On September 26, Typhoon Ketsana (called "Ondoy" in the Phillippines)  created an intense downpour of rain over the central Phillippines, almost directly over the capital city of Manila.     In 24 hours, Ketsana poured almost 18 inches (455 mm) of rain over the region, causing flooding, landslides, and the loss of hundreds of lives.    Nearly thirteen-and-a-half inches (343 mm) fell over Manila in just six hours.

The Manila Observatory created a Typhoon Ondoy page, which features a Giovanni-generated animation of Ketsana's accumulated rainfall as the storm passed over the Phillippines.   The intense rains over Manila can be clearly seen in the animation.

After inundating the Phillippines, Typhoon Ketsana moved west over the South China Sea and made landfall in Vietnam, causing more fatal flooding in Vietnam and Cambodia.
