What to Know
Approximately 15 percent of stores on the mall's lower level experienced some flooding.
Customers are encouraged to call ahead to ensure certain stores are open.
At least one woman had to be rescued from her SUV at King of Prussia Mall Monday after heavy rains flooded a parking garage and portions of the mall itself.
Rain water poured into the mall’s first floor and food court. A spokesperson for the mall estimated that approximately 55 of 450 stores on the lower plaza experienced some flooding, but the extent of damage remains unclear.
"Even of [those stores], we’re not sure who is going to be able to be open," spokesman Mike McGrath said, adding that customers should call ahead before visiting the mall.
Despite some closures, customers continued to pack into the mall, McGrath said. With 2.9 million square feet available for leasing, the King of Prussia Mall is the largest mall in the United States.
Video shared with NBC10 showed water pouring into the food court as customers splashed by.
Outside, cars became stranded in rising water along Allendale Road and even inside the mall's garage. Rescue crews shut down the street as they attempted to remove vehicles and their passengers.
One car was nearly submerged as it drove down the street.
The storms also affected travelers in surrounding areas, and caused several water rescues in Montgomery, Chester and Delaware counties.
Despite the flooding, King of Prussia Mall will operate on normal hours Monday.
