Typhoon Odette (Rai) slightly intensifies late Wednesday evening, December 15. Its maximum sustained winds are at 140 km/h.

MANILA, Philippines – Signal No. 3 was raised for some areas in the Caraga region in Mindanao late Wednesday evening, December 15, due to the approaching Typhoon Odette (Rai), which strengthened again.

Odette was last spotted 470 kilometers east of Surigao City, Surigao del Norte, moving west at a slower pace of only 15 kilometers per hour (km/h), said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in a bulletin released past 11 pm on Wednesday.

If Odette maintains its speed and direction, it would make landfall either in the Surigao provinces-Dinagat Islands area or the southern part of Eastern Visayas on Thursday afternoon, December 16.

The typhoon slightly intensified late Wednesday evening, with maximum sustained winds increasing from 130 km/h to 140 km/h. Its gustiness is now up to 170 km/h from the previous 160 km/h.

PAGASA still expects Odette to reach a peak intensity of 155 km/h before landfall.

With Odette inching closer to land, PAGASA warned parts of Mindanao and the Visayas that rain could already become torrential in the coming hours. Here is the weather bureau’s rainfall forecast as of 11 pm:

Wednesday evening, December 15, until Thursday evening, December 16

  • Heavy to intense rain, with at times torrential rain – Caraga, Misamis Oriental, Camiguin, Southern Leyte, Bohol
  • Moderate to heavy rain, with at times intense rain – Leyte, southern part of Eastern Samar, Cebu, Siquijor, Negros Oriental, Zamboanga del Norte, Lanao del Sur, rest of Northern Mindanao
  • Light to moderate rain, with at times heavy rain – Bicol, Davao Oriental, Davao de Oro, Davao del Norte, rest of Visayas, rest of Zamboanga Peninsula, rest of mainland Bangsamoro Autonomous Region in Muslim Mindanao

Thursday evening, December 16, until Friday evening, December 17

  • Heavy to intense rain, with at times torrential rain – Central Visayas, Western Visayas, Palawan including Calamian, Cuyo, and Cagayancillo Islands
  • Moderate to heavy rain, with at times intense rain – Bicol, Zamboanga Peninsula, Occidental Mindoro, Oriental Mindoro, Romblon, Lanao del Norte, Lanao del Sur, rest of Visayas
  • Light to moderate rain, with at times heavy rain – Caraga, Quezon, southern part of Aurora, rest of Northern Mindanao, rest of Mimaropa

Friday evening, December 17, until Saturday evening, December 18

  • Heavy to intense rain, with at times torrential rain – central part of Palawan including Kalayaan Islands
  • Moderate to heavy rain – Aurora, Quezon, rest of Palawan

Areas affected by Odette must watch out for floods and landslides.

PAGASA also warned that there is a “moderate to high risk” of storm surges up to 3 meters high which might cause floods “in the low-lying coastal localities of Surigao del Norte, Dinagat Islands, Agusan del Norte, Eastern Samar, Southern Leyte, Negros Occidental, Guimaras, and some localities in Camiguin, Central Visayas, Panay Island, and the northern portion of Palawan.”

PROJECTED PATH. Forecast track of Typhoon Odette (Rai) as of December 15, 2021, 11 pm.

On Thursday, moderate to very high seas are expected in seaboards of areas under tropical cyclone wind signals. Waves are estimated to be 1.2 to 10 meters high, making travel risky for all types of vessels.

Coastal waters not under any tropical cyclone wind signal in the seaboards of Northern Luzon, eastern seaboard of Central Luzon, and eastern seaboards of Southern Luzon and Mindanao are also under a gale warning due to the typhoon and the northeast monsoon or hanging amihan. Seas are rough to very rough, with waves 2.8 to 4.5 meters high.

The remaining seaboards of the Philippines not under any wind signal will have moderate to rough seas. Waves are 1.2 to 3.1 meters high and conditions are risky for small vessels.

After its projected initial landfall on Thursday afternoon, Odette is seen to cross several provinces in Central Visayas and Western Visayas before emerging over the Sulu Sea on Friday morning, December 17.

Then it could pass near or in the vicinity of Cuyo or Cagayancillo and cross the northern or central part of Palawan on Friday afternoon or evening before finally exiting landmass toward the West Philippine Sea.

PAGASA said Odette may slightly weaken as it crosses northeastern Mindanao, the Visayas, and Palawan, but it will remain a typhoon. It is also likely to reintensify over the West Philippine Sea.

The typhoon could start to weaken again on Sunday, December 19, however, as it “becomes exposed to increasing vertical wind shear and the surge of the northeast monsoon,” the weather bureau said. By this time, it would already be outside the Philippine Area of Responsibility (PAR).

The latest forecast track shows Odette leaving PAR on Saturday, December 18.

Odette is the Philippines’ 15th tropical cyclone for 2021. Around 20 form within or enter PAR each year.

Here are PAGASA’s estimates for tropical cyclones in the coming months:

  • December 2021 – 1 or 2
  • January 2022 – 0 or 1
  • February 2022 – 0 or 1
  • March 2022 – 0 or 1
  • April 2022 – 0 or 1
  • May 2022 – 1 or 2
