Southern Ontario is experiencing extreme summer weather, with both intense heat and the threat of heavy rainfall.
Environment and Climate Change Canada (ECCC) says that while some areas could see the current heat wave break on Tuesday, hot and humid conditions may persist into Wednesday in eastern Ontario and the Greater Toronto and Hamilton Area. On Tuesday, humidex values were expected to make temperatures feel above 40 C.
In the meantime, forecasters are warning of heavy rain across the region. Downpours are possible Tuesday afternoon and evening in southern Ontario, including the Greater Toronto Area. ECCC says isolated thunderstorms could develop over much of northern Ontario, while southern Ontario is more likely to see widespread storms.
“Thunderstorms may produce very strong wind and local torrential downpours over southern Ontario, especially late this afternoon and this evening,” the agency said.
Rainfall totals could reach 40 to 60 millimetres in some areas.
