In a statement, the two entities ask the general population not to walk or perform activities near the sea, and to avoid accessing and staying near cliffs and cliff areas.

They also ask the fishing community and recreational boaters, who are at sea, to return to the nearest port of shelter and to take precautionary measures, namely to reinforce the mooring and surveillance of vessels and to monitor the evolution of the meteorological situation, avoiding going out to sea until conditions improve.

The AMN justifies that a considerable worsening of weather conditions and sea disturbances is expected on the western coast of mainland Portugal between 12:00 today and 12:00 on Saturday.

“Sea agitation will be characterised by swells coming from the Northwest, with a significant height that could reach eight metres and a maximum height of 14 metres (…). The wind may register an average intensity of up to 65 kilometres per hour (km/h) and gusts of up to 120 km/h, coming from the Northwest quadrant”.

The same worsening is also predicted for the Madeira archipelago, but between 12:00 on Tuesday and 12:00 on Wednesday.
