Six people died and two were missing in the Tuscan city of Livorno after heavy rain hit the city early today, causing floods, the city's mayor said.

Between midnight and 2am more than 250 millimetres (10 inches) of rain hit the city, causing several streams to overflow, the city of Livorno said on its website, citing several casualties.

"The emergency is not over," the administration said on the website.

"Livorno has never been so devastated by bad weather," the mayor of Livorno, Filippo Nogarin, said in a video posted on Twitter, adding the weather forecasts did not suggest a cloudburst so violent in central Italy.

Heavy rain has also hit Rome, where Mayor Virginia Raggi asked citizens to stay home. A Serie A match between Italian soccer clubs Lazio and AC Milan began a hour later because of the bad weather.
