Weather Update: June 17, 2013

PAGASA may raise alert level to orange if rains continue

MANILA (9 p.m. UPDATE) - Heavy rains over Metro Manila on Monday night prompted state weather bureau PAGASA to raise the yellow alert at 8:30 p.m.

Areas covered by the warning are:

Caloocan,
Malabon,
Navotas,

Valenzuela,
Manila,
Pasig,

Pasay,
Taguig,
Makati,

Paranaque,
Las Piñas,
Muntinlupa,

Quezon City (Fairview, Novaliches and Commonwealth), Mandaluyong,
Pateros.

PAGASA said moderate to heavy rainfall fell over these areas for the past hour, and the rains will most likely to continue for the next 3 hours.

Under the heavy rainfall warning system, a yellow warning is raised when the expected rainfall amount is between 7.5 mm to 15 mm within one hour and likely to continue, according to the Palace.

Areas covered by this advisory should be aware of the weather, particularly the threat of flooding in low-lying areas.

An orange alert is raised in areas where rainfall is between 15 mm to 30 mm within one hour.

Flooding is a definite threat in communities under the green alert, according to Manuel Quezon III, undersecretary for the Presidential Communications Development and Strategic Planning Office.

Meanwhile, a red alert is issued when downpours constitute an emergency.

This is raised when observed rainfall is more than 30 mm within one hour or if rainfall has continued for the past three hours and is more than 65 mm, Quezon said in a blog post.

PAGASA weather forecaster Samuel Duran told dzMM that residents of areas covered by the yellow alert should be ready.

"Iyung mga lugar, maging handa na po sila. Iyung floodings, possible na lalo na sa mababang lugar," he explained.

"Usually po, 2-3 hours (ang ulan). Kapag rainfall advisory na po, medyo tatagal," he added.

He said the rainfall alert level might be raised further if heavy rains continue Monday night.

"Maari pong mag-upgrade po tayo ng orange kung lalakas po ang ulan natin. Titignan po natin kung mag-uupgrade po tayo," Duran said.

PAGASA will issue its next advisory at 11 p.m.

The heavy rains spawned floods and caused traffic jams across parts of Metro Manila again early Monday night.

The rains are caused by the southwest monsoon made more intense by tropical depression Emong, according to weather bureau PAGASA.

MMDA CCTV footage along EDSA showed southbound road traffic grinding to a standstill amid the heavy rains.

The MMDA said it deployed rescue teams and rubber boats on Quezon Avenue and Biak na Bato to help stranded people.

The agency also sent rescue vehicles to the España area and EDSA Cubao northbound.
