Portugal has since Wednesday been affected by the Armand depression, with strong winds, heavy rain and rough seas.
In a statement, the IPMA states that this depression, which is associated with a mass of hot and humid air, with a high content of water vapour, affected mainland Portugal on Wednesday and Thursday and is expected to continue until today, although with less impact due to its displacement to the north-northeast.
