Tropical depression Maymay will likely continue to move slowly or remain almost stationary toward the eastern coast of Central Luzon in the next 12 hours and may weaken into a low pressure area (LPA) as it approaches the country’s landmass, based on the latest bulletin of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

In its 5 a.m. bulletin released on Wednesday, Oct. 12, PAGASA said Maymay was last spotted 305 kilometers east of Baler, Aurora, while continuing to move slowly in a southwest direction.

It has maintained its maximum sustained winds of 45 kilometers per hour (kph) near the center and gusts of up to 55 kph.

Tropical Cyclone Wind Signal No. 1 remains hoisted over Isabela, Quirino, Nueva Vizcaya, Aurora, Nueva Ecija, and the extreme northern portion of Quezon (General Nakar, Infanta) including Polillo Islands, as these areas may continue to experience strong winds.

Likewise, moderate to heavy with occasional intense rains may prevail over Cagayan and Isabela, while light to moderate with occasional heavy rains may persist in Aurora.

“Under these conditions, 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.

Tropical depression outside PAR

PAGASA is also continuously monitoring a tropical depression outside the Philippine area of responsibility (PAR) as it may enter the region by Thursday, Oct. 13.

In its 4 a.m. bulletin, PAGASA said the weather disturbance was last seen 1,920 kilometers east of Southern Luzon.

It has maintained its maximum sustained winds of 45 kph and gustiness of 55 kph, while moving slowly northeastward.

Once inside the PAR, this tropical depression will be locally called “Neneng.”

Shear line to bring rains over Cagayan Valley, Cordillera, Northern Luzon

In the next 24 hours, the shear line—a region where warm and cold winds converge—will bring cloudy skies with scattered to widespread rains and thunderstorms over Batanes, Apayao, Kalinga, and Ilocos Norte.

Scattered rain showers and thunderstorms may also affect Abra, Benguet, Ifugao, Mountain Province, Quirino, Nueva Vizcaya, Ilocos Sur, La Union, and Pangasinan.

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

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