System brings snow, ice and flooding to Ontario

Staff writers

December 1, 2011 — A moisture filled system has brought everything from rain to freezing rain and snow to parts of Ontario this week.

A large storm system affecting eastern Canada has left its mark in parts of Ontario.

First, there was record rainfall. By the early afternoon hours on Tuesday, Toronto's Pearson International Airport had already shattered its daily rainfall record of 20 mm set back in 2005. Over 50 mm of rain fell across the city and that was enough to reduce visibility on the roads.

In the Windsor area however, the bigger issue was flooding as close to 90 mm of rain fell throughout the day. Emergency officials say they responded to nearly 250 calls from residents reporting flooded basements, street flooding and flooded yards.

In the nearby town of Tecumseh, residents were told not to flush their toilets to avoid putting more water in the sewage system.

In northern central and northern sections of Ontario, temperatures were cool enough for freezing rain on Tuesday. That led to poor driving conditions and widespread power outages.

About 30,000 customers in cottage country were without power by the early morning hours on Wednesday as ice piled up on hydro lines. School buses in North Bay, Sturgeon Falls, Mattawa, Parry Sound, Huntsville and the Muskoka district were also cancelled for a second day in a row on Wednesday because of the freezing rain.

Wrap-around moisture from the same system was bringing snowfall to the Greater Toronto Area Wednesday afternoon. A centimetre of snow was recorded at Pearson International, but it didn't stick around long.

The system continued to track eastward into southern Quebec and the Maritimes where rain and freezing rain were reported.

“Conditions will clear across Ontario on Thursday before a weak disturbance moves through during the evening and overnight hours,” says Brian Dillon, a meteorologist at The Weather Network. “Parts of northern Ontario could see an additional five centimetres of snow and the city of Toronto could pick up a couple of centimetres before it tapers on Friday. It won't be a big snow, but it could cause slick roads.”

Motorists are encouraged to prepare for changing and dangerous conditions and to adjust their driving habits accordingly.
