Toronto has pivoted from snowstorms to showers, and with that comes the risk of flooding. 

Temperatures in the city have been pretty balmy over the last few days, and the rain is falling. Environment Canada has issued a special weather statement for today and reports that Toronto could see between 15-25 mm of rain. 

While showers are expected to continue throughout the day, there is also the potential for a thunderstorm, Environment Canada reports, with today’s high set to reach 7 C.

The agency has also issued a special weather statement as temperatures are set to fall, with the potential for the rain transition to snow tonight. 

Strong winds combined with snow and blowing snow may cause poor visibility, and slippery conditions.

As the snow that has accumulated over the past few weeks continues to thaw, city officials are sharing advice on how Torontonians can avoid flooding in their homes.

AVOID FLOODED BASEMENTS

The city says that everyone is at risk of basement flooding, even if it hasn’t happened in the past. Basement floods are most common after heavy rain, or while snow and ice are melting. 

To avoid basement flooding, starting outside of the home, residents should ensure they clear snow, ice and debris from eavestroughs and downspouts, and shovel snow away from building foundations.

It’s also important to ensure that cracks or leaks in walls, floors, windows and foundations are sealed, as well as all window wells.

Making sure that drainage ditches between properties are well maintained, and debris is cleared from nearby roadside grates can help to avoid basement flooding, the city adds.

City staff are available to respond to reports of flooding 24 hours a day, seven days a week. You can report blocked catch basins or road flooding by calling the city’s non-emergency line, 3-1-1.

Toronto also has a Basement Flooding Protection Subsidy that provides up to $3,400 per property. You can find out more about this program here.

WATCH OUT FOR STREETS FLOODING 

Meanwhile, the OPP is warning drivers to be careful while on the roads, and keep an eye out for potential standing water or flooding.

“That rain has nowhere to go because of the frozen ground, which could result in ponding of water in low areas on roadways and areas where you’re traveling,” OPP Sergeant Kerry Schmidt says in a video posted to X, adding that drivers should be aware of the risks this poses.

This includes hydroplaning, which can lead to a loss of control of your vehicle and the ability to hit the brakes. Additionally, Schmidt advises drivers to be cautious with pooling water, as it’s difficult to determine how deep it is. 

“You could be going into an area that is very deep which could overwhelm your vehicle,” he explained. “Or there may be potholes or other dangers under the water that you’re not prepared for.”

Rain and mist coming off the roads can also cause reduced visibility for drivers.
