More rain equals more flooding for southern Quebec

Flooding concerns continue to mount tonight across southern Quebec and eastern Ontario, with more rain in the forecast. A state of emergency has been declared in Rigaud, northwest of Montreal, as a result of flooding from the Ottawa and Rigaud Rivers. Melting snow upstream, combined with heavy rain during the month of April, have pushed the Ottawa River and its tributaries to near record levels. In Rigaud, evacuations have been ordered, with numerous roads impassable. All that water continues to flow towards Montreal and Laval. Water levels along the rivers surrounding Montreal, as well as on Lake of Two Mountains and Lac Saint Louis, are producing flooding. Greatest concern at this time are low-lying areas in Laval, as well as Sainte-Anne-de-Bellevue, Pierrefonds, Senneville and Ile Bizard. Minor flooding is also occurring along the shoreline of L'Ile Perrot. The Town of Hudson is also watching Lake of Two Mountains which is expected to rise by several centimetres into this weekend. Sandbags are being made available by that municipality.

Southeast of Montreal, Lake Champlain reached flood stage of 100 feet on Tuesday, but has since lowered slightly. Minor flooding is occurring along shore front communities in upstate New York and Vermont, northward into the Richelieu Valley of Quebec. More rain and isolated thunderstorms are in the forecast as low pressure moves from the Great Lakes into eastern Ontario on Friday. Rain will develop early Friday and taper of Saturday. Another 15-20mm is possible for the entire region.
