MANILA, Philippines – High rainfall amounts have been recorded in Metro Manila overnight due to non-stop rain, as rainfall accumulated in the past 24 hours approaches levels last seen during tropical storm “Ondoy” in 2009.

As of 6 a.m. Tuesday, August 7, the state weather bureau Pagasa recorded at least 154 millimeters of rain accumulated in 9 hours at their Manila Port Area station. During the same time period, their observation post at the Science Garden in Quezon City has measured 222.6 mm of rain.

Meanwhile, in the 30-hour period beginning Monday midnight, August 6, up to 6:45 a.m. Tuesday, more than 300 mm of rain have accumulated at the Advanced Science & Technology Institute’s rain gauge, according to Dr Mahar Lagmay of Project NOAH.

During Ondoy, the Pagasa Science Garden measured 341 mm of rain in a span of 6 hours, the bureau said.

The southwest monsoon has been continuously bringing rain over parts of Luzon for 9 days, a rare weather occurrence.

“Siyam-siyam,” or non-stop rain for 9 straight days, has not happened in years, Pagasa forecaster Mario Palafox told ABS-CBN News on Monday evening.

It was last experienced back in 1991, after the eruption of Mount Pinatubo, which was blamed for lahar flows at that time, scientist Dr Kevin Rodulfo told ABS-CBN.

More rain is expected during the day, as the southwest monsoon is still prevailing over Luzon and western Visayas, according to Pagasa.

The rest of Visayas and Mindanao, meanwhile, will be partly cloudy to cloudy with isolated to scattered rain or thunderstorms. – Rappler.com
