　　Torrential rain and flash floods caused airport delays,  transit stoppages,  apartment evacuations and a few vehicle rescues in the Philadelphia region.  No serious injuries were reported in the wake of the heavy rains that moved through southeast Pennsylvania on Sunday.  The storms caused the closure of the Broad Street subway in Philadelphia, as well as the Southeastern Regional Transportation Authority’s regional railways.  Most trains resumed running by noon.
　　In Upper Darby,  flooding filled the basements and parts of the first floors of four
apartment buildings, officials said.  A supermarket and other businesses in the area were flooded, and cars were flipped on their sides or overturned by the floodwaters.
　　Nearby Darby borough declared a state of emergency and the American Red Cross was helping about 80 families totaling 250 people who were displaced, Mayor Paula Brown said.
　　"Some just got it in their basement, but we have a lot of people who lost everything," Brown said.She said more than 10 feet of water filled the basement and part of the first floor of some residences.
　　About 100 people were spending the night in Upper Darby High School and about 20 at an elementary school in Darby Borough while about 30 were in a North Philadelphia middle school, Red Cross spokeswoman Omoiye Kinney said Sunday night.
　　To make matters worse, water service was soon shut off, making it impossible to wash things or flush toilets.
　　At Philadelphia International Airport, the rain caused delays of about an hour Sunday morning, airport spokesman Mark Pesce said.
　　Some parts of central Pennsylvania reported 3 to 4 inches of rain overnight, with minor flooding along creeks and riverbanks, according to the National Weather Service in State College.
　　Hurricane Floyd destroyed 337 homes and 53 businesses in Darby in September 1999.
