The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday said the rains presently being experienced in Palawan are caused by a low-pressure area (LPA) within the country.

Local PAGASA chief Sonny Pajarilla said that the LPA is now in the Sulu area and has a chance to develop into a tropical depression within the next 24 to 36 hours.

“Direktang epekto na ‘yon ng LPA natin dahil ito ay nasa Sulu tapos amihan na kaya nagkaroon tayo ng interaction ng LPA at amihan — kaya maulan sa atin,” he said.

Pajarilla stated that the rains are expected until Wednesday, October 30.

He said that the rains from 9 p.m. on Sunday until 6 a.m. on Monday had accumulated 76.6 millimeters of rainfall. This is the highest volume of rains that occurred during the month which composed the 60 percent of October’s normal rate.

“Medyo may karamihan yon. Ang kagandahan nga lang, hindi naman siya ibinuhos ng anim na oras lang. Mahaba-haba ito at hindi biglaan ang taas ng tubig, may time na makababa ito sa ating drainage system at sa dagat,” he said.

Pajarilla said the effect of the rains is now observed in the southern part of the province with the same intensity in the city.

As the LPA is now at the Sulu area, it now has a low chance of developing into a tropical depression as its northeast quadrant collides with Palawan. However, once it crosses the West Philippine Sea (WPS) on Monday evening to Tuesday morning, it could develop within WPS.

“Mataas yong tiyansa na diyan habang nasa West Philippine Sea at maaring mabuo siya habang nasa area of responsibility kaya ang pinakamaapektuhan non ay Kalayaan dahil malapit lang ito habang nag-o-organize,” he said.

He said there is presently an existing gale warning, with waves expected to increase in heights of 24 meters onward until Wednesday.

On Tuesday evening, waves are expected to surge, fisherfolk are advised to avoid sea transportation over the seaboards.

“Maaaring iwasan na ng ating manlalayag ang West Philippine Sea lalo’t higit patungong Kalayaan dahil magkakaroon ng surge ang northeast winds kaya lalakas din ang alon,” he said.
