Environment Canada issues multiple weather alerts for southern Ontario

Environment Canada has issued multiple weather alerts for southern Ontario, including Waterloo Region, warning of freezing rain, heavy rainfall, strong winds and the potential for snow squalls in some areas.

A freezing rain warning is in effect for much of the region, with ice accretion of two to five millimetres expected on some surfaces. The freezing rain is forecast to begin later Sunday morning and continue into the evening, before changing over to rain as temperatures rise above zero.

Environment Canada said roads and walkways are likely to become icy and slippery, with icy surfaces potentially difficult to detect.

At the same time, a rainfall warning has been issued, with total rain and freezing rain amounts of 30 to 60 millimetres expected, and locally higher amounts possible. Rain is forecast to begin Sunday morning and become heavy at times through the afternoon and evening, before easing overnight.

Officials warn the frozen ground will have a reduced ability to absorb the rainfall, increasing the risk of localized flooding. Some roads may become impassable, and motorists are being advised not to drive through flooded roadways. Residents are also urged to avoid low-lying areas, stay away from rivers, creeks and culverts.

“Police want to remind the motoring public to watch for pooling water on our roadways and highways, and to be very cautious,” said Ontario Provincial Police (OPP) Sgt. Ed Sanchuk in a video posted to X on Sunday. “Please, if you do not need to travel today or tomorrow, please stay home...freezing rain along with snow can create invisible ice, making braking, steering and stopping extremely unpredictable.”

Environment Canada is also warning of strong winds on Monday, with gusts of 70 to 80 kilometres per hour expected. The winds are forecast to develop Monday morning with the passage of a strong cold front and ease by Monday evening as they shift to the northwest.

Areas that receive ice accretion from freezing rain will be particularly vulnerable to damage, with the potential for power outages and damage to roofs, fences, tree branches and other structures. Residents are being advised to secure loose objects.

Meanwhile, parts of Huron and Perth counties — particularly areas closer to Lake Huron — are under a snow squall watch. Environment Canada said lake-effect snow squalls are possible from Monday morning into Tuesday, bringing near-zero visibility in heavy snow and blowing snow.

Wind gusts of 70 per hour or greater expected. Travel may be extremely hazardous, and sudden road closures are possible, the agency warned.

The OPP urges motorists to plan accordingly, slow down and to “pack an ample amount of patience” for travel disruptions.

Closures and on-street parking bans

The City of Cambridge has declared a snow event, imposing an on-street parking ban to allow for snow removal.

City officials said the ban began at 7 a.m. on Sunday and will remain in effect for 24 hours.

Vehicles left on city streets during this time may be ticketed or towed.

“Sidewalks must be cleared within 36 hours following the end of snowfall,” a media release read in part. “Snow should not be shoveled onto the road. Please wait 36 hours after the snow event is over to report a problem area.”

The city said the declaration was made with the intention of ensuring streets remain clear for city snowplows and clean-up crews.

In Wellington County, officials said that both the Aboyne and Fergus libraries will be closed “due to inclement weather.”
