Speaking to the Lusa agency, a source said that, between 10:00 and 12:00, "there was a peak of occurrences, 34, currently the only critical area being the tunnel on Avenida João XXI, which is closed to traffic".

"Floods were recorded all over the city, especially in the riverside area of Pedrouços, the North-South axis near Avenida de Ceuta and Estrada de Chelas", said the official.

The district of Lisbon was under a yellow warning from the Portuguese Institute of the Sea and the Atmosphere (IPMA), between 10:00 am and 11:00 am today due to the forecast of precipitation, sometimes heavy, occasionally accompanied by thunderstorms.

The IPMA later extended this warning until 12:00.
