Tropical Depression Obet remains expected to cross extreme Northern Luzon or mainland Northern Luzon between Friday evening, October 21, and Saturday morning, October 22

MANILA, Philippines – Tropical Depression Obet slowed down on Wednesday afternoon, October 19, moving at just 10 kilometers per hour over the Philippine Sea. It was earlier moving at 15 km/h.

Obet was last spotted 920 kilometers east of extreme Northern Luzon, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in a briefing past 5 pm on Wednesday.

The tropical depression shifted west southwest, a direction it is expected to maintain until early Friday morning, October 21, before it turns west toward Northern Luzon or the Luzon Strait.

It remains expected to cross extreme Northern Luzon or the northern part of mainland Northern Luzon between Friday evening and Saturday morning, October 22.

Obet still had maximum sustained winds of 45 km/h and gustiness of up to 55 km/h on Wednesday afternoon. But it may strengthen into a tropical storm by late Friday or early Saturday.

“Further intensification is likely once Obet reaches the West Philippine Sea,” added PAGASA.

The weather bureau maintained the following rainfall forecast for Obet:

Early Friday morning, October 21, to early Saturday morning, October 22

Moderate to heavy rain, with at times intense rain
  • Babuyan Islands
  • Ilocos Norte
  • Apayao
  • northern part of mainland Cagayan
Light to moderate rain, with at times heavy rain
  • Batanes
  • northern part of Ilocos Sur
  • Abra
  • Kalinga
  • rest of mainland Cagayan

Early Saturday morning to afternoon, October 22

Light to moderate rain, with at times heavy rain
  • Batanes
  • Babuyan Islands
  • Apayao
  • northern part of Abra
  • Ilocos Norte
  • northern part of Ilocos Sur

PAGASA also warned that the shear line may continue to bring scattered rain showers and thunderstorms to these areas on Wednesday evening:

  • Ilocos Norte
  • Apayao
  • Batanes
  • Cagayan including Babuyan Islands
  • Isabela
  • Aurora

The shear line is the point where the northeasterly surface windflow and the easterlies meet.

Floods and landslides are possible in areas affected by the shear line and areas to be affected by Obet.

Meanwhile, tropical cyclone wind signals may be raised for some areas in Northern Luzon starting Wednesday evening or Thursday morning, October 20.

The highest possible wind signal is Signal No. 2 since Obet is likely to become a tropical storm.

But strong to gale-force winds are already being experienced in the northernmost parts of Luzon due to the northeasterly surface windflow, particularly in these areas:

  • Batanes
  • Babuyan Islands
  • northern part of mainland Cagayan
  • northern part of Apayao
  • northern part of Ilocos Norte

Also due to the surge of the northeasterly surface windflow, PAGASA issued a new gale warning at 5 pm on Wednesday. Rough to very rough seas are expected in these seaboards:

  • northern and eastern seaboards of Northern Luzon (Batanes, Cagayan including Babuyan Islands, northern coast of Ilocos Norte) – waves 3.4 to 6 meters high
  • western seaboard of Northern Luzon (western coast of Ilocos Norte, Ilocos Sur, La Union, Pangasinan) – waves 3.4 to 5 meters high

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

The surge of the northeasterly surface windflow and Obet may also trigger moderate to rough seas, which could be risky for small vessels, in the following seaboards:

  • seaboards of Central Luzon – waves 1.5 to 3.5 meters high
  • western and eastern seaboards of Southern Luzon – waves 1.2 to 3 meters high

Based on Obet’s latest forecast track, it could leave PAR on Saturday afternoon.

Obet is the country’s 15th tropical cyclone for 2022 and the third 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
