Winter weather travel advisory issued for GTA.

Environment Canada has issued a winter weather travel advisory for the Greater Toronto Area ahead of what could be the first snowfall of the year.

The agency says that a cold front expected to arrive in Southern Ontario on Thursday afternoon will cause temperatures to plummet, resulting in some scattered rain showers changing over to flurries.

As a result, the weather agency says that “untreated surfaces could become icy and slippery” and affect the evening commute.

In addition to the winter travel advisory, Environment Canada has also issued a snow squall watch for a number of communities north of the GTA, including Barrie, Collingwood and Innisfil.

Environment Canada is forecasting a high of 9 C for Toronto on Thursday but the temperature is expected to fall to 2 C by later in the afternoon. The temperature will then drop down to -9 C overnight, according to Environment Canada.
