MANILA - Tropical storm Ondoy brought at least 410 millimeters of rain on Saturday, breaking the worst rainfall record in Quezon City set in 1967.

Philippine Atmospheric Geophysical and Astronomical Service Administration (PAGASA) administrator Frisco Nilo said that from 8 am to 5 pm on September 26, the weather bureau recorded 410 millimeters of rain.

This rainfall level is more than the 391 millimeters of recorded rainfall of Quezon City for the whole month of September 2009, Nilo said at a National Disaster Coordinating Council (NDCC) press briefing Sunday morning at Camp Aguinaldo.

Nilo said this unusual level of rainfall was a sign of climate change.

"Itong mga bagay na ito ay isa sa mga manifestations ng climate change," Nilo said.

PAGASA spokesman Nathaniel Cruz said the 341 millimeters of rain registered in Quezon City from 8 am to 2 pm on Saturday  broke the 331 millimeter worst rainfall record in Quezon City set in June 9, 1967.

Meanwhile, Cruz said PAGASA expects tropical storm Ondoy to be out of the Philippine area of responsibility by late Sunday or Monday.

As of 5 am, Cruz said Ondoy was already in the South China Sea but still within the Philippine area of responsibility.

The strength of Ondoy's winds had gone up from 85 kilometers per hour to 95 kph.  It was moving west northwest, traveling at a speed of 24 kph.

Cruz said Ondoy will continue to enhance the southwest monsoon, but overall, PAGASA expects the weather to improve.
