PHOTOS: Significant flooding shuts down major roads in southern Ontario

It's only Tuesday, but it's already been a rain-soaked week in southern Ontario, with training storms causing flash floods in some communities Monday.

On Sunday, another set of powerful storms whipped through, with rain and wind strong enough to down trees and halt traffic in some places due to near-zero visibility.

On Tuesday, there's another risk of afternoon thunderstorms and reduced visibility. A morning shower added to the already saturated terrain, raising the risk for additional floods and infrastructure damage.

The downpour cemented the day in the history books, making it one of the rainiest days on record at Toronto Pearson airport.

People are reminded to never drive, walk, or ride through flood waters. Fifteen centimetres of standing water, sometimes less, can be enough to cause damage to your engine. At about the 30 centimetre mark, a typical car can being to float -- that means no traction and no steering control, leaving you at the mercy of the current. At 60 centimeters, about two feet, of water, even larger vehicles such as pickup trucks and SUVs are in danger of floating away. As a rule of thumb, don't drive into water that's too deep to see the painted markings on the road.

Here's a closer look at the rain situation in photos:
