Severe storms struck southern Italy overnight between October 9 and 10, 2026, causing flash flooding, overflowing rivers and landslides across Sicily, Calabria, Puglia and Campania, according to Italian news agency ANSA and broadcaster Sky TG24. The system followed an orange-level weather alert issued a day earlier by Italy's national Civil Protection Department.
Where the damage was worst
The most critical situation was reported on Lipari, the largest of Sicily's Aeolian Islands, where two torrents known as Ponte and Valle overflowed during the night, Sky TG24 reported. Dozens of homes were invaded by water, and several cars became stuck in the area around the port. Mud and debris carried by the torrents reached the beaches and the sea, and the Canneto district required post-flood restoration work. Firefighters assisted motorists stranded by the floodwater.
In Trapani, in western Sicily, waterspouts displaced about ten families and injured nine people, ANSA reported. Authorities in the nearby towns of Marsala and Petrosino were also assessing damage from the same weather system.
In Calabria, the mayor of Melito di Porto Salvo, near Reggio Calabria, described the downpour as "a water bomb," according to ANSA, with vehicles swept toward the sea and walls collapsing.
Further north, heavy rain flooded the crypt of the Basilica of San Nicola in Bari, Puglia, and schools were closed in the Salento area as the orange alert remained active across south-central Puglia. In Naples, a sinkhole roughly five meters in diameter opened in the Materdei neighborhood and swallowed a passing car, though ANSA said the driver was unharmed; a centuries-old pine tree also collapsed at Cardarelli Hospital. The coastal towns of Anzio and Nettuno, in Lazio, requested disaster declarations.
The official alert
According to the Civil Protection Department's own statement published on protezionecivile.gov.it, an orange alert was assessed for October 10 covering Sicily and sectors of Calabria, Puglia and Campania, with forecasts of scattered to widespread rainfall, mainly in the form of showers or thunderstorms, accompanied by intense downpours, strong wind gusts, localized hail and frequent lightning. A separate yellow alert covered Abruzzo, Molise, Basilicata and parts of Umbria, Lazio, Calabria, Campania and Puglia on the same day.

Government response
ANSA reported that Civil Protection Minister Nello Musumeci stayed in contact with Lipari's mayor and the prefect of Messina as the situation developed. Undersecretary Lucia Borgonzoni said cultural heritage sites were being monitored, with damage recorded at an archaeological site in the province of Lecce.
Why the storms formed
Meteorologist Lorenzo Tedici, cited by ANSA, attributed the intensity of the storms to elevated sea-surface temperatures in the Mediterranean, which he said had accumulated excess heat from the summer months and were feeding the atmospheric instability behind the downpours.
What remains unknown
As of the sources reviewed, ANSA reported nine injuries in Trapani from the waterspouts, with no deaths reported in Sicily or Calabria. No total damage cost estimate had been published for the affected regions, and authorities in several towns, including Marsala, Petrosino and Lipari, were still assessing the extent of the destruction.
