The lower level of King of Prussia mall was filled with water after flash flooding rushed through the food court and some of the stores. Schuylkill Expressway at Route 22 near the mall was also affected by the flood. Not too long after, officials were able to clean up the flood damage and get the mall back to normal operations.
King of Prussia is currently open following regular mall hours. Due to weather conditions, some stores may not open or experience delays in opening. Mall employees are encouraged to contact their store manager or corporate offices for store hours.
