"While post tropical Ophelia will likely bring some direct impacts from wind and heavy rain to portions of these areas, as well as risky marine conditions, given the forecast uncertainty at these time ranges it is too soon to determine the exact magnitude, timing and location of the impacts".
Hurricane Ophelia is crossing the Atlantic Ocean and could bring wet weather and gusts of up to 70mph when it hits Britain's shores. That would keep the center of the storm south of most of the Azores, but close enough that a tropical storm watch or warning might be issued later today.
Ophelia had winds of 90 miles per hour and could maintain that strength for the next day or two, the hurricane center said.
University of Miami hurricane researcher Brian McNoldy says Ophelia is the 10th straight tropical storm to become a hurricane in an Atlantic season. Three Category 4 hurricanes - Harvey, Irma and Maria - made landfall in USA territories, and that has not ever happened on record!
Ophelia is forecast to continue on a northeast to east path for the next few days.
Located in the central Atlantic about 760 miles southwest of the Azores, the hurricane poses no threat to land and would probably be unremarkable if not for its place in the record books.
Hurricane Ophelia is set to batter Britain over the weekend Will Hurricane Ophelia hit Britain?
And those in Ireland and the United Kingdom may have to watch it too. It actually has happened four times (in 1878, 1886, 1893 and 2017), but named storms were much more likely to be hurricanes back in the 1800s because a lack of satellites and other technology meant only the strongest storms and those making landfall would be noticed.
A Met Office statement said: "A spell of very windy weather is likely on Monday in association with ex-Ophelia".
