Brace for heavy to intense with at times torrential rains over Metro Manila, Bicol region, and some parts of Cagayan Valley and Central and Southern Luzon throughout Sunday with the anticipated landfall of typhoon “Rolly” (international name “Goni”).
Based on the available data, as well as those from PAGASA’s Virac and Daet doppler weather radars, Rolly was already near the shore of Catanduanes or about 185 kilometers east of Virac around 10 p.m.
Throughout the day, Rolly has maintained its maximum sustained winds of 215 kilometers per hour (kph) near the center and gustiness of up to 265 kph.
It has also stayed on course towards Bicol since afternoon while moving west-southwest at 25 kph.
The center of the eye of typhoon Rolly is still seen to make landfall at or near its current peak intensity over Catanduanes early Sunday morning.
Afterwards, the center of Rolly will traverse Camarines Sur and Camarines Norte and will proceed towards mainland Quezon province by afternoon.
It will further move inland over Cavite, Laguna, Batangas, and Rizal late afternoon until evening. This will be the closest approach of Rolly to Metro Manila.
By early Monday morning, Rolly may have already left the mainland Luzon landmass and have re-emerged over the West Philippine Sea.
While traversing Luzon, Rolly may weaken considerably and emerge as a severe tropical storm or minimal typhoon over the West Philippine Sea.
With the impending landfall of Rolly, tropical cyclone wind signal No. 4 was hoisted over Catanduanes, eastern portion of Camarines Sur (Buhi, Iriga City, Baao, Pili, Naga City, Bombon, Calabanga, Ocampo, Sagnay, Tigaon, Goa, Tinambac, Siruma, Lagonoy, Garchitorena, San Jose, Presentacion, Caramoan), and northern portion of Albay (Tiwi, Polangui, Malinao, Tabaco City, Malilipot, Bacacay, Rapu-Rapu).
Signal No. 3 was raised over Camarines Norte, the rest of Camarines Sur, the rest of Albay, Burias and Ticao Islands, Sorsogon, Quezon, Laguna, Rizal, eastern portion of Batangas (Tanauan City, Santo Tomas, Malvar, Balete, Mataas Na Kahoy, Lipa City, Cuenca, Talisay, San Nicolas, Santa Teresita, Alitagtag, San Pascual, Batangas City, San Jose, Ibaan, Taysan, Lobo, Padre Garcia, Rosario, San Juan), Marinduque, northern portion of Oriental Mindoro (Puerto Galera, San Teodoro, Baco, Calapan City, Naujan, Victoria, Pola, Socorro, Pinamalayan), northern portion of Romblon (Concepcion, Banton, Corcuera), and Northern Samar.
Areas under Signal No. 2 were the rest of Masbate, the rest of Romblon, the rest of Oriental Mindoro, Occidental Mindoro including Lubang Island, the rest of Batangas, Cavite, Metro Manila, Bulacan, Pampanga, Bataan, Zambales, Tarlac, Nueva Ecija, central and southern portion of Aurora (Dipaculao, Maria Aurora, Baler, San Luis, Dingalan), southern portion of Quirino (Nagtipunan), southern portion of Nueva Vizcaya (Alfonso Castaneda, Dupax Del Norte, Dupax Del Sur), Pangasinan, northern portion of Samar (Catbalogan City, Jiabong, Motiong, Paranas, Hinabangan, San Sebastian, Tarangnan, Pagsanghan, San Jorge, San Jose de Buan, Matuguinao, Gandara, Santa Margarita, Calbayog City, Santo Nino, Almagro, Tagapul-An), the northern portion of Eastern Samar (San Julian, Sulat, Taft, Can-Avid, Dolores, Maslog, Oras, San Policarpo, Arteche, Jipapad), extreme northern portion of Antique (Pandan, Libertad, Caluya), and northwestern portion of Aklan (Buruanga, Malay, Nabas, Ibajay).
While traversing Luzon, typhoon Rolly will bring heavy to intense with at times torrential rains over Bicol region, Cavite, Laguna, Batangas, Rizal, Quezon, Metro Manila, Marinduque, northern portions of Oriental Mindoro and Occidental Mindoro, Bataan, Bulacan, Aurora, and eastern portions of mainland Cagayan and Isabela.
Moderate to heavy rains with at times intense rains will also prevail over Cordillera Administrative Region, and the rest of mainland Cagayan Valley and Central Luzon.
PAGASA warned that flooding, rain-induced landslides, and sediment-laden streamflows or lahar may occur during heavy or prolonged rainfall especially in areas that are highly susceptible to these hazards.
Very destructive typhoon-force winds will be experienced in areas under Signal No. 4.
Destructive typhoon-force winds may be felt in areas under Signal No. 3, damaging gale- to storm-force winds in areas under Signal No. 2, and strong breeze to near gale conditions in areas under Signal No. 1.
Elsewhere, strong breeze to near gale conditions due to the northeasterlies will be experienced over Batanes, Babuyan Islands, Ilocos Norte, Apayao, and the coastal and mountainous areas of Cagayan and Isabela that are not under Signal No. 1.
In the next 24 hours, there is a high risk of storm surge of more than 3.0 meters (m) over the northern coastal areas of Quezon including Polillo Islands, Camarines Norte, Camarines Sur, and Catanduanes; up to 3.0 m over the coastal areas of Metro Manila, Cavite, Bulacan, Pampanga, Bataan, the southeastern coastal area of Batangas (facing Tayabas Bay), and most of the southern coastal areas of Quezon; and up to 2.0 m over the coastal areas of Marinduque, Lubang Island, and Burias Island and the remaining coastal areas of Quezon, Camarines Sur, and Batangas.
This storm surge, which may be accompanied by swells and breaking waves reaching the coast can cause life-threatening and damaging coastal inundation.
Rough to "phenomenal" seas (2.5 to 16.0 m) will be experienced over the seaboard of areas where tropical cyclone warning signal is in effect and rough to very rough seas (2.5 to 5.0 m) over the remaining seaboards of Northern Luzon and the eastern seaboards of Eastern Visayas (that are not under tropical cyclone warning signals) and Caraga.
Sea travel is risky for all types of sea vessels over these waters, especially those under storm warning signals.
Meanwhile, moderate to rough seas (1.2 to 2.5m) will be experienced over the remaining seaboards of the country.
Mariners of small sea vessels were advised to take precautionary measures when venturing out to sea, while inexperienced mariners should avoid navigating in these conditions.
The tropical depression being monitored by PAGASA with international name "Atsani" could still enter the Philippine area of responsibility (PAR) on Sunday afternoon. It will be assigned its local name "Siony" once inside the PAR.
It was estimated at 1,405 km east of Southern Luzon around 10 p.m. Saturday.
"Atsani" has maximum sustained winds of 55 kph near the center and gustiness of up to 70 kph, while moving northwest at 25 kph. It is likely to re-intensify into a tropical storm in the next 12 to 24 hours.
It remains less likely to affect any portion of the country over the next three days, but PAGASA advised the public to continue monitoring developments regarding this cyclone.
