Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km).
The center of the storm was located 315 miles east of Cape Hatteras, N.C., and was moving at 22 mph toward the northeast, the NHC's advisory said Wednesday morning.
Although there are now no coastal watches or warnings in effect, weather officials warned that Hurricane Chris could potentially produce heavy surf and create life-threatening rip-currents along the East Coast in the coming days.
It is expected to weaken to a "strong post-tropical cyclone" on Thursday, according to the National Oceanic and Atmospheric Administration.

The social-media company warned on Wednesday that its crackdown on fake accounts means users will have fewer followers. Some of the losers are among so-called influencers who are paid huge amounts of money to post content on their pages.
Rip currents are possible for beaches from ME to the Carolinas, the National Weather Service said. Chris, which remained a tropical storm for days off the coast of North Carolina, first became a hurricane late Tuesday.
If it does reform, it should stay well off the U.S. East Coast, AccuWeather said.
Southern coastlines of that region can also expect storm surges. By later this week, Chris may bring gusty winds and heavy rain to portions of Atlantic Canada. The storm should start to transition into an extra-tropical but still powerful storm system later Thursday and Thursday night as it approaches the southeast coast of Newfoundland. Maximum sustained winds have increased to near 105 miles per hour, and it will likely continue to strengthen through Wednesday morning.
Wind warnings are in effect for the southeastern half of the Avalon Peninsula, which could see southerly wind gusts up to 100 km/h Thursday evening. "There really is no big option for the track of this storm, it's going to continue to take on that northeasterly direction, picking up speed and weakening".
