The torrential downpour which struck Toronto Tuesday dumped more rain by 2 p.m. than the city typically sees in the entire month of July.

Speaking with CP24, Environment Canada Senior Climatologist Dave Phillips said that while the city might typically see one or two thunderstorms with heavy rain in a month, Tuesday brought three in quick succession.

The first arrived around 8:45 a.m. and it was followed by two more, for a total of three over three hours.

In terms of intensity, Phillips said at one point Toronto saw 30 millimetres of rain over about 30 minutes.

“That is something you’d see in a hurricane,” he said.

The intense rain also reduced visibility “like a blizzard,” he added.

“We had 25 per cent more rain in three hours than we’d have normally in the whole month of July with all the thunderstorms and systems that moved through,” Phillips said.

2:30 p.m.

Within less than four hours, 96 mm of rain poured down between 8:43 a.m. and 12:00 p.m. at Toronto Pearson International Airport, according to Environment Canada data. Of the grand total, 63 mm fell between the latter two hours.

In Toronto’s city centre, the national weather agency reported 87 mm of rain between 9 a.m. and 1:00 p.m. Within just one hour, between 11 a.m. and 12 p.m., almost 44 mm of rain fell.

Mayor Olivia Chow spoke to reporters about the flooding across Toronto this afternoon, confirming that city hall is among the buildings seeing leaks amid the heavy rainfall.

When asked whether the city will review why some roadways, including the Don Valley Parkway, were not closed earlier, Chow responded, “Of course.”

“Anytime there is an emergency, we need to review whether we’ve done everything we can both on the prevention side and the support side when the crisis happens,” she told reporters.
