The bad weather arrived earlier than expected in Genoa and Tigullio where the first interventions by the firefighters were recorded. Arpal issued a yellow alert starting at 10am but heavy rain began to fall already at dawn. More than 100 millimeters of rain are being exceeded in two hours in the Bisagno basin of Genoa. Likewise, 103 millimeters were recorded in one hour in Chiavari. The village of Portofino is isolated due to a landslide on the Aurelia which temporarily interrupted the circulation of vehicles.
Flooding was recorded in Val Polcevera, in via Rossini, in Rivarolo, in Certosa, and in Val Bisagno, in the Staglieno district, and the branch of the underpass of via Milano, towards via Albertazzi, was closed by the local police due to flooding. In Campomorone a tree collapsed on the main road, there were no reports of anyone involved. The electrical activity was very intense: over 37 thousand lightning strikes have fallen on Liguria since the beginning of the phenomena, more than 20 thousand on Genoa alone. Several blackouts have been reported in the Genoese neighborhoods of Levante, Sturla and Vernazzola. The regional civil protection operations room is monitoring the evolution of the situation in the area, but no important critical issues have been reported.
In Genoa and Tigullio, railway traffic slowed down due to a train that was struck by lightning: the Frecciabianca 8601 train which left Genoa and headed for Rome was stopped in Riva Trigoso station due to the fault caused. The passengers were placed on another train to continue their journey. Delays were also reported in Genoa Brignole due to a line fault. "Intercity and regional trains - RFI communicates - can record a longer travel time of up to 80 minutes". In the afternoon, railway traffic in the Genoa hub gradually resumed.
Several flights are departing late from Genoa airport, due to weather conditions. A Ryanair flight, coming from Bucharest, has been diverted to Pisa. Thus a flight coming from Cagliari was diverted to Bologna.
Railway traffic has been suspended in Ventimiglia since late morning, where lightning sent the station's control room into a tailspin, causing the train movement to lose control. The station remained blocked for a long time. The command and safety systems failed and the technicians went to work to try to restore the situation.
There are slowdowns and queues due to flooding along the A12 Genoa-Rome motorway between Chiavari and Recco and between Chiavari and Lavagna.
In Chiavari, the Municipality activated the sirens due to the risk of flooding of the Rupinaro torrent, inviting the population "to follow the self-protection rules and not stop at critical points". And Speiga: "The communication of the alarm phase highlights an imminent high risk situation: in order not to be surprised by uncontrollable situations, deriving from the particular conformation of our territory, it is necessary to immediately abandon the floodable rooms located on the street levels and below the street level, immediately go up to the upper floors, help the elderly, children and people with disabilities to reach a safe place. Find shelter on the upper floors of the buildings, do not travel on bridges, walkways, underpasses and near the embankment, do not go down into the cellars, basements or garages to secure goods or cars".
Two people were rescued from their vehicles, blocked by water in the underpasses: in Chiavari, the Fire Brigade saved the driver of a van who was trapped in via Bixio, while in Lavagna a 70-year-old man was helped out of his car by some passers-by after he had been trapped by the water.
