While Tropical Depression Neneng remains far from land, its trough or extension will cause scattered rain showers and thunderstorms on Friday, October 14

MANILA, Philippines – The trough or extension of Tropical Depression Neneng will affect several areas in Southern Luzon and Eastern Visayas on Friday, October 14.

Neneng was last spotted 1,015 kilometers east of extreme Northern Luzon, moving west northwest at 10 kilometers per hour (km/h), said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in a briefing past 5 am on Friday.

The tropical depression still has maximum sustained winds of 55 km/h and gustiness of up to 70 km/h.

While Neneng remains far from land, its trough is bringing scattered rain showers and thunderstorms to the following areas:

  • Bicol
  • Quezon
  • Marinduque
  • Romblon
  • Palawan
  • Biliran
  • Eastern Samar
  • Northern Samar
  • Samar

PAGASA warned that flash floods and landslides are possible during periods of moderate to heavy rain.

Neneng itself could trigger heavy rain in Northern Luzon starting Saturday, October 15.

Signal No. 1 may also be raised for the eastern part of Northern Luzon as early as Friday morning or afternoon, to give the public 36 hours to prepare for strong winds from Neneng.

The tropical depression is expected to move west southwest for the rest of Friday before turning west on Saturday, then west northwest toward extreme Northern Luzon on Sunday, October 16.

It could make landfall in or pass very close to Babuyan Islands or Batanes on Sunday.

Neneng may also strengthen into a tropical storm by Saturday, which means Signal No. 2 would be the highest possible wind signal.

There is a chance of further intensification before Neneng’s possible landfall as well.

As for coastal waters, a new gale warning was issued at 5 am on Friday due to the northeasterly surface windflow.

  • northern and western seaboards of Northern Luzon (Batanes, northern coast of Cagayan including Babuyan Islands, Ilocos Norte, Ilocos Sur, La Union, Pangasinan) – rough to very rough seas, with waves 2.8 to 4.5 meters high
  • eastern seaboard of Northern Luzon (Isabela, eastern coast of Cagayan) – rough seas, with waves 2.8 to 4 meters high

PAGASA advised fishing boats and other small vessels not to sail, and larger vessels to watch out for big waves.

The weather bureau added that the surge of the northeasterly surface windflow and Neneng may cause moderate to rough seas in the eastern seaboards of Central Luzon and Southern Luzon. Waves could be 1.5 to 3.5 meters high, making conditions risky for small vessels.

Neneng is the Philippines’ 14th tropical cyclone for 2022 and the second for October.

PAGASA expects 5 to 9 tropical cyclones to enter or develop inside the Philippine Area of Responsibility from October 2022 to March 2023. Per month, these are the weather bureau’s estimates:

  • October 2022 – 2 to 4
  • November 2022 – 2 or 3
  • December 2022 – 1 or 2
  • January 2023 – 0 or 1
  • February 2023 – 0 or 1
  • March 2023 – 0 or 1
