Currently classified as a Tropical Storm, Leslie is expected to become a hurricane in two days time as it heads towards Madeira, or midway between the Azores and the Canary Islands, late on Thursday before heading to west-southwest Europe this coming weekend.
Potential exists for landfall in Portugal or even Ireland on Sunday. The computer modelling will become more accurate as time goes by, but Leslie is being monitored and warnings soon may need to be issued by Portugal's weather service and Civil Defence authority.
