Irene becomes post-tropical near the U.S./Canadian border - NHC
At 4:00 a.m. British time the centre of post-tropical cyclone Irene was located near about 80 km north of Berlin, New Hampshire and about 165 km south of Quebec City, Quebec.
"The Tropical Storm warnings in effect for Canada will likely be discontinued early Monday," the NHC said.
Irene was downgraded to a tropical storm on Sunday after it swept up the East Coast over the weekend, leaving at least 15 dead, widespread flooding and as many as 3.6 million homes and businesses without electricity.
