A weather system from the Great Lakes is currently affecting Southern and Central Quebec. It will give total amounts ranging from 50 to 80 millimetres by the end of the day Friday.

On Saturday and Sunday, a low pressure system currently east of Florida may interact with this first system. Significant rainfall amounts may add to those which will have already fallen from Southern Quebec to the North Shore. At this time, amounts between 20 and 40 millimetres are expected, but could be higher over some regions.

Strong winds are expected all over Quebec on Saturday and Sunday.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Landslides may occur in vulnerable areas such as steep slopes.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports to #meteoqc.
