‘Strong low pressure system’ headed for GTA, more than 40 mm of rain expected

Toronto could see up to 40 millimetres of rainfall tonight and into Thursday morning, Environment Canada says.

The weather agency has placed the entire GTHA under a special weather statement due to a “strong low pressure system.”

It says that there is also the “potential for severe thunderstorms late this evening and overnight.”

CP24 Metrologist Bill Coulter says that the storm is not likely to intensify until around 11 p.m.

Coulter says that once it arrives, residents should expect consistent downpours until 3 a.m. or 4 a.m. with residual rain continuing until around 8 a.m. on Thursday.

He says that the rain should not intensify until the conclusion of the World Cup game slated for Toronto Stadium at 7 p.m.

However, he says that the 43,000 fans attending that match should plan for isolated showers.

“The game will probably be OK with just some light showers but after the game if you are out reveling because your team won or are just in the World Cup spirit and want to keep things going late into the night well you have to keep in mind that heavy downpours with embedded strong thunderstorms are expected from 11:30 p.m. through 3 or 4 a.m. and then we will still see a few lingering showers and thunderstorms until about 8 a.m.,” Coulter says.
