The Extreme Weather Centre is open — full list of bus cancellations and school closures in the GTA can be found here.
Both a snowfall warning and flood warning are in effect and some GTA schools are closing for the day as Toronto experiences a weather rollercoaster.
Environment Canada is calling for snow and freezing rain after the significant rain that fell overnight and into Thursday morning. The rainfall made for a very wet morning commute and the drive home is expected to be snowy as temperatures drop.
The Toronto and Region Conservation Authority (TRCA) upgraded to a flood warning on Thursday morning asking residents to “exercise extreme caution around all river and bodies of water.”
“The water levels in some of TRCA’s watercourses are rising steadily and have yet to peak in all of TRCA’s watersheds, specifically in the Humber River and Don River,” says the TRCA. “With the additional forecast rainfall water levels may continue to rise.”
The TRCA is also asking drivers to avoid low-lying areas and underpasses.
The Long Branch GO station in Etobicoke was temporarily closed in the morning due to significant flooding but has since reopened.

The snow, which will be heavy at times, will begin Thursday afternoon and continue through until Friday morning with between 15 to 25 cm of accumulation possible.
“Precipitation will begin as rain [Wednesday] evening and transition to snow Thursday afternoon. Freezing rain and ice pellets are also possible Thursday morning and afternoon,” Environment Canada said in a statement.
“Rapidly accumulating snow could make travel difficult over some locations. Visibility may be suddenly reduced at times in heavy snow.”
The City of Toronto says its salt trucks are ready and will be deployed as soon as the rain changes to freezing rain. Plows will be deployed as soon as snow accumulation reaches 2.5 cm on expressways, five cm on major roads and eight cm on local roads. Sidewalk and bike lane plows will be deployed at two cm of snow accumulation.
The chilly temperatures will return on Friday with a high near -7 C.
