An intense low pressure system which absorbed the remnants of Tropical Storm Philippe unleashed its fury on Ontario, Quebec and the Maritimes after racing through the Northeastern United States.
Environment Canada reports more than 100 mm of rain (a month’s worth) fell in Ottawa turning some streets into rivers in the National Capital (2017 is now its wettest year ever) and neighbouring Gatineau.
Strong winds gusted to 93 km/h at Ile d’Orleans with rainfall amounts of up to 90 mm across Southern Quebec.
Western New Brunswick felt the brunt of this storm in the Maritimes while Greater Moncton recorded 25 mm of rain and a peak wind gust of 69 km/h.

The coldest shot of winter 2015-16 has enveloped New Brunswick with an early morning low of -21.0 C in Greater Moncton and as frigid as -32 C in central and northern parts of the province.
Wind chills could drop as low as -35 by Monday morning.
The Arctic dome of air has also led Environment Canada to issue extreme cold warnings for much of Ontario, Quebec, Labrador and all of New Brunswick except the Southeast and Fundy coast.
Extreme cold warnings are issued when very cold temperatures or wind chill creates health risks such as frost bite and hypothermia.
