Rio De Janeiro: Two days of near non-stop rain have dumped a month's worth of precipitation on the World Cup city of Natal, leading to a flood alert and raising worries that the deluge could affect the US team's debut match against Ghana.

No deaths or injuries have been reported in the rains, which began early Friday and abated only on Sunday, dumping in 50 hours as much rain as is usually seen in the northeastern Brazilian city during the entire month of June.
