National weather services placed fifteen mainland districts under a yellow warning for inland snowfall and increased coastal swell, with outlets warning of travel disruption and hazardous maritime conditions. Forecasters expect snow inland and rough seas along the coast that may affect ferries, coastal roads and port operations. Travellers and mariners should monitor local forecasts and services; note the yellow warning (aviso amarelo) indicates potential danger but not the highest alert level.
Fifteen districts under yellow snow and coastal swell warnings
Friday, 16 January 2026AI summary
Context & Explainers
Aviso amarelo (yellow warning) is the second level in Portugal's weather-alert system issued by the Instituto Português do Mar e da Atmosfera (IPMA) to signal potentially dangerous conditions like heavy snow or rough seas. When districts are under aviso amarelo, expect travel disruption and take precautions—drivers, boaters and coastal residents in the affected areas should be especially alert.
A yellow warning (aviso amarelo) from IPMA signals potentially dangerous weather conditions (the lowest of three levels: yellow, orange, red) that may cause local disruption. For expats it means be alert—expect slower travel and take common‑sense precautions—but it is not usually an immediate emergency level.
