Violent thunderstorms swept across the Versilia coast of Tuscany on Friday, August 21, producing wind gusts approaching 100 km/h (62 mph) and leaving a trail of damage from Marina di Pietrasanta to Viareggio.
Beach resorts were among the hardest hit. At Tonfano, powerful winds ripped away umbrellas and awnings, overturned sun loungers and even displaced small rescue boats. Damage was also reported around Lido di Camaiore and Viareggio.
Local observations measured gusts above 80 km/h (50 mph) around Forte dei Marmi and Pietrasanta, while reports elsewhere along the coast indicated peak winds approaching 100 km/h (62 mph).
Trees Fall as Storm Hits the Coast
Numerous trees and large branches were brought down by the storm. In Viareggio, a plane tree fell onto parked vehicles near the market area, while fallen pines caused additional damage around Marina di Pietrasanta and Tonfano.
Firefighters and civil protection teams responded to numerous calls, while Pietrasanta activated its municipal operations centre to coordinate the emergency response. No injuries were initially reported in Versilia.

Il maltempo sta provocando gravi disagi in diverse regioni del Nord Italia e in Toscana, con frane, allagamenti, blackout e alberi caduti. In Valcamonica il crollo di un ponte ha imposto la chiusura della statale 42, mentre l’esondazione del torrente Vallaro ha… pic.twitter.com/cBQ034At8b
The storm also created problems farther inland. Landslides isolated the villages of Pomezzana and Le Calde in Stazzema, while fallen trees temporarily blocked several roads.
Some communities also experienced electricity outages as the intense winds affected local infrastructure.
Why Were the Winds So Strong?
The Versilia storm formed during a broader outbreak of severe weather affecting Tuscany and other parts of northern and central Italy after a prolonged period of summer heat.
Very warm, humid air near the surface provided substantial energy for thunderstorms. As a disturbance and colder air arrived higher in the atmosphere, instability increased sharply and allowed powerful convective cells to develop.

In #Toscana, in 12 ore sono stati registrati oltre 23.000 fulmini e circa 6.000 utenze sono rimaste in black out. Venti da record con raffiche fino a 106 km/h sulla costa pisana. pic.twitter.com/A02SUapogL
Within intense thunderstorms, precipitation can help accelerate air downward. When these downdrafts reach the surface, they spread horizontally and can generate sudden bursts of destructive straight-line wind.
Such convective gusts can occur over relatively small areas, explaining why damage can be severe in one coastal community while locations nearby experience considerably weaker conditions.
The Versilia coast is particularly exposed when powerful thunderstorm outflows reach the shoreline, where beach structures such as awnings, umbrellas and lightweight equipment offer little resistance to sudden wind gusts.
The episode formed part of a much broader severe-weather event across Tuscany. In Florence, intense winds brought down trees and construction material, disrupted tram services and injured a woman after she was struck by a falling roof tile. More than 200 firefighter interventions were reported across the Florence area during the wider event.
