Helena Storm

During February 1 and 2 there was a worsening of the state of the sea in mainland Portugal due to the passage of storm Helena. This storm, originated by the propagation of a low pressure in the North Atlantic, generated a strong West ripple.

The observation network of the Hydrographic Institute recorded in its buoys the passage of storm Helena. On February 1st, there was a significant height of 9.6m (at 20:00) and a maximum height of 16.4m (at 17:00). A significant height of 8.9m and 14.3m was observed in the Coastal Nazaré buoy. The storm was also felt in the Sines coastal buoy which recorded a significant height of 7.2m (20:00) and maximum height of 11.1m (22:30).
