‘Heavy Rain’ Hits Toronto as Severe Thunderstorm Warning Remains in Effect
Toronto and large parts of southern Ontario could experience severe thunderstorms throughout Tuesday as a powerful storm system moves across the region.
Environment Canada has issued a yellow severe thunderstorm watch for most affected areas. The storms may produce heavy rainfall, damaging wind gusts and large hail ranging from the size of a quarter to a ping-pong ball.
Rainfall Could Exceed 50 Millimetres
Areas affected by repeated thunderstorms could receive more than 50 millimetres of rain. Environment Canada said the greatest risk of damaging winds is expected in southwestern Ontario, although isolated cases of large hail are also possible.
Wind gusts may reach between 90 and 110 kilometres per hour. These conditions could lead to local power outages and damage to roofs, fences, tree branches and temporary shelters.
The storm system is expected to remain active into Tuesday evening.
Flooding Risk Across Toronto Region
The Toronto and Region Conservation Authority warned that heavy rainfall over a short period could cause water levels in local rivers and streams to rise quickly.
Large volumes of runoff may enter river systems and potentially cause flooding. The agency advised residents to treat all rivers, streams and shorelines within its jurisdiction as dangerous because water levels and currents could change rapidly.
Saturated Ground May Increase Runoff
TRCA watersheds had already received between five and 10 millimetres of rainfall on Tuesday morning before the main storm arrived.
The ground is partially saturated, reducing its ability to absorb additional rain. This could increase surface runoff and contribute to faster-moving water and overflowing rivers.
Residents Advised to Follow Weather Alerts
Environment Canada is urging residents across Toronto and southern Ontario to continue monitoring official weather alerts and forecasts as conditions may change quickly.
People should remain cautious near waterways, secure loose outdoor objects and prepare for possible power interruptions.
Severe thunderstorms could bring heavy rain, hail, destructive winds and flooding risks to Toronto and southern Ontario through Tuesday evening. Residents should avoid rivers and shorelines, stay informed through official alerts and take precautions to protect their homes and property.
