According to a statement, AMN warns that the sea swell will be characterised by "waves coming from the western quadrant, with a significant height that can reach between four meters and seven metres".

Taking this information into account, the AMN, together with the Portuguese Navy, warns "the entire maritime community" and "the general population" about the precautions they should take, whether when preparing to go to sea, when at sea or in coastal areas:

  • Reinforce mooring and maintain close surveillance of moored and anchored vessels;
  • Avoid walks along the seafront or in areas exposed to rough seas, such as cliffs or beaches, to avoid being surprised by a wave;
  • Do not engage in recreational fishing, especially near cliffs and cliff areas frequently hit by breaking waves, always bearing in mind that in these conditions the sea can easily reach apparently safe areas.
