Ophelia is the 10th hurricane of the 2017 Atlantic season.
It is now located 745 miles southwest of the Azores, but as it gains more speed by the end of the week, it could head northeast toward the south of Azores.
"I am not quite sure what to make of it", Dr Klotzbach told Bloomberg.
Tropical storm Ophelia strengthened to the status of a Category 1 hurricane Wednesday and is now heading toward the coast of Ireland. It is also expected to make a gradual turn to the northeast starting Thursday night.
The hurricane's maximum sustained winds early Thursday were near 85 miles per hour (140 kph) with some slight strengthening possible over the next day or two.
Slight strengthening is possible over the next day or two, forecasters said. "Hurricane-force winds extend outward up to 25 miles [35 km] from the center and tropical-storm-force winds extend outward up to 70 miles [110 km]".
After bringing storm surge flooding and power outages to the U.S. Gulf Coast, the remnants of Nate will bring heavy rain and gusty winds to the Northeast Monday.
Hurricane Ophelia is moving northeastwards far out over the Atlantic Ocean.
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.
Previously, only two tropical cyclones have struck the coasts of Spain and Portugal in the past - a transitioning hurricane in October 1842 and Hurricane Vince, as a tropical depression, in October 2005. Days later, Hurricane Irma hit the Caribbean and Florida and was the strongest observed storm in the Atlantic since Wilma.
