The swollen Seine peaked Monday at more than four metres above its normal level, leaving a lengthy mop-up job for Parisians after days of rising waters that have put the soggy city on alert.

The river rose to 5.84 metres early Monday, causing continued headaches for commuters as well as people living near its overflowing banks.

The Vigicrues flooding watchdog said the river would stay at its current level throughout the day before beginning to recede Tuesday.

Around 1,500 people have been evacuated from their homes in the greater Paris region, according to police, while a similar number of homes remain without electricity.
