Commander Luís Martins warns that a new episode of an atmospheric river will affect mainland Portugal in the coming days, increasing the risk of falling trees and landslides. Authorities say the greatest danger is to those travelling on roads and urge motorists to be extra vigilant, follow official guidance, consider postponing non-essential journeys and watch for debris, flooded sections and unstable slopes. The warning highlights risks to transport infrastructure and the need for coordinated emergency response and preventative measures.
