Toronto officially records its rainiest month ever
It's official. Tuesday's storms bumped Toronto into record-setting territory for its rainiest month ever
Slow-moving, scattered storms on Tuesday provided just enough rain for Toronto's Pearson International Airport to record its rainiest month on record -- beating the previous record by two millimetres.
Only two weeks after a series of training storms caused major flooding across southern Ontario, Tuesday's disturbance ushered in a very muggy air mass, increasing the threat of flooding across the region, once again.

Toronto and the rest of southern Ontario have seen more than its fair share of rain this July, as an anomalous amount of atmospheric moisture has been funneled into the province.
The month started off with the remnants of Hurricane Beryl sweeping into the region, bringing widespread torrential rains and winds.
Only a week later, on July 16, Toronto saw 97.8 mm of rain fall, marking the fifth rainiest day on record, and making meteorologists believe that this could end up being the new rainiest month on record for the region.
On Tuesday, Toronto's Pearson airport needed less than six millimetres of rain to bring its rainiest month on record, and the slow-moving disturbance brought just that.
Toronto saw 7.4 mm fall, bringing the monthly total to 215.4 mm, higher than the previous record set in October 1954 when 213.8 mm of precipitation fell with impacts from Hurricane Hazel.
DON'T MISS: Flood insurance isn't guaranteed, and the type you have can vary
While last week's storm dumped just 30 mm of rain, prompting DVP flooding and Lake Shore Road closures, this storm managed to miss the downtown core and avoid further flooding.
So far this summer, from June to July 30, Pearson airport has received 329.5 mm of rain. The rainiest summer ever recorded saw 396.2 mm in 2008. Currently, Toronto's sitting in fifth spot, with a month of the season still left to go.

Editor's note: July 2013 could have seen more rain than what's recorded in the current database. Further investigation to these rainfall totals are underway, and could impact current record readings.
