Rainy forecast brings flooding concerns

It will be a grey day with overcast skies and rain slowly building from the northeast, according to CBC meteorologist Brennan Allen.

"Temperatures will be cool today, with most seeing highs in the mid to high single digits and easterly winds between 20 and 30 kilometres per hour," Allen said.

"Total rainfall accumulations by tomorrow morning at daybreak will be the highest in western and southwestern New Brunswick where we can expect 15 to 25 millimetres of rain — giving some flooding concerns."

Overnight lows will drop to the low single digits everywhere except in southwestern New Brunswick, where southerly winds will drive temperatures up to 10 C by Tuesday morning.

"Tuesday will continue to see rainy weather and cloudy skies with the heaviest additional rainfall totals coming from Tuesday morning to Tuesday mid-afternoon," said Allen.

"Additional rainfall accumulations up to 25 millimetres is likely, continuing to raise flooding concerns, particularly in New Brunswick."

Temperatures will be much warmer on Tuesday, reaching into the mid-teens, as a warm front pushes north.

Clearing is expected along with near normal temperatures on Wednesday.
