstorm watches, unrelated to Beryl, until midnight.

Environment Canada says severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce some combination of large hail, damaging winds or torrential rainfall.
