Orange warning: seven districts, waves up to 10m
The Portuguese Institute for Sea and Atmosphere (IPMA) has issued an orange warning for rough seas across seven mainland districts—Porto, Viana do Castelo, Braga, Aveiro, Coimbra, Leiria and Lisbon—in force until 12:00 on Saturday. Swells are expected to be particularly severe in the north‑west, with waves potentially reaching up to 10 metres. The advisory signals a heightened marine hazard; residents, mariners and coastal visitors should heed official guidance and avoid exposed areas.
Update: CNN Portugal confirms IPMA's forecast of waves up to 10 metres and reiterates that the orange warning remains in force until 12:00 on Saturday; authorities advise avoiding exposed coastal and harbour areas until conditions ease.
Update 2: Público and other outlets list the affected districts explicitly and note that Coimbra and Braga have orange warnings in effect until 12:00 while other districts are under yellow warning levels — a staggered schedule responders say reflects local conditions.
IPMA is the Portuguese Institute of the Sea and Atmosphere (Instituto Português do Mar e da Atmosfera), the national agency for weather, marine forecasts and climate monitoring. Residents should watch its forecasts and warnings during storms, heatwaves or cold snaps because IPMA issues official advisories used by services, transport operators and local authorities.
