A strong thunderstorm caused flash flooding to swamp parts of the University of Louisville's main campus while emergency workers rescued a Kentucky congressman's mother from a creek swollen by heavy rain.

School officials say flood water on Tuesday morning seeped into a handful of campus buildings, including the Chemistry Building, which had water in its basement. The university canceled morning and afternoon classes but evening classes still were expected to be held as scheduled.

The mother of U.S. Rep. John Yarmuth was rescued from a creek after her vehicle was partly submerged in its swift current after a crash. Yarmuth, a Democrat who represents a Louisville-area district, said in a statement that she received minor injuries from the wreck and he thanked rescuers for exceptional efforts in helping her.
