The torrential downpour, which at one point dumped more than 90 millimetres of rain in just half an hour, led to the fire brigade being called out 45 times to help flood-hit citizens.
Roads and garages were flooded amid landslides, fallen trees and great inconvenience to residents.
In the villages of Villa Potenza and Sforzacosta, some people were evacuated from the lower floors of buildings.
Other areas in Marche were also affected, in the provinces of Ancona, Fano and Fermo.
The mayor of Amandola near Fermo said the town had suffered “enormous damage”.
Elsewhere, the mayor and president of the Province of Macerata, Sandro Parcaroli, said emergency services were remaining vigilant and undertaking general reconnaissance.
“Fortunately no one was hurt, but it was scary because of how it rained and the damage in the two hamlets is different...,” he said.
“In Sforzacosta, the Narducci ditch flooded, and according to the locals it hasn’t happened since 1960.
“The level of the stream has risen by 5-6 metres, flooding houses, garages and gardens.”
Parcaroli said an elderly person and a family with three children had to be evacuated, and a local school had been closed as a precaution.
He said the downpour was quite extraordinary.
“Impressive drops were coming down from the sky and I had to take refuge in a garage. It was impossible to stand in that rain,” he said.
The water bomb follows catastrophic flooding in neighbouring Emilia Romagna that killed 15 people and caused billions of euros in damage to property, infrastructure and crops last month.
