MANILA, Philippines – Accumulated rainfall levels being measured in and around Metro Manila continue to rise as the monsoon rains enhanced by tropical storm Maring (international codename Trami) continue to pour .
Data from the Manila Observatory released Tuesday, August 20, showed total accumulated rainfall from August 18 to 20, in 23 selected weather stations in Metro Manila, Rizal and Cavite, to be nearing the 500-millimeter mark.
In the case of Cavite, the Observatory said a weather station there has exceeded 700 mm — 724 mm to be exact — total accumulated rainfall, with 300 mm recorded on Tuesday alone. The reading was as of 11 am.
As with data from August 19, the Observatory said the areas with the most rainfall recorded was in the southern half of Metro Manila.
Areas in the middle parts of the metropolis have also recorded high amounts of rain.
In the Manila Observatory’s automated weather station located inside the Ateneo de Manila University campus in Loyola Heights, measured total rainfall since August 18 has reached 57% of the average August rainfall (2007-2011).
It is also 40% of the 4-day rainfall recorded during the August 2012 monsoon flooding.
In 3 weather stations in Makati, rainfall levels are already approaching those recorded during the 2012 “Habagat.”
The stations are located in barangays West Rembo and Forbes Park; and the Makati City Hall.
No time for complacency
Despite the seeming lower rainfall levels in the northern parts of the metropolis, the Observatory said residents should not be complacent.
“Please note that rainfall amount totals are different in different locations in Metro Manila… The low rain totals compared to 2012 so far specifically in Quezon City does not mean that this weather system is not serious,” the institution posted on its Facebook page.
The data came from selected weather stations in the National Capital Region (NCR) owned by the Observatory, as well as from Automated Weather Stations (AWS) that are part of the Metro Weather network, managed by the office, and the Makati City AWS Network.
The Metro Weather network, the Observatory said, is a partnership among MO, Chevron, Globe Telecommunications, Ateneo de Manila University, and the Metro Manila Development Authority (MMDA).
The heavy rain brought by the southwest monsoon, enhanced by the presence of tropical storm Maring, has been pouring over large parts of Luzon, particularly Metro Manila, since Sunday.
The city of Manila alone was 60% flooded Tuesday morning, with some places enduring waters rising to as high as 2.1 meters (7 feet), an official with the Metropolitan Manila Development Authority (MMDA) said during a briefing of the National Disaster Risk Reduction & Management Council (NDRRMC).
At Sangley Point in Cavite, 47.5 cm (18.7 inches) of rain fell in the 24 hours to Monday morning, according to PAGASA meteorologist Esperanza Cayanan.
Back in August 7, 2012 — the height of the 2012 “Habagat” — Sangley Point recorded 364.2 mm worth of rain.
Cayanan said this was the same amount as that which normally falls for the entire of August, already one of the wettest months of the year. – Wtith reports from the Agence France-Presse/Rappler.com
