Flash Flood Potential for Eastern Canada

Very wet pattern shaping up for a large part of eastern Canada through Saturday as tropical moisture originating over the western Caribbean and Gulf of Mexico gets funneled northward just ahead of a front.

The map below indicates the potential rainfall from Thursday through Saturday. So obviously this does not include what has fallen in places earlier today or tonight from the initial wave.

The heaviest rainfall will spread up into the region Thursday through Friday as the tropical moisture gets involved. In addition to the heavy rain there will also be embedded thunderstorms with gusty winds.

The map below shows the approximate timing of the heaviest rainfall...

The result of this event will likely be widespread flash flooding for parts of eastern Ontario and into Quebec.

Behind this system we can expect a period of cool weather with more clouds than sun and some afternoon showers.
