Depression Davide will affect the western coast of mainland Portugal from this Friday, December 5th, with strong sea agitation, particularly north of Cabo da Roca, with warnings having already been issued, according to IPMA.
In a statement, the Portuguese Institute of the Sea and Atmosphere (IPMA) indicates that depression Davide will cause waves from the west/northwest of up to 5.5 meters in significant height until Sunday morning.
The sea disturbance will temporarily decrease during the day on Sunday and until mid-afternoon on Monday.
Additionally, persistent and sometimes heavy rain is expected from the end of today until mid-afternoon on Saturday in Minho and Douro Litoral, and in the districts of Aveiro, Vila Real and Viseu.
For this reason, IPMA issued a yellow warning for the districts of Viseu, Porto, Vila Real, Viana do Castelo, Aveiro and Braga, especially in mountainous areas, between 00:00 and 15:00 on Saturday.
The Davide depression will not have any effects on the Madeira archipelago.
Due to the maritime unrest, IPMA had already issued warnings for the entire Portuguese coast for today and the weekend.
All districts on the Portuguese coast are under yellow warning until 9pm today.
The IPMA issued an orange warning for the districts of Porto, Viana do Castelo, Lisbon, Leiria, Aveiro, Coimbra and Braga between 12:00 and 18:00 on Saturday, then turning yellow until 06:00 on Sunday.
Also because of the waves, the districts of Faro, Setúbal and Beja are under yellow warning until 6pm today and then between 12pm on Saturday and 3am on Sunday.
The orange warning is issued by IPMA whenever there is a “moderate to high risk meteorological situation” and the yellow one, when there is a “risk situation for certain activities dependent” on the weather.
Due to the state of the sea, the sea bars of Caminha, Douro, Esposende, Vila Praia de Âncora, Póvoa do Varzim, Vila do Conde and Portinho da Ericeira are closed to all navigation and those of Aveiro, Viana do Castelo and Figueira da Foz are restricted, according to information published on the National Maritime Authority website.
