Tropical depression Maymay weakened into a low pressure area (LPA) on Thursday morning, Oct. 13, while another tropical cyclone is expected to enter the country’s area of responsibility, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

In its 5 a.m. bulletin issued on Thursday, PAGASA said moderate to intense rains may prevail over Cagayan, Isabela, and Apayao until early Friday, Oct. 14.

Meanwhile, light to heavy rains may prevail over Batanes, Quirino, Nueva Vizcaya, Abra, Benguet, Ifugao, Kalinga, and Mountain Province.

“Under these conditions and considering significant antecedent rainfall, scattered to widespread flooding—including flash floods—and rain-induced landslides are expected especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps, and in localities with significant antecedent rainfall,” PAGASA said.

The weakening of Maymay prompted the lifting of all tropical cyclone wind signals.

Despite this, PAGASA said occasional gusts reaching strong to gale-force strength associated with the enhanced northeasterly surface wind flow may still be experienced over Batanes, Cagayan, Cordillera Administrative Region, and Ilocos Region, especially in the coastal and mountainous areas.

The LPA was already over the coastal waters of Casiguran, Aurora, as of 4 a.m., moving west-southwestward at 15 kilometers per hour (kph).

According to PAGASA, the LPA will move toward Aurora before dissipating within 12 hours.

Tropical depression to enter PAR

Meanwhile, PAGASA said the tropical depression outside the Philippine area of responsibility (PAR) is still likely to enter the region this Thursday morning or noon and move toward the extreme Northern Luzon in the next few days.

Once inside the PAR, the tropical depression will be given the local name “Neneng.”

PAGASA estimated its location 1,765 km east of Northern Luzon around 3 a.m., Thursday.

It has maintained its maximum sustained winds of 45 kph near the center and gustiness of up to 55 kph, while moving west-northwestward at 15 kph.

Shear line to bring rains over Aurora, parts of Ilocos Region

In the next 24 hours, the shear line—a region where warm and cold winds converge—will bring cloudy skies with scattered rains and thunderstorms over Ilocos Norte, Ilocos Sur, La Union, and Aurora.

PAGASA advised those in these areas to be vigilant against possible flash floods or landslides during moderate to heavy rains.

Meanwhile, the rest of the country, including Metro Manila, will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.

The public is also advised to stay vigilant against possible flash floods or landslides during severe thunderstorms, which are often accompanied by sudden heavy rains, lightning, thunder, gusty winds, and sometimes hail.

Due to the surge of northeasterly surface wind flow, PAGASA said rough to very rough seas may also prevail over the seaboards of Northern and Central Luzon and the eastern seaboard of Southern Luzon.

Meanwhile, moderate to rough seas may prevail over the western seaboards of Central and Southern Luzon.

“These conditions may be risky for those using small seacrafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions,” PAGASA advised.
