Flooding expected tonight south of city

Flooding continued this weekend along Lake Champlain and the Richelieu River.

Another round of heavy rain is expected across southern Quebec, eastern Ontario and northern New England tonight. A Flood Watch is in effect south of Montreal across the Richelieu Valley and into northern Vermont and New York. Sharp rises on the Richelieu River occurred over the weekend as southerly winds pushed waters from Lake Champlain northward on into eastern shorelines. Several lakefront homes and basements were flooded. Quebec Civil Protection is fearful that tonight's rain, which could be in the order of 30-40mm, will only increase the flood risk. Low pressure over the Midwest with a warm front will approach the region by Tuesday morning with heavy rain along the front and a few thunderstorms. The rain will continue most of the day on Tuesday. The entire week will be unsettled with showers and thunderstorms. Until the front lifts north of Montreal temperatures will remain cooler than normal with northeast winds. Once the front clears the region, temperatures will warm to near 20C by mid week with mild overnight lows around 8C.
