Typhoon Ulysses (Vamco) is projected to make its first landfall in Quezon province's Polillo Island between 10 pm on Wednesday, November 11, and 12 am on Thursday, November 12

Quezon and Aurora are set to feel the full force of Typhoon Ulysses (Vamco) in the coming hours, as the tropical cyclone approaches and “endangers” the two provinces, warned the state weather bureau.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in its 8 pm bulletin on Wednesday, November 11, that Ulysses is now 65 kilometers north of Daet, Camarines Norte.

The typhoon is moving west southwest toward the Quezon-Aurora area at a slightly slower pace of 15 kilometers per hour (km/h) from the previous 20 km/h.

PAGASA said Ulysses’ center neared Calaguas Islands in Camarines Norte at 6:30 pm on Wednesday, but it did not make landfall there.

The typhoon is now projected to make its first landfall in Quezon province’s Polillo Island between 10 pm on Wednesday and 12 am on Thursday, November 12, and its second landfall in the northern part of mainland Quezon between 1 am and 3 am on Thursday.

Then Ulysses will cross Central Luzon and emerge over the western seaboard of Zambales on Thursday morning.

PAGASA earlier said the typhoon may be closest to Metro Manila between 4 am and 6 am on Thursday.

As of early Wednesday evening, Ulysses continues to have maximum sustained winds of 140 km/h and gustiness of up to 195 km/h. But it may still reach its peak intensity of up to 155 km/h – referring to maximum sustained winds – before landfall.  (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

PAGASA warned that destructive winds and intense to torrential rain from Ulysses’ eyewall and inner rainbands will persist in the northern part of Camarines Norte until Wednesday evening, and then in Aurora and the northern part of Quezon from Wednesday evening to early Thursday morning.

The state weather bureau updated its rainfall outlook for Ulysses as of 8 pm on Wednesday, and also reminded the public that floods, landslides, and lahar flows are possible. Parts of Bicol were already hit by massive floods on Wednesday.

  • northern part of Eastern Samar (Maslog, Dolores, Oras, San Policarpo, Arteche, Jipapad)

In the rest of Northern Luzon, there will also be strong breeze to gale-force winds due to the surge of the northeast monsoon or hanging amihan.

PAGASA said Ulysses could slightly weaken as it crosses land “due to frictional effects in the presence of the Sierra Madre and Zambales mountain ranges.” But it is likely to remain a typhoon.

There remains a high risk of storm surges which “can cause life-threatening and damaging coastal inundation,” according to the state weather bureau.

Up to 3 meters high
  • coastal areas of Aurora, Quezon including Polillo Island, Camarines Norte, and Catanduanes
  • northern and eastern coastal areas of Camarines Sur
Up to 2 meters high
  • coastal areas of La Union, Pangasinan, Isabela, Zambales, Bataan, Pampanga, Bulacan, Metro Manila, Cavite, Batangas, northern parts of Oriental Mindoro and Occidental Mindoro including Lubang Island, Marinduque, Romblon, Masbate including Ticao and Burias Islands, Albay, and Sorsogon
  • remaining coastal areas of Camarines Sur

“Moreover, there is also a moderate risk of seiche or storm surge over the coastal areas surrounding Laguna de Bay,” PAGASA said.

Ulysses is also causing rough to very high seas, with waves 2.5 to 10 meters high, in these seaboards:

  • seaboards of areas under Signal Nos. 1, 2, and 3
  • eastern seaboard of Eastern Samar (parts that are not under a tropical cyclone wind signal)

The surge of the northeast monsoon is also triggering rough to high seas, with waves 3 to 6 meters high, in the remaining seaboards of Northern Luzon, and rough seas, with waves 2.5 to 3.5 meters high, in the seaboards of the Kalayaan Islands.

Meanwhile, waters are moderate to rough, with waves 1.5 to 2.5 meters high in these seaboards:

  • western seaboards of Palawan including Calamian Islands
  • eastern seaboards of Mindanao

Ulysses could exit the Philippine Area of Responsibility (PAR) on Friday, November 13.

Ulysses is the Philippines’ 21st tropical cyclone for 2020 – already above the yearly average of 20. (READ: LIST: PAGASA’s names for tropical cyclones in 2020)

For the next 6 months, these are PAGASA’s estimates for tropical cyclones inside PAR:

  • November 2020 – 1 to 3
  • December 2020 – 2 or 3
  • January 2021 – 0 or 1
  • February 2021 – 0 or 1
  • March 2021 – 0 or 1
  • April 2021 – 0 or 1

Since October, La Niña has been underway, which means there is more rain than usual.

Then in November, the northeast monsoon began, signaling “surges of cold temperatures.”

PAGASA warned that La Niña may enhance the northeast monsoon, which could trigger floods and landslides. – Rappler.com
