A monsoon-like rainstorm has dumped a record amount of rain on Paris, flooding streets, snarling traffic and briefly forcing the closure of metro stations. Sunday's downpour forced about 15 underground railway stations to close due to flooding, three of which remained shuttered early yesterday, Paris transport authority RATP said. The national weather service, Meteo France, said 6.8cm of rain fell in the two-hour storm, dramatically ending days of hot and humid weather. A record-breaking 4.9cm of rain fell in one hour, equivalent to three weeks' rainfall in an average July, the weather agency said. The previous one-hour record for rainfall in Paris was set on July 2, 1995, when 4.7cm was recorded. Heavy rain returned yesterday morning but traffic on the metro was reported to have returned to normal, apart from the three stations that had to be closed.
