Toronto officially records its rainiest month ever – The Weather Network

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.
