The hurricane was moving toward the northeast at 10 miles per hour (17 kph), the NHC said.
Chris is the second hurricane of the 2018 Atlantic hurricane season, after Beryl. Hurricane Chris is unlikely to strike land, though NHC forecasters say it will become a "powerful extratropical cyclone" on its way to Newfoundland, bringing risky conditions all the same.
The area could be hit by heavy rain, strong winds and waves with storm surge along parts of the coast, the centre said. The National Hurricane Center gauges its redevelopment odds at 50% within the next five days.
On its current path, Chris would pass over or near the Avalon Peninsula in southeastern Newfoundland later Thursday or early Friday and weaken on a path toward Iceland and perhaps Ireland.
