Remnants of Hurricane Beryl expected to hit Canada, downpours possible

Remnants of Hurricane Beryl expected to hit Canada, downpours possible

Remnants of Hurricane Beryl will impact parts of Canada this week, bringing the risk of localized flooding to some parts of Canada.

Beryl made landfall on the Texas coast early Monday morning as a Category 1 hurricane with dangerous storm surge and strong winds.

“After the storm makes landfall along the Gulf Coast early Monday morning, its remnants will encounter a low pressure system moving across the U.S. and ride the higher-level winds toward the Great Lakes,” said Ross Hull, a Global News meteorologist.

“By the time the remnants of Beryl reach the Great Lakes on Wednesday, it will have transitioned into a more typical low pressure area; the difference, however, will be the tropical moisture it will transport across the border into Canada.”

Hull said there are concerns about heavy rainfall from southern Ontario, through southwestern Quebec and then into parts of the Maritimes, likely New Brunswick.

It is still unclear which specific areas will receive the heaviest rainfall, Hull said.

“But there is a chance of rainfall of 25mm to locally 50+mm, which could lead to localised flooding, especially in urban areas,” he said.

“There will also be enough instability for thunderstorms to form, which could also lead to heavy rain showers.”

In terms of timing, rain is expected in southern Ontario and the Greater Toronto and Hamilton areas on Wednesday morning and into the afternoon.

According to Hull, the impacts will be felt in southwestern Quebec and Montreal from Wednesday afternoon through Thursday morning.

“The heavy rain should clear from southern Ontario on Thursday and from southwestern Quebec and the Maritimes on Friday,” Hull said.

Special weather forecasts issued for most of Southern Ontario, parts of Quebec

Most of Southern Ontario is currently under a special weather warning ahead of the system’s arrival.

“While confidence in the exact path of the weather system is low, these types of systems have historically produced very high rainfall totals in downpours,” Environment Canada said.

“Rainfall warnings may be issued as confidence in the system’s track increases.”

The weather bureau said heavy rain could hit parts of southern Ontario beginning Tuesday night or Wednesday, possibly continuing into Thursday. Hazards include downpours with rainfall amounts of 20 to 40 mm per hour at times, and local rainfall totals “potentially well over 50 mm,” the statement said.

But confidence in the exact course of the system and the amount of rainfall is currently low, the weather agency said.

Parts of southern Quebec, including Montreal, are also under a special weather warning.

According to Environment Canada, heavy rain is expected in the Montreal area starting late Wednesday and continuing through Thursday.

“A total of 40 to 80 millimeters of rain is expected, along with moderate winds,” the weather agency said.

“Heavy rainfall may cause flash flooding and puddles on roads.”

Environment Canada said in its statement in Montreal that there could be “significant impacts” to the afternoon rush hour and encouraged people to modify or postpone non-essential travel.

Beryl strengthened and became a hurricane again on Sunday night, weakening after leaving a path of deadly destruction across parts of Mexico and the Caribbean.

Beryl was the first storm to develop into a Category 5 hurricane in the Atlantic Ocean. The storm claimed at least 11 lives as it moved through the Caribbean on its way to Texas.

The storm has since weakened back to a tropical storm and is expected to become a tropical depression on Tuesday, the U.S. National Weather Service said.
