Up to 100 millimeters of rain could fall during Ironman Triathlon: Environment Canada

Environment Canada forecasts heavy rain Sunday evening for eastern Ontario, western Quebec

Athletes competing in the Ironman Triathlon in Ottawa could be in for a wet race day after Environment Canada issued yellow-level rainfall warnings across eastern Ontario and western Quebec on Sunday morning.

The weather agency wrote that between 50 and 100 millimetres of rain could fall on Sunday, with the heaviest rain expected in the evening.

The rainwater could pool on roads and in low-lying areas, causing property damage, Environment Canada added.

As of 9:30 a.m. on Sunday, the warning included all of eastern Ontario, including Ottawa, Pembroke, Cornwall, Kingston and Belleville, as well as Western Quebec, including Gatineau, Val des Monts, La Pêche and continuing north.

The Cataraqui Region Conservation Authority, which monitors the watershed between Greater Napanee and Brockville, issued a water safety statement Sunday asking the public to be cautious along watercourses, but said widespread flooding in the area is not expected.
