Overview
- Environment Canada's special weather statement calls for 15 to 40 millimetres of rain across parts of Ontario, with higher local totals possible in thunderstorms.
- Several rounds of showers and isolated thunderstorms are expected from this evening through Saturday evening.
- Unseasonably mild temperatures will accelerate snowmelt while frozen ground limits absorption, increasing runoff and the chance of localized flooding.
- Officials caution that water may pool on roads and washouts are possible near rivers and creeks, and drivers are urged not to attempt to cross flooded areas.
- Areas northwest of Toronto could see near-zero visibility in dense fog before conditions improve later, and residents are advised to monitor Environment Canada alerts and consult local Conservation Authorities or Ontario.ca/floods for updates.
