Debby remnants to soak parts of eastern Ontario, Quebec into the weekend
Significant rainfall from Debby's remnants will soak parts of eastern Ontario and southern Quebec through Saturday
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 has been stalling over Carolinas before making its northward move into Eastern Canada.

Historic rainfall and flooding has been targeting parts of Georgia and over the Carolinas this week as Debby sluggishly moves up the East Coast due to decreased upper-level air movement.
The Carolinas, Georgia, and Florida have all declared states of emergencies in the wake of the storm, which has claimed at least six lives due to its flooding rains.
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 overnight Thursday and lasting through Saturday.
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.
Folks in southern Quebec and eastern Ontario, however, should be keeping an eye on local alerts, as well as keeping up-to-date on the forecasts.
Showers and thunderstorms begin to develop Thursday
Showers and thunderstorms will develop over eastern Ontario Thursday afternoon, persisting through the evening and into the overnight hours.
The afternoon storms will track northeast into southern Quebec by Thursday evening and through the overnight.
Friday is when the stormy, tropical weather will really start to rain down over the region, though.
By Friday morning, showers and thunderstorms will become widespread over eastern Ontario and southern Quebec.
Folks can expect moderate to heavy rains to persist throughout the day, with the tropical air mass bringing the most atmospheric moisture the region has seen so far this year. This also means intense downpours are likely.
The rain will finish off strong on Friday night, bringing some of the heaviest downpours of the day to extreme eastern Ontario and southern Quebec.
Rain continues into Saturday before tapering off
Localized flooding from the heavy rains will definitely be something to look out for during the next few days, as a widespread 50-100 mm of rain is likely. Some areas could see a localized 75-100+ mm, but where exactly this will be is uncertain.
DON'T MISS: A stalled hurricane can produce disastrous flash flooding
The majority of the rainfall, including the heaviest downpours, will be wrapped up across eastern Ontario, as well as throughout the Montreal and Quebec City areas by Saturday morning.
The heavy rains will shift eastward into eastern Quebec and the Saguenay region, while southern Quebec will see scattered showers tapering off through the afternoon.
