The center of Typhoon Rolly (Goni) will move toward the Batangas-Cavite area late Sunday afternoon until evening, November 1

Typhoon Rolly (Goni) made its 3rd landfall in San Narciso, Quezon, at 12 pm on Sunday, November 1.

It earlier made landfall as a super typhoon in Bato, Catanduanes, at 4:50 am, then in Tiwi, Albay, at 7:20 am.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in a bulletin released shortly before 3 pm that Rolly was already over the coastal waters of Mulanay, Quezon. It continues to move west at 25 kilometers per hour (km/h).

Rolly also weakened further, with its maximum sustained winds going down from 215 km/h to 175 km/h, and its gustiness decreasing from 295 km/h to 240 km/h. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

Though Rolly has been weakening, it remains a powerful typhoon. PAGASA warned that “violent winds and intense rainfall” from Rolly’s eyewall and inner rainbands are “prevailing or expected within the next 12 hours” in these areas:

  • Marinduque
  • Laguna
  • eastern part of Batangas
  • Cavite

PAGASA said Rolly’s center will continue to move over the Marinduque-central Quezon area on Sunday afternoon, then toward the Batangas-Cavite area late Sunday afternoon until evening.

Between 4 pm and 7 pm, the center of the eye of the typhoon would be located around 70 kilometers south of Metro Manila.

Rolly is forecast to exit mainland Luzon landmass and emerge over the West Philippine Sea on Sunday night, weaker though still classified as a typhoon.

PAGASA added that strong breeze to near gale conditions due to the northeasterlies will be experienced over the rest of Northern Luzon that are not under Signal No. 1.

In terms of rainfall, parts of Luzon, and a few areas in the Visayas and Mindanao, will still see varying degrees of rain for the rest of Sunday.

Heavy to intense rain
  • Calabarzon
  • Metro Manila
  • Marinduque

  • rest of Luzon
  • Western Visayas
  • Zamboanga Peninsula

There is still a high risk of storm surges in the next 24 hours. These storm surges, “which may be accompanied by swells and breaking waves reaching the coast, can cause life-threatening and damaging coastal inundation.”

Up to 3 meters high
  • northern coastal areas of Quezon including Polillo Island
  • coastal areas of Metro Manila, Cavite, Bulacan, Pampanga, Bataan
  • southeastern coastal area of Batangas, facing Tayabas Bay
  • most of the southern coastal areas of Quezon
Up to 2 meters high
  • coastal areas of Marinduque, Lubang Island, Albay, Masbate including Ticao and Burias Islands
  • northern coastal area of Occidental Mindoro and Oriental Mindoro
  • remaining coastal areas of Quezon and Batangas

“Moreover, there is also a moderate to high risk of seiche or storm surge over the coastal areas surrounding Laguna de Bay and Taal Lake,” added PAGASA.

Travel is also risky for all types of vessels in:

  • seaboards of areas under tropical cyclone wind signals – rough to phenomenal seas, with waves 2.5 to 16 meters high
  • remaining seaboards of Northern Luzon as well as eastern seaboards of Eastern Visayas that are not under a tropical cyclone wind signal and Caraga – rough to very rough seas, with waves 2.5 to 5 meters high

In the remaining seaboards of the country, there are moderate to rough seas, with waves 1.2 to 2.5 meters high. PAGASA advised those using small vessels to take precautionary measures, while “inexperienced mariners should avoid navigating in these conditions.”

Rolly could leave the Philippine Area of Responsibility (PAR) in the early hours of Tuesday, November 3.

Meanwhile, Tropical Storm Siony (Atsani) already entered PAR on Sunday, though it is not seen to have any effect on the country, at least for the next 2 to 3 days.

Rolly is the Philippines’ 18th tropical cyclone for 2020, while Siony is the 19th.

An average of 20 tropical cyclones form within or enter PAR each year.

These are PAGASA’s latest estimates for the number of tropical cyclones inside PAR in the next 6 months:

  • 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

Last October 2, the state weather bureau warned Filipinos to expect more rain in the coming months due to the onset of La Niña– Rappler.com
