The Canadian Press reported that officials in several communities fear the flooding could be worse than the record flooding of 2017 that forced thousands from their homes.

“Today is an important day, we’re predicting we’ll reach the water levels reached in 2017 in the next 24 hours and even exceed it,” said Ginette Bellemare, the acting mayor of Trois-Rivieres, Que., about halfway between Montreal and Quebec City.

“For our citizens, it’s a race against time. They must mobilize and protect their property.”

In the Beauce region south of Quebec City, 868 homes were flooded and 94 people had to be evacuated.

About 120 Canadian soldiers were to be deployed in western New Brunswick , Global News reported. Water levels in the Saint John River Basin are expected to rise significantly over the next few days.

Most of Maine is under a flood watch , the Bangor Daily News reported.

“The biggest, immediate issue is the smaller streams which respond quicker than the larger rivers,” NWS Caribou meteorologist Tony Mignone told the newspaper. “There is going to be some flooding in some areas, but the larger rivers have a longer lag time. The problems with those will begin to show over the next day or two.”

The Kennebec River was over its banks Sunday morning in Augusta, Maine.

The Associated Press reported that minor flooding is expected along the Connecticut River in New Hampshire at North Stratford and Dalton. Flooding also is expected from the Saco River at Conway, the Androscoggin River at Gorham and the Pemigewasset at Woodstock.
