NHC cautioned that ocean swells generated by Hurricane Chris are expected to affect portions of the coasts of North Carolina and the Mid-Atlantic States during the next few days.
Hurricane Chris is expected to make landfall on Newfoundland's Avalon Peninsula late on July 5 as a post-tropical depression.
The storm, though, is still expected to send swells on the North Carolina coast as well as the mid-Atlantic, the network said. It was headed northeast at 22 miles per hour, on track to brush past Canada's easternmost province and then hit Iceland this weekend.
Environment Canada updated its forecast early Thursday morning, with a warning that heavy rain, strong winds, significant waves and storm surges could hit coastal areas of the island on Thursday.
