Toronto is bracing for a significant weather event, with Environment Canada issuing warnings for both rainfall and freezing rain throughout Sunday. The agency forecasts between 20 and 40 millimetres of rain, potentially leading to localized flooding, and a risk of icy conditions due to freezing rain beginning near noon.
Rainfall and Freezing Rain Warnings
A yellow rainfall warning is in effect for Toronto, with the possibility of heavy rainfall at times. The frozen ground is expected to limit absorption, increasing the risk of runoff. Simultaneously, a yellow warning for freezing rain has been issued, anticipating ice accretion of 2 to 5 millimetres on surfaces.
Environment Canada advises caution for those travelling on foot or by vehicle, noting that icy surfaces may be difficult to detect. The warnings extend to Oakville, Burlington, and Mississauga. Residents are also advised to clear storm drains and avoid low-lying areas, rivers, creeks, and culverts.
Travel Disruptions
The weather is already impacting air travel. As of Sunday, 11 per cent of departing flights and 25 per cent of arriving flights at Toronto Pearson International Airport are delayed, with 3 per cent of departures and 7 per cent of arrivals cancelled. Billy Bishop Toronto City Airport has cancelled eight Porter flights and delayed twelve.
Porter Airlines stated they are adding flights where possible to accommodate passengers affected by the conditions.
Looking Ahead
While the rain is expected to ease Monday morning, Environment Canada warns of strong winds, with gusts reaching 70 to 80 km/h. These winds, associated with a strong cold front, could pose a risk to areas affected by ice accretion. Local utility outages and damage to structures are possible, and residents are advised to secure loose objects.
Sunday’s forecast for Toronto includes cloud cover, a high of 2 C (feeling like -8 C with wind chill), and wind gusts up to 40km/h.
