Motorists cross a flooded road in Marikina, east of Manila on September 27, 2009, a day after tropical storm Ketsana lashed the area around the capital city. At least 51 people were killed and more than a quarter of a million displaced after tropical storm Ketsana dumped the heaviest rainfall on capital Manila in more than four decades, officials said. Manila and surrounding areas were lashed with heavy rains for nine hours, leading to flash floods that inundated about 80 percent of the capital of more than 12 million inhabitants.
