Local authorities put Portugal's capital, Lisbon, on high alert on Wednesday evening and urged people to stay indoors as heavy rains killed at least one person, washed cars away and flooded several buildings.
Portuguese weather agency IPMA placed Lisbon as well as the neighbouring district of Santarem and the southern Algarve region on a "red" weather warning due to intense rainfall and strong winds, which are expected to continue until Friday.
In Lisbon, the Civil Protection authority has reported hundreds of incidents, from flooded streets, train stations, a theatre and even a hospital. Authorities have had to shut roads and tunnels.
