Ophelia became a hurricane late Wednesday, the 10th named storm in a row to reach that status, tying a record set more than a century ago.
Ophelia was no threat to the USA but could move near the Azores by the weekend.
"I am not quite sure what to make of it", Dr Klotzbach told Bloomberg. A slow northeast drift is expected tonight and tomorrow, followed by an acceleration toward the east-northeast or northeast.
Late Wednesday, hurricane-force winds extended up to 25 miles from Ophelia's center and tropical-storm-force winds extended up to 70 miles. Forecasters say slight strengthening is possible over the next couple of days.
Analyses like Moses' take place after each hurricane season and can lead to previously unnamed storms to be added, according to The Weather Channel. But the storm is heading east toward the northwest coast of Spain instead of crossing the Atlantic toward the hurricane-ravaged Caribbean.More news: LA-born National Football League owner in pickle with Cowboys players, president

Forecasters say Ophelia has become the 10th hurricane of the 2017 Atlantic season, churning far out at sea and posing no immediate threat to land.
There were no coastal watches or warnings in effect. All of those occurred in August or September, except for Hurricane Fran in October 1973 and Hurricane Alex in January 2016, which made landfall shortly after weakening to a tropical storm.
According to the Met Office, Ireland and the United Kingdom can expect plenty of wind and rain early next week after a weekend when temperatures will be unseasonably high and could reach as high as 20 degrees in places. That's a bit of an unusual track for Atlantic storms.
Only two other named storms have tracked within 200 nautical miles of the northwestern tip of Spain in NOAA's historical record, dating to 1851. Before satellites, it was hard to keep accurate records of Atlantic hurricanes.
