In a statement, the Portuguese Institute of the Sea and the Atmosphere (IPMA) indicates that Depression Davide will cause waves from the west/northwest with a significant height of up to 5.5 metres until Sunday morning.

The sea swell will temporarily decrease during Sunday and until mid-afternoon on Monday.

In addition, 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.

Therefore, IPMA (Portuguese Institute of the Sea and the Atmosphere) has 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 affect the Madeira archipelago.

Due to rough seas, IPMA had already issued warnings for the entire Portuguese coast for today and the weekend.

All districts on the Portuguese coast are under a yellow warning until 21:00 today.

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 changing to yellow until 06:00 on Sunday.

Also, due to the swell, the districts of Faro, Setúbal, and Beja are under a yellow warning until 6 PM today and then again between 12 PM on Saturday and 3 AM on Sunday.

The orange warning is issued by IPMA (Portuguese Institute of the Sea and Atmosphere) whenever there is a "moderate to high risk weather situation," and the yellow warning when there is a "risk situation for certain activities dependent" on the weather.

Due to the sea conditions, the maritime 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 subject to restrictions, according to information released on the National Maritime Authority's website.
