On the morning of Sunday, 20 July 2025, the coastal city of Savona in Liguria, Italy (44.31°N, 8.48°E) experienced an intense and heavy rainfall event that led to significant local flooding. Between approximately 07:30 UTC (± 5 minutes) and 09:00 UTC, the area recorded a total precipitation of 137.4 mm over a short duration of just 1.5 hours.
This extreme downpour was documented by multiple sources, including a trained storm spotter, eyewitness reports, detailed damage observations, and photographic and video evidence shared publicly. The event was confirmed by the local meteorological network, MeteoNetwork Pretemp, and classified as a high-quality report (QC1), ensuring the accuracy of the rainfall and impact data.
The heavy rain caused widespread flooding, particularly affecting basements and the ground floors of residential and commercial buildings. Several streets were inundated, disrupting traffic and daily activities. Local news coverage highlighted the severity of the event, showing images of waterlogged areas and emergency responses in action.
Such a rapid accumulation of over 130 mm of rain in under two hours is exceptional for the region and is consistent with increasing instances of intense convective storms linked to climate change. Heavy rainfall events like this pose serious risks in urban areas due to limited drainage capacity and can lead to costly damages and safety hazards.
This incident underscores the importance of robust weather monitoring and early warning systems to mitigate the impacts of sudden floods. It also highlights the growing challenge Mediterranean coastal cities face as climate change contributes to more frequent and intense precipitation events.
