(1st UPDATE) Southern Leyte, the eastern part of Bohol, Dinagat Islands, and Surigao del Norte are under Signal No. 4 as the maximum sustained winds of Typhoon Odette (Rai) reach 185 km/h

MANILA, Philippines – Parts of Mindanao and the Visayas were placed under Signal No. 4 late Thursday morning, December 16, as Typhoon Odette (Rai) intensified further ahead of its expected landfall in the Caraga region.

Odette now has maximum sustained winds of 185 kilometers per hour from the previous 165 km/h, while its gustiness increased to 230 km/h from the previous 205 km/h, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in a bulletin released past 11 am.

The typhoon’s intensification will continue until it makes landfall on Thursday afternoon, and it could reach a peak intensity of 195 km/h.

PAGASA warned that Odette is endangering the Bucas Grande-Siargao Islands area and Dinagat Islands – the possible areas where the typhoon could make its initial landfall between 1 pm and 3 pm on Thursday.

As of late Thursday morning, Odette was already 175 kilometers east of Surigao City, Surigao del Norte, still moving west northwest at 25 km/h.

  • Moderate to heavy rain, with at times intense rain – Bicol, Zamboanga Peninsula, Quezon, Occidental Mindoro, Oriental Mindoro, Romblon, Marinduque, Lanao del Norte, Lanao del Sur, rest of Visayas

PAGASA also reiterated that there is a “moderate to high risk” of storm surges up to 3 meters high “which may cause life-threatening flooding in the low-lying coastal areas of Central Visayas, Northern Mindanao, Iloilo, Guimaras, Negros Occidental, Eastern Samar, Southern Leyte, Dinagat Islands, Surigao del Norte, Surigao del Sur, Agusan del Norte, and several localities in the northern portion of Palawan including Calamian, Cuyo, and Cagayancillo Islands, Antique, the southern portion of Samar, Leyte, and Davao Oriental.”

PROJECTED PATH. Forecast track of Typhoon Odette (Rai) as of December 16, 2021, 11 am.

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 and in the eastern seaboards of Central Luzon and Southern Luzon also remain 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 first landfall on Thursday, 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 Saturday evening, December 18, or 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 that time, it would already be outside the Philippine Area of Responsibility. Odette could exit PAR by Saturday afternoon.

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
