Up to 45 millimetres of rain could fall in some regions today, which could have dire consequences for riverside communities at risk of flooding.
Rain is expected to continue through Tuesday, according to Environment Canada.
Temperatures are also expected to climb quickly on Monday, to a high of 21 C, and add to water levels with melting snow and ice.
Quebec’s flood forecasting centre says everyone along major rivers in southern Quebec should be prepared for flooding.
Riverside communities remain on high alert, most notably those along the Chaudière River in the Beauce, where ice floes jammed a 1.5 kilometre section of the river at Beauceville and forced water into the town.
A few dozen Beauceville homeowners were issued evacuation notices on Saturday but most refused to leave their homes.
Twenty businesses have also been affected.
Town employees were going door to door to check on residents and have set up an evacuation centre.
High water along the Chaudière also forced around 60 people from their homes in St. Lambert de Lauzon.
Other rivers considered at risk of flooding are:- Mille-Îles River in Laval
- Rivière des Prairies
- Nicolet and Bécancour Rivers in Mauricie
- Saint-François River in the Eastern Townships
- Yamaska River at St-Hyacinthe
- Châteauguay River in MontérégieSuggest a correction
