Rolly made its fourth landfall at 5:30 p.m. over Lobo town in Batangas.
The typhoon first made landfall in Bato, Catanduanes early Sunday, before making its second landfall in Tiwi, Albay at 7:20 a.m.
Rolly made its third landfall in the vicinity of San Narciso, Quezon on Sunday noon.
The country's 18th storm this year is expected to leave the Philippine area of responsibility by Tuesday morning.
On Sunday, Rolly will bring heavy to intense rains over Aurora and the eastern portions of mainland Cagayan and Isabela.
Light to moderate rains with at time heavy rains will prevail over Metro Manila, Calabarzon, Cordillera Administrative Region, Ilocos Region, Mimaropa, Western Visayas, Zamboanga Peninsula, Bangsamoro, Northern Mindanao, and the rest of mainland Cagayan Valley and Central 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 moderate to high risk of storm surge of up to 2 meters over the coastal areas of Cavite, Bataan, Lubang Island, the southwestern coastal area of Batangas, and the northern coastal area of Occidental Mindoro.
These storm surges, which may be accompanied by swells and breaking waves reaching the coast can cause life-threatening and damaging coastal inundation, PAGASA added.
Meanwhile, weather disturbance 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.
