It formed in the Central Atlantic Ocean about 875 miles (1,405 km) west-southwest of the Azores islands.
There are now no coastal watches or warnings in effect with the storm far out at sea.
It now has maximum sustained winds of 50mph, but will reach at least 74mph as it approaches western Europe. But the storm seems to be heading east towards the coast of Spain instead of crossing the Atlantic towards the hurricane-ravaged Caribbean.
The hurricane center expects Ophelia to top out as a Category 1 hurricane with 80 miles per hour winds before becoming a post-tropical or extra-tropical system toward the end of the 5-day forecast period.
National Hurricane Center (NHC) forecaster Stewart noted on October 10 at 1:44 p.m. EDT "Convective banding has continued to become better defined since the previous advisory, and an eye-like feature has developed in the center of the convection". That has not happened since 1893, according to McNoldy.
Pressure mounts on Catalan separatists after unity rallies
Some chanted "Don't be fooled, Catalonia is Spain " and called for Catalan president Carles Puigdemont to go to prison. The demonstrators defend the respect for independence in law-making in Catalonia and also unity across Spain.

Forecasters say Ophelia is expected to become a hurricane by Thursday.
Ophelia is forecast to track northeast through Monday.
The other disclaimer about tropical cyclones before satellites were routinely used to examine the entire tropical Atlantic Basin in 1966 is that some tropical storms - even hurricanes - may have been missed that could have influenced any streaks, especially in the 19th century. Then Ophelia will curve north towards Ireland's west coast as a post-tropical storm.
