The intense storm system which spawned swarms of tornadoes in the U.S. Midwest and South gradually shifted a vast supply of energy toward southern Ontario Tuesday. 

Extremely heavy rainfall began to fall over the Greater Toronto Area Tuesday morning -- just in time for the morning rush. 

Rainfall began to intensify throughout the afternoon, which ultimately resulted in the Toronto Pearson International Airport setting a new daily rainfall record.

As of 2:00 p.m. local time, the airport was reporting 22 mm of rainfall. By the early morning hours on Wednesday, 28 mm had fallen.

The previous record was set back in 1964 when 17.5 mm of rain fell.

Tuesday marks day one of a soggy week ahead. 

An additional 10-20 mm of rain is forecast in southern Ontario through Thursday, while parts of eastern Ontario could see up to 50 mm.

"Another area of rain associated with a large disturbance slowly approaching from the U.S. Midwest will affect the regions this afternoon and tonight," said Environment Canada in a special weather statement Wednesday. "The forecast rainfall amounts are below the threshold of 50 mm or more in 24 hours, and currently rainfall warnings are not anticipated."

The Toronto and Region Conservation Authority is warning residents to stay away from rivers and streams, as heavy rainfall will result in higher than normal water levels and flows.
