Some "slight strengthening" is possible over the next day or two, the NOAA said.
As of 5 a.m. EDT, Ophelia, which isn't now a threat to any land, was centered about 785 miles (1,265 kilometers) southwest of the Azores and moving southeast near 6 mph (9 kph). However, the west coast could see gusts of up to 70mph when Ophelia hits.
The Met Office: "Ophelia will no longer be a hurricane, but will most likely still be a detailed low pressure system bringing strong winds across Northern Ireland and western parts of the United Kingdom".
The US National Hurricane Centre has warned it could strengthen over the next day or so. Ophelia remains well away from any landmasses at the present time.
Hurricane Ophelia is expected to move towards Europe in the days ahead, Silverang said.
Ophelia's arrival will coincide with the 30th anniversary of the Great Storm of 1987, which hit southern England overnight on October 15.
The last time so many named storms in a row became hurricanes was in 1893, he said.
The storm tied a record for the most consecutive storms to reach hurricane force, meteorologist Philip Klotzbach of Colorado State University said. This should take the system just south and east of the Azores.
