At least five people have died after Storm Kristin tore through central and northern Portugal, causing flooding, landslides and widespread damage.
The storm, which the government described as an extreme climactic event, left schools shuttered, buildings damaged and travel severely disrupted.
In the coastal city of Figueira da Foz, a Ferris wheel overturned and several vehicles were hit when part of a roof was torn from a building.
Portugal has been hit by a succession of storms in recent days, including one over the weekend in which a man died after his car was swept away in floods.
Heavy rain and wind gusts of up to 150km (95 miles) per hour caused more than 3,000 weather-related incidents across the country, civil protection authorities said. Several people were struck by falling trees or debris.
The strongest winds were recorded at the Monte Real air base in Leiria, where gusts of 178km were recorded before the monitoring equipment was destroyed. Officials said the location was likely the storm's entry point to mainland Portugal.
More than 850,000 people lost power on Wednesday, according to electricity distributor E-Redes.
The civil protection agency (ANEPC) reported that three people had died in the central district of Leiria - one of the worst affected areas.
Transport across Portugal has been severely disrupted, with roads - including the main motorway connecting Lisbon to the north - and railways blocked by debris.
Ten coastal areas were placed under a red weather warning on Wednesday due to dangerous sea conditions, with waves forecast to reach up to 14m (45ft, 11in), according to the Portuguese Institute of the Sea and Atmosphere (IPMA).
Prime Minister Luis Montenegro expressed condolences to the victims' families. He said authorities were assessing the damage and would take whatever measures are necessary.
After crossing Portugal, Storm Kristin moved east into Spain - bringing with it snow, rain and strong winds.
