When we could expect torrential rain in the forecast on Wednesday

The remnants of Hurricane Beryl are headed our way and meteorologists are predicting the hurricane could bring torrential rains to southern Ontario.

Environment Canada issued a rainfall warning on Tuesday. The agency said most areas could expect between 40 and 80 mm of rain starting Tuesday night or early Wednesday morning.

“It would certainly be more rain than the amount of rain that would fall in one day for a month,” said Dave Phillips, senior climatologist with Environment Canada.

Heavy rain could begin as early as 4 a.m. in Waterloo Region and continue until noon, according to CTV weather specialist Will Aiello.

According to Environment Canada, precipitation amounts of 20 to 40 mm per hour are sometimes recorded.

Beryl made landfall in Texas on Monday as a Category 1 hurricane, after leaving a trail of destruction across the Caribbean and Mexico, claiming several lives and leaving thousands without power.

Beryl has been downgraded to a post-tropical cyclone, but despite its weakened rotation, the storm is still expected to cause extensive damage, even far from where it first made landfall.

GRCA Warning

Water levels on local waterways are normal for this time of year, but the Grand River Conservation Authority says the additional rainfall could create dangerous conditions.

“We expect things to change quite quickly as well,” explains James Clark, the GRCA’s senior communications and marketing advisor. “The watershed is quite large. It’s about the same size as PEI, basically. So from top to bottom, things can change quite a bit.”

According to the GRCA, low-lying areas, places with poor drainage and urban areas are their greatest concern.

Anyone walking near rivers and streams is advised to take extra care as banks, especially with fast flowing water, can be dangerous. Adults are also asked to keep a close eye on children and pets in these areas.
