MANILA - Typhoon Rolly made its third landfall in the vicinity of San Narciso, Quezon on Sunday noon ahead of its approach to Metro Manila, the state weather bureau said.
The world's strongest storm so far this year was last estimated over the coastal waters of Mulanay town in Quezon, moving west at 25 km per hour with maximum winds of 175 kph near the center and gusts of up to 240 kph.
Metro Manila and other provinces north and south of it remain under tropical cyclone warning signal no. 4, according to PAGASA.
Rolly is forecast to traverse the Batangas-Cavite area, and the center of the eye of the storm is estimated to be around 70 km south of Metro Manila between 4 p.m. to 7 p.m., said PAGASA weather forecaster Ariel Rojas.
"Mapanganib pa rin po at mapaminsala pa rin ang dala niyang hangin at ulan na posibleng magdulot ng pagbaha at pagguho ng lupa," Rojas told ABS-CBN's TeleRadyo.
(Typhoon Rolly's rains and winds remain dangerous and destructive and may possibly cause flooding and landslide.)

The country's 18th storm this year is expected to leave the Philippine area of responsibility between Monday evening and early Tuesday, Rojas said.
On Sunday, Rolly will bring heavy to intense rains over Metro Manila, Calabarzon, Marinduque, Romblon, Mindoro Provinces, Bataan, Bulacan, Aurora, and the eastern portions of mainland Cagayan and Isabela.
Moderate to heavy rains rains will prevail over the Cordilleras and the rest of mainland Cagayan Valley and Central Luzon while light to moderate with at times heavy rains will be experienced over Zamboanga peninsula, Bangsamoro, Western Visayas and the rest of Luzon.
PAGASA warned of flooding, rain-induced landslides, and sediment-laden streamflows (e.g. lahar) during heavy or prolonged rainfall especially in areas that are highly susceptible to these hazards.
PAGASA WARNS VS STORM SURGES
The weather bureau also warned there is a high risk of storm surge of up to 3 meters 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.
A storm surge of up to 2 meters could also affect the coastal areas of Marinduque, Lubang Island, Albay, Masbate (including Ticao and Burias Islands), the northern coastal area of Mindoro Provinces, and the remaining coastal areas of Quezon, and Batangas.
There may have been a Fujiwara effect - or the interaction between two weather disturbances - between Typhoon Rolly and Tropical Storm Siony, said Rojas.
Siony (International name: Atsani) had entered the PAR on Sunday morning and was last estimated 1,365 km east of Central Luzon as of 10 a.m., PAGASA earlier said.
"Posible na nagkaroon ng Fujiwara effect. Before nag-landfall itong si Rolly sa Bicol region, biglang umangat ang movements ni Siony," Rojas said.
Siony may hit extreme northern Luzon as a severe tropical storm, but its track could still change, he added.
