All told, we’re looking at widespread rainfall totals of 75-100 mm throughout southern Quebec. Some areas may see storm totals of up to 125 mm by the time precipitation finally ends on Monday.

Given all the rain we’ve had of late, watch for ponding and localized flooding in vulnerable areas.

Remember, never try to drive across a flooded roadway. It’s impossible to tell how deep the water is until it’s too late. Sometimes the road is washed out beneath floodwaters. It takes a surprisingly small amount of moving water to lift up a vehicle and carry it away.

Sunny and warm conditions will spread over southern Quebec by Tuesday, with the warmth and humidity lingering into Wednesday before unsettled conditions arrive with another cold front.
