Although not consistent across the board, localized flooding was reported in both Brampton and Barrie over the weekend with 120+mm of rain falling and even some radar estimates in excess of 150mm locally. Between Saturday and Sunday, up to 250+ mm of rain was recorded in some places just north of the Greater Toronto Area (GTA), while others saw next to nothing. “These storms can be so localized, but we’re in for a disaster when they track the GTA like they have,” says Tyler Hamilton, meteorologist at The Weather Network. “Just like on July 8, 2013, when we had over 130mm of rain just east of Pearson International Airport.” MUST SEE: Recalling the historically poor commute when the GTA flooded in 2013 High moisture in the atmosphere, light winds aloft, and lake breeze boundaries are the ingredients to watch for, especially with storms that die as they shift and move over urban areas. “Then it’s a billion-dollar disaster,” says Hamilton.

Monday was no different in terms of thunderstorm risk and locally heavy rain, with more rain and flash flooding being recorded. Thunderstorms that broke through Monday afternoon were again slow, which kept the threat of heavy rain in the same area longer than normal. Rain warnings were in effect into the evening hours for the Halton and Hamilton areas, with an area of severe thunderstorms moving from Horby to north Burlington. Almost 50mm of rain fell in a short period of time. The chance for showers and thunderstorms will continue into Tuesday, though mainly for the eastern parts of the greater Toronto area and through Quebec City.
