The forecast for the state of the sea points to a considerable worsening of weather conditions and sea unrest on the west coast of mainland Portugal from this morning until 18:00 pm on Thursday, January 19, announced the National Maritime Authority and the Marine.
Although, as can be seen in the figure below, the storm is more significant in the center and north of the country, the south will also be affected by strong waves at sea.
Thus, the sea wave will be characterized by a wave coming from the northwest quadrant, with a significant height that can reach eight meters and a maximum height of 15 meters, with an average period varying between 13 and 15 seconds. Winds are expected from the northwest quadrant, with an average intensity of up to 75km/h and gusts of up to 135km/h.
For its part, the Portuguese Institute of the Sea and the Atmosphere (IPMA) has placed the south coast of the Algarve under an orange warning, starting at 18 pm tomorrow, January 00, and until 17 pm the following day, due to the forecast of northwest with 15 to 00 meters of significant height, reaching a maximum height of 5 to 6 meters.
In the case of Costa Alentejana, on the coast of the district of Beja, northwest waves of 4 to 5 meters are forecast today and tomorrow (yellow warning), then increasing to northwest waves of 5 to 6 meters of significant height, possibly reach a maximum height of 10 to 12 meters, which leads the IPMA to place this coastal strip under Orange warning.
Taking this forecast into account, the National Maritime Authority and the Navy recommend, in particular to the fishing and recreational boating community at sea, the return to the nearest harbor and the adoption of precautionary measures.
They also recommend reinforcing the mooring and surveillance of moored and anchored vessels and also advise that "seafarers maintain a permanent state of vigilance and monitor the evolution of the meteorological situation, through the navigation warnings and the meteorological forecast of the Portuguese Institute of the Sea and of the Atmosphere (IPMA), as well as other information made available by the Port Authority on access conditions to ports, avoiding going out to sea until conditions improve».
The population in general is advised against «walking along the coastline and on the beaches, as well as the practice of activities in areas exposed to sea turmoil or affected by the surf».
In particular, «access and stay close to the cliffs and cliffs must be avoided, and it is essential that you adopt a preventive posture, not exposing yourself unnecessarily to risk».
If there is an absolute need to travel to the coastline, you must remain vigilant, always bearing in mind that under these conditions the sea can easily reach apparently safe areas.
