Heavy rains in South Florida caused flash flooding and prompted a rare "flash flood emergency" warning for Miami and surrounding areas. Over 20 inches of rain fell in some areas since Tuesday. Streets were flooded with stalled vehicles, flights were delayed at major airports, and the Florida Panthers NHL team's travel to Stanley Cup games was also delayed. A disorganized storm system was moving across Florida from the Gulf of Mexico, which coincided with the beginning of an expectedly active hurricane season. The disturbance, which has not yet become a cyclone, has a slight chance of developing into a tropical system after crossing Florida and moving into the Atlantic Ocean.
