A short but exceptionally violent thunderstorm swept across Forlì in Emilia-Romagna on Friday, August 21, producing destructive straight-line winds strong enough to move and overturn light aircraft at the city’s Luigi Ridolfi Airport.
The most intense phase struck shortly after 14:00 local time. Winds exceeded 100 km/h (62 mph) as torrential rain rapidly swept across the city, with local reports indicating peak gusts around 120 km/h (75 mph).
At Forlì Airport, the force of the wind displaced three light aircraft. Two small planes overturned, while firefighters were called to secure the aircraft and make the apron safe. No injuries were reported.

The airport was temporarily closed as emergency crews dealt with the damage. Part of the roof covering at the arrivals terminal was also torn away during the storm.
A Short-Lived but Destructive Storm
The most violent conditions lasted only around 15 minutes, but the damage extended well beyond the airport.

Trees and large branches were brought down across Forlì, some landing on parked vehicles and blocking more than a dozen major roads. Power infrastructure was also damaged, causing temporary blackouts. Two people had to be assisted after a tree fell onto their vehicles, although neither was injured.
The thunderstorms continued east toward Ravenna, producing further tree damage and disruption as the convective system crossed Romagna.
What Could Flip an Aircraft?
The extreme winds were associated with a powerful thunderstorm downdraft.
Inside an intense storm, precipitation-loaded and cooled air can accelerate rapidly toward the ground. When this descending air reaches the surface, it spreads outward at high speed, producing a downburst and potentially destructive straight-line winds.
This can be particularly dangerous at airports. Light aircraft have relatively low mass but large wings and aerodynamic surfaces, making them vulnerable to sudden extreme crosswinds when parked or moving slowly on the ground.
The Forlì episode demonstrates how a thunderstorm does not need to produce a tornado to generate violent localized wind damage. A sufficiently powerful downburst can produce winds well above 100 km/h and cause significant destruction within only minutes.
