Ondoy's Flood Worst in History PAGASA - MB

The Philippine Atmospheric, Geophysical, and Astronomical Services, Administration (PAGASA) said Saturday that the unexpected flood in Metro Manila was the worst one ever recorded in history. While Dr. Nathaniel Cruz, PAGASA director, said that yesterday's flood was the worst in history, he added that the amount of rainfall dumped yesterday is expected to surpass the 1967 record and this month's average.

Citing PAGASA records, Cruz said that a total 341.3 mm amount of rainfall had been dumped in Quezon City from 8 a.m. to 2 p.m. last Saturday, just six hours following the actual landfall of Tropical Storm "Ondoy" in Central and Southern Luzon provinces. The 24-hour amount of rainfall is expected to overtake the 344 mm level recorded on a 24-hour period on June 7, 1967.

After expecting the tropical cyclone to bring stormy weather in most parts of Luzon until today, the top PAGASA official said the level of rainfall is also expected to even surpass 391.7 mm average rainfall in Quezon City for the entire month of September.

He also explained that Tropical Storm "Ondoy," which was expected to move towards the South China Sea away from the Philippine area of responsibility early this morning, could double or at least increase the amount of rainfall in the next 12 hours.

Cruz added that "Ondoy," which was last spotted over Pampanga province as of 5 p.m. yesterday, also dumped unusually high amounts of rainfall over Bulacan that prompted PAGASA to release 175 cubic meter of water each second from Angat when it reached its critical level at 1 p.m. on Saturday.

"Ondoy" was last spotted over the vicinity of Pampanga while packing maximum winds of 85 kph near the center and a gustiness of 100 kph that prompted PAGASA to raise storm signals in 20 provinces in the regions of Cagayan, Bicol as well as Central and Southern Luzon.
