Parts of Toronto will see winds of 80, 90 or even 100 kilometres per hour in some instances on Sunday, Environment Canada meteorologists warn.
"Strong southwest wind will develop late Sunday morning or early Sunday afternoon as a cold front moves through southern Ontario," Environment Canada said in a wind warning advisory issued on Saturday evening. "Isolated thunderstorms are possible along this cold front, which may bring localized wind gusts in excess of 100 km/h."
Winds of that strength threaten overhead power lines, idle construction cranes, billboards and other light freestanding structures.
A wind storm in May 2018 killed three people across the GTA, including two arborists in Milton, Ont.
Environment Canada says “widespread power outages are possible.”
On Friday, Hydro One urged its customers to prepare for power outages caused by high winds.
"The company encourages customers to restock their emergency kits ahead of the anticipated weather in case of an extended power outage," Hydro One said in a statement.
They forecast the winds will subside by Sunday evening.
It'll be a mix of sun and cloud on Sunday with a 60 per cent chance of showers. The temperature is expected to climb to a daytime high of 17 C.
Freezing rain and snow are in the forecast for Monday, with a high of 1 C.
