Debby's rainy impacts to be felt in Eastern Canada this weekend

Canadians in Eastern Canada will be feeling Debby's tropical impacts this weekend

Tropical Storm Debby made landfall over Florida on Monday morning as a Category 1 hurricane, dropping between 200 and over 400 mm of rain over the state.

Debby quickly weakened back into a tropical storm on Monday afternoon and is now stalling over Carolinas this week before it is predicted to move northward into Eastern Canada.

Historic rainfall and catastrophic flooding are possible in parts of Georgia and over the Carolinas this week as Debby sluggishly moves up the East Coast due to decreased upper-level air movement. Up to 380 mm of rain is possible before a trough over southern Ontario is expected to give Debby the boost it needs to make its way northward late this week and into the weekend.

Collision course to Canada late in the week

Once Debby gains back its momentum, folks in eastern Ontario and southern Quebec could be feeling the tropical impacts starting Friday night until Sunday. 

Debby's time spent inland will serve to weaken the storm, as it will be largely cut off from its warm oceanic fuel. By the time it starts moving again, it is expected to regress into a tropical depression.

Previous forecasts predicted Debby would likely veer back into the Atlantic. However, now models are suggesting the storm's track will remain inland. This is great news for Atlantic Canada, who will be escaping the brunt of the heavy rainfall.

This far out, it is hard for forecasters to know for sure what Debby's exact path is going to be, as well as what impacts it will bring.

The greater threats are expected to be seen in Quebec and eastern Ontario. Forecasters are expecting significant rainfall (50+ mm) and above-normal surf to impact the region at the very least.

Localized flooding from the heavy rains will also definitely be something to look out for over the weekend.

Folks in southern Quebec and eastern Ontario should be keeping an eye on local alerts later this week, as well as keeping up-to-date on the forecasts, as Debby's track and impacts will continue to be monitored.
