Winter storm to dump heavy snow on Hamilton, Niagara and surrounding regions

A messy mix of winter weather is in the forecast for Hamilton, Niagara Region, Burlington and surrounding areas starting Wednesday afternoon, with Environment Canada warning of heavy snow and freezing rain.

Environment Canada has issued a freezing rain warning and a winter storm watch for southern Ontario, advising of "heavy snow for the afternoon commute, then an ice storm tonight."

In the warning the federal weather agency said people should expect "a prolonged period of freezing rain leading to significant ice build-up in some areas."

Meteorologist Geoff Coulson told CBC Hamilton that the snow storm is the result of a system moving up from the American southwest.

"It certainly looks like it's gonna be quite a significant event for Burlington, Hamilton and Niagara areas," Coulson said. 

"We're likely going to see some notable impacts on the commute home this evening ... with some freezing rain that could continue right into the Thursday morning commute."

The agency said ice accretion of 10 to 20 millimetres is possible. Snow will be heavy at times, mixed with ice pellets or a freezing drizzle. Total amounts could reach five centimetres.

Environment Canada is also forecasting northeasterly winds to gust at speeds of 50 to 70 kilometres per hour with the strongest wind gusts to hit exposed areas downwind of Lake Ontario.

Extensive outages, tree damage likely

The agency warned "extensive outages and tree damage are likely due to the combination of ice accretion and strong winds." 

It also says to beware of highways, roads, parking lots and walkways becoming icy and hazardous. Motorists should slow down while driving on the road, the agency said.

Coulson said due to the number of hours of freezing rain on Wednesday, power outages become more likely as ice coated branches and wires are blown around by the gusty winds. 

"Watch for tail lights ahead and maintain a safe following distance," Environment Canada said. "Beware of branches or electrical wires that could break under the weight of ice."

The City of Hamilton is expected to see temperatures hover between –3 C and –1 C all of Wednesday into Thursday morning.

Prepare for winter storm event

Late Tuesday the City of Brantford issued a statement urging residents to prepare for the cold weather and possible power outages.

The city said residents should ensure emergency kits are up to date with drinking water, flashlight and batteries, food, blankets and a first-aid kit. 

Meanwhile, Brock University urged students and residents to exercise caution when travelling to and from campus.
