LPA forms, trough to bring rains today

by Malou Talosig-Bartolome

A cloudy and most probably rainy Immaculate Conception Day. Bring your umbrellas when you go out to the church today.

State weather forecaster Pagasa said the cloud formation they spotted yesterday has already transformed into a low-pressure area 1,200 kilometers outside the Philippine Area of Responsibility (PAR).

“Sa mga susunod na araw, may tsansa na maging bagyo ito or tropical cyclone,” Pagasa weather specialist Benison Estareja said in his 4 am advisory.

If the LPA morphs into a typhoon, it will be called Rosal, the first typhoon for December.

Shear line and trough causing rains

Two weather systems are causing the rains today – the shear line and trough of LPA.

The shear line – the narrow zone near the equator where cold and warm winds converge – will continue to bring rain to northern Luzon.

Cagayan, Apayao and Ilocos Norte will experience rains, which at some point, may be heavy. 

Around noon to afternoon, it will also be rainy in Isabela, Abra, Kalinga, Ilocos Sur and Batanes.

“Inaasahan itong shear line na bababa at magpapaulan sa malaking bahagi ng eastern Luzon,” Estareja said.

The trough or the extension of the LPA will be bringing rains to the following provinces:






Eastern Visayas region

Central Visayas region


Northern Mindanao region


Davao region

This early morning, around 5:45 am, many portions of Mindanao woke up with light to moderate rains, sometimes heavy rains. These are:

Misamis Occidental

Misamis Oriental



Dinagat Islands

Meanwhile, Metro Manila and the rest of the country will experience cloudy skies with localized thunderstorms.

Pagasa warned of possible flash floods or landslides due to scattered light to moderate to, at times, heavy rains and severe thunderstorms.
