The likelihood that Hurricane Ophelia will affect Portugal's mid-Atlantic Azores Islands has risen to 60 percent, the Azores Meteorological Forecasts and Monitoring Center announced on Thursday.

Ophelia is the 10th consecutive Atlantic tropical storm to strengthen into a hurricane this year.
Ahead of the heavy wind and rain Hurricane Ophelia will bring with it, temperatures are set to reach 20 degrees over the weekend.
