A Sunday afternoon deluge turned roads into rivers in South Jersey, submerging cars and stranding drivers, and set a record for one-day rainfall in Philadelphia.

During a six-hour period from 2 to 8 p.m., 7.38 inches of rain fell at the Philadelphia International Airport, according to the National Weather Service. NWS meteorologist Patrick O'Hara confirmed that the rain total this afternoon set the city's daily record since record tallying began in 1872.

A portion of Terminal A at the airport lost power for a few hours in the early evening and backup generators didn't immediately turn on, according to reports. Airport officials were still working to restore power at 9 p.m., reports said.

And the rain wasn't over just yet.

The heaviest rain passed shortly after nightfall, forecasters said, but flash flood warnings remained in effect until 10:45 p.m. Sunday evening for Philadelphia, southeastern Delaware County, and northwestern parts of Camden, Gloucester and Salem counties in New Jersey.

Late-day flash floods hit Camden, Bellmawr and Paulsboro leading to sporadic road closures, according to police dispatchers and scanner reports. In Gloucester City, a stretch of Route 130 under Route 295 was "completely flooded" and had cars submerged, the Breaking News Network said.

No injuries were reported.

By 7 p.m., the National Weather Service reported minor flooding of the Cooper River.
