PAGASA sees Neneng strengthening into a tropical storm by Saturday evening, October 15, or early Sunday morning, October 16

MANILA, Philippines – Tropical Depression Neneng weakened a bit as it accelerated over the Philippine Sea on Friday morning, October 14, though it is still expected to intensify during the weekend.

Neneng’s maximum sustained winds decreased from 55 kilometers per hour to 45 km/h, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in a press conference past 11 am on Friday. Its gustiness went down to 55 km/h from the previous 70 km/h.

But PAGASA sees Neneng strengthening into a tropical storm by Saturday evening, October 15, or early Sunday morning, October 16.

As of Friday morning, the tropical depression was located 835 kilometers east of extreme Northern Luzon, moving west southwest at a faster 25 km/h from the previous 10 km/h.

It is expected to maintain its west southwest movement before turning west on Friday evening or early Saturday morning.

Neneng will then keep moving west until it makes landfall in or passes very close to Babuyan Islands or Batanes on Sunday.

PAGASA called on the public to prepare for possible floods and landslides during the weekend, as Neneng will trigger rain.

Saturday, October 15

Light to moderate rain, with at times heavy rain
  • Batanes
  • Cagayan including Babuyan Islands
  • Apayao
  • Kalinga

Sunday, October 16

Moderate to heavy rain, with at times intense rain
  • Batanes
  • Babuyan Islands
  • Cagayan
  • Apayao
  • Ilocos Norte
  • Ilocos Sur
Light to moderate rain, with at times heavy rain
  • rest of Cordillera Administrative Region
  • rest of Ilocos Region

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

Signal No. 2 is the highest possible wind signal since Neneng is projected to intensify into a tropical storm.

Meanwhile, the following gale warning has been in effect since 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 could leave the Philippine Area of Responsibility (PAR) on Monday, October 17.

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 PAR 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
