Around 65 mm (2.56 inches) of rainfall was recorded in under one hour on Elba Island, Italy, on August 20, triggering flash floods that inundated streets and disrupted transportation in the town of Portoferraio.
The intense convective system responsible for the downpour formed rapidly, leading to overflowing drainage systems and road closures across the island.
Multiple reports called it record-breaking rainfall event. However, no rainfall records were broken during this event. While the hourly total was high, it remained below Italy’s historical record thresholds, which exceed 700 mm (28 inches) in 12 hours in some regions. Informal social media reports citing higher totals were not confirmed by meteorological agencies.

Orange alerts were issued for Veneto, Lombardy, Emilia‑Romagna, Liguria, and Tuscany, with yellow alerts for adjacent areas. In Tuscany’s Grosseto province, emergency services rescued three individuals trapped in a flooded underpass. Public buildings and parks were temporarily closed in Milan due to water accumulation and safety risks.
According to the Italian Air Force Meteorological Service (Aeronautica Militare), atmospheric instability was driven by moist air interacting with residual frontal systems over the Tyrrhenian and Ligurian seas. A return to more stable conditions is forecast over the next 24–48 hours.
