Rolly (Goni) strengthened from a typhoon into a super typhoon at 2 am on Sunday, November 1, then made landfall in Bato, Catanduanes, at 4:50 am.
In its 5 am bulletin on Sunday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Rolly is already in the vicinity of the municipality of Bato, still moving west southwest at 25 km/h.
As it hit land, the super typhoon had maximum sustained winds of 225 km/h and gustiness of up to 280 km/h.
Even before PAGASA upgraded Rolly to super typhoon status, it was already considered the world’s strongest tropical cyclone for 2020 so far. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)
“Within the next 12 hours, catastrophic violent winds and intense to torrential rainfall associated with the region of the eyewall and inner rainbands…will be experienced over Catanduanes, Camarines Norte, Camarines Sur, Albay, the northern portion of Sorsogon, and the central and southern portions of Quezon. This a particularly dangerous situation for these areas,” PAGASA said at 5 am on Sunday.
Signal No. 5 – the highest tropical cyclone wind signal – is now raised in parts of Bicol. Metro Manila and nearby provinces have also been upgraded to Signal No. 3.

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.
The state weather bureau also provided an updated rainfall outlook for Sunday, warning areas affected by the super typhoon to be on alert for floods and landslides.
Heavy to intense rain, with at times torrential rain
- Metro Manila
- Oriental Mindoro
- Occidental Mindoro
- eastern parts of mainland Cagayan and of Isabela
- Northern Samar
- Eastern Samar
Moderate to heavy rain, with at times intense rain
- Cordillera Administrative Region
- rest of Central Luzon
- rest of mainland Cagayan Valley
Light to moderate rain, with at times heavy rain
- rest of Luzon
- rest of Visayas
- Northern Mindanao
- Zamboanga Peninsula
In addition, there is 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.”
More than 3 meters high
- coastal areas of Catanduanes and Camarines Norte
- northern coastal areas of Quezon including Polillo Island and Camarines Sur
Up to 3 meters high
- 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 Samar, Eastern Samar
- remaining coastal areas of Quezon, Camarines Sur, 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.”
After crossing the southern part of Catanduanes, PAGASA said the center of the super typhoon will cross Lagonoy Gulf and make landfall over the southern part of Camarines Sur or the northern part of Albay on Sunday morning.
Then Rolly’s center will cross Camarines Sur and Camarines Norte before heading toward Calabarzon on Sunday afternoon.
Rolly is forecast to exit the landmass of mainland Luzon and emerge over the West Philippine Sea early Monday morning, November 2. By the time it emerges over the sea, it would have weakened back into a typhoon.
Rolly could leave the Philippine Area of Responsibility (PAR) in the early hours of Tuesday, November 3.
Meanwhile, Atsani – the tropical cyclone outside PAR that PAGASA has also been monitoring – reintensified from a tropical depression into a tropical storm at 2 am on Sunday.
Tropical Storm Atsani now has maximum sustained winds of 65 km/h and gustiness of up to 80 km/h. It is likely to intensify further into a severe tropical storm in the next 24 to 36 hours.
As of early Sunday, the tropical storm is 1,280 kilometers east of Southern Luzon, moving west northwest at a relatively fast 30 km/h.
Atsani is expected to join Rolly inside PAR on Sunday afternoon. Once it enters, it will be given the local name Siony. (READ: LIST: PAGASA’s names for tropical cyclones in 2020)
But PAGASA maintained that Atsani or the potential Siony “remains less likely to affect any portion of the country over the next 2 to 3 days.”
Rolly is the Philippines’ 18th tropical cyclone for 2020, while Siony would be the 19th. Rolly is also the 5th tropical cyclone for October alone.
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
