Environment and Climate Change Canada has issued a rainfall warning for the following areas:

• Metro Montreal - Laval
• Vaudreuil area
• Valleyfield - Beauharnois area
• Mont-Orford - Lake Memphrémagog area
• Sherbrooke area

Rainfall amounts between 40 and 70 millimetres are expected, along with moderate winds. Rainfall amounts could exceed 100 millimetres, and could include thunderstorms.

David Phillips, senior climatologist with Environment and Climate Change Canada, says this system still has a lot of uncertainty. 

"We have seen the system actually move a little further south. So it actually goes south of Montreal, but it is not going to miss Montreal," Phillips says.

"Montreal is clearly going to see the rain from this. It may just not be the amounts that they will see further south and further east, say the Eastern Townships."

"If the system slows down when it enters Canada, that slowing down can be a problem because then it has more time to spread its misery. If it slows down, it's going to pour down more," he noted.

"If the rain falls intensely, it could cause some pooling and ponding and intersections could be flooded and maybe basements."

Localized flooding in low-lying areas is possible.

According to Phillips, Montreal has already seen 30 per cent more rainfall in the last four months.

The rain will bring cooler temperatures but is expected to warm up again by the weekend.

"We will be back into temperature that would be 29 to 31 degrees which is four or five degrees warmer than normal."
