The risk for heavy rain has continued to push east prompting a rainfall warning for areas including Cornwall, Kingston and Brockville.
"General rainfall amounts of 25 to 50 mm are expected with some locales within the warned regions receiving 50 to 75 mm," says Environment Canada in the warning. "The heavy rain is expected to taper off later this morning for areas near Lake Ontario, but by early afternoon for regions closer to the Quebec border."
"There is the risk for severe storms and possibly some supercells in northestern Ontario in the Georgian Bay area and eastward towards the Quebec border this afternoon," adds Weather Network meteorologist Monica Vaswani.
Officials warn that heavy downpours can cause flash floods and water pooling on roads and localized flooding in low-lying areas is possible.
WATERSPOUT WATCH ON THE LOWER GREAT LAKES
Conditions are favourable for the development of waterspouts prompting a waterspout watch for the southern Great Lakes.
Swimmers and boaters are advised to monitor the conditions when waterspout advisories are in effect.
Waterspouts are considered to be weak tornadoes over water and they're normally seen in the early fall.
"As the cooler air passes over the warm lakes, it provides the perfect environment for waterspouts to kick up," explains Weather Network meteorologist Brian Dillon.
Although most waterspouts tend to stay over water, they do have the potential to come onshore. It's best to keep a safe distance if you see one develop.
