Heavy rain on 15 November sent water, mud, stones and debris from the slopes onto the SS163 Amalfitana at Tordigliano, forcing the road to close. According to Positano News, the flow covered the carriageway and left the route impassable.
The closed section links Positano with Piano di Sorrento and the Sorrento Peninsula. According to Il Fatto Quotidiano, the obstruction left Positano unreachable from the Sorrento side.
ANAS staff were at the site, alongside local civil-protection and municipal personnel, according to Positano News. Firefighters and Carabinieri were also present, Il Fatto Quotidiano reported.
The material on the road included mud, debris and boulders. According to Il Mattino, heavy rain carried water, mud, rock and other material down onto the SS163 between the Sorrento Peninsula and Positano, prompting the closure to traffic.
Local reports pointed to recent fires and the loss of vegetation on the slopes as factors increasing runoff and erosion risk. That connection is a journalistic assessment; no independent engineering finding has been reported.
No reopening time, controlled-passage arrangement or detour plan has been announced. The full extent of any damage to the road itself has not been documented.
