Tropical Depression “Marilyn” is now inside the Philippine Area of Responsibility (PAR), entering around 9:30 a.m. Thursday morning.
At 10 a.m., Marilyn was located at 1,355 kilometers east of Casiguran, Aurora, packing maximum sustained winds of 55 kilometers per hour (kph) and gustiness of 70 kph, Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
PAGASA said Marilyn is moving towards the northwest direction at 25 kph.
It said the trough of Marilyn will bring light to moderate rains and intermittent heavy rain showers (during thunderstorms) in Luzon, including Metro Manila, and Visayas, Zamboanga Peninsula, Bangsamoro, Northern Mindanao and SOCCSKSARGEN.
Residents in these areas are advised to take precautionary measures for possible landslides and flashflood.
Meanwhile, rains experienced from Wednesday night to Thursday morning in the city was caused by a combination of the trough of Marilyn and the prevailing southwest monsoon or habagat, the local office of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
PAGASA Puerto Princesa chief Sonny Pajarilla said that the observed weather scenario “is rainy with chances of sunlight appearing”.
“Meron tayong extended ng low pressure at component ng habagat kaya nagkakaroon ng convergence dito sa Palawan. Ngayon lang ‘yan hanggang bukas tapos Sabado may mga pag-ulan-ulan pa pero hindi na tulad nito ngayon,” he said.
Pajarilla explained that the low latitude of the storm is favorable to the convergence of the northeasterly and southeasterly winds in the province.
As the cyclone will move northward, the axis of the convergence will be lifted and the pile-up of clouds will disappear, he said.
Some areas in the city experienced flooding due to the rains that occurred on Wednesday night and Thursday morning.
“Ang rain rate ay nasa intense to torrential, ang reaction ng lupa, maraming process that the surface of the earth will absorb, mababa kasi maraming buhos. Ang reaction niya ay mabagal dahil marami agad ang naibuhos so ‘yon ang naging scenario natin,” he said.
Pajarilla also mentioned that the absence of good drainage systems also contributed to the occurrence of floods in some areas.
He said that the rains occurred from 12 midnight to 2 a.m. then resumed at 4-5 a.m. which were short durations.
“Ang isang bagay din kaya nagkaroon ng pagbaha dahil wala naman maayos na drainage system ang Puerto Princesa dahil kung may maayos ay diretso lang dapat ‘yon sa mga kanal,” he said.
Pajarilla said that the amounts of rains were 85 millimeters (mm) and considered as light in terms of the 24-hour rainfall from light to moderate level.
