Starting early Monday afternoon, scattered thunderstorm activity could bring the risk of severe weather to parts of Southern Ontario. The Golden Horseshoe and Eastern Ontario regions are particularly susceptible to storm development, with potential threats including heavy rainfall, strong wind gusts, and small hail.
A slight risk of severe weather is in place for the Niagara region, extending into Eastern Ontario along the Lake Ontario shoreline, including areas like Peterborough and Kingston. The primary concerns in these areas are hail up to the size of quarters and wind gusts reaching 90-100 km/h. Additionally, although unlikely, an isolated tornado can't be entirely ruled out.
For the rest of Eastern Ontario and along the Golden Horseshoe, there is an isolated severe threat. However, storm development further to the west is more questionable, potentially limiting the actual impact in these areas.
Moreover, heavy rainfall will be a significant concern with these storms, potentially leading to localized flooding. For more detailed information on the flooding threat, please refer to our dedicated rainfall forecast available here:
