The extreme wind blasting around the country due to Storm Emma caused a tornado yesterday afternoon in the Algarve city of Faro, which overturned boats in the local docks and damaged an esplanade.
Authorities have warned similar phenomena could occur elsewhere in the country.
The blustery conditions are expected to last for most of today. By 11pm last night the National Civil Protection Authority had registered 637 weather-related incidents throughout the county.
