MANILA, Philippines – The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) on Wednesday afternoon raised the rainfall warning signal from green to red over Metro Manila, as it warned of more intense rainfall in most parts of the metropolis.
PAGASA upgraded the green warning signal issued at past 3 p.m. to a red warning signal later in the afternoon as it noted torrential to intense rainfall over much of Metro Manila.
The red warning signal means the public should expect heavy to intense rainfall from 16 mm to 30mm per hour.
PAGASA, which issued a red warning signal at 4:30 p.m. Wednesday, also said residents in high-risk areas should take precautionary measures and watch out for the next warning.
The state weather observed torrential rainfall (30.0-50.0 mm/hr) over Quezon City, Manila and Marikina, heavy to intense rainfall (15.0-30.0 mm/hr) over Pasig, CAMANAVA, Taguig & Pasay while moderate to heavy rainfall (7.5-15.0 mm/hr) over the rest of Metro Manila.
PAGASA added that due to the effect of the series of thunderstorms embedded in the southwest monsoon, expect heavy to intense (15.0-30.0mm/hr) rains with occasional torrential (more than 30.0mm/hr) rains within 2 hours.
The weather agency said that as of 5:45 p.m. a sudden downpour of heavy to torrential rains was experienced during the past 2-3 hours in most parts of Metro Manila and some surrounding areas.
“The rains were caused by the occurence of a series of thunderstorm which is commonly associated with rains of high intensity,” PAGASA said on its twitter account.
In its 5 p.m. advisory, PAGASA said that the southwest monsoon is still affecting Luzon as it is experiencing occasional rain becoming frequent over the western section which may trigger flashfloods and landslides.
The coastal waters in Luzon and Western Visayas will be moderate to rough.
Elsewhere, winds will be light to moderate coming from the south to southwest with slight to moderate seas. (PNA)
