Typhoon "Quinta" (international name: "Molave") slightly intensified on Monday afternoon while over the South China Sea and on its way outside the Philippines' area of responsibility.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has already lifted tropical cyclone warning Signal Nos. 3 and 2, but Signal No. 1 remains hoisted over Batangas, Occidental Mindoro, Lubang Island, Oriental Mindoro, Calamian Islands, and the extreme northern portion of Antique (Caluya) in its severe weather bulletin issued at 5 p.m. Monday.
"Quinta" has maximum sustained winds of 130 kilometers per hour (kph) and gustiness up to 160 kph.
Moderate to heavy with at times intense rains due to the typhoon may still prevail but fewer places may be affected, which include Occidental Mindoro, Oriental Mindoro, northern Palawan including Calamian and Cuyo Islands, Cavite, Laguna, Batangas, Rizal, Quezon, Aurora, and Isabela.
The tail-end of a frontal system may also bring moderate to heavy rains over Cagayan, Apayao, Kalinga, Abra, Ilocos Norte, and Ilocos Sur.
The combined effects of the two weather systems will likely bring light to moderate with at times heavy rains over Metro Manila, Western Visayas, Zamboanga Peninsula, Bangsamoro, and the rest of Luzon.
"Quinta" is seen to move west-northwest towards the western boundary of the Philippine area of responsibility (PAR) then exit the PAR by Tuesday morning.
As of Monday afternoon, the eye of typhoon "Quinta" was last observed at 310 kilometers west of Calapan City in Oriental Mindoro.
The State weather bureau warned of possible flooding or rain-induced landslides during heavy or prolonged rainfall especially in areas that are highly susceptible to these hazards.
Areas under Signal No. 1 may experience strong breeze to near gale conditions, as well as "rough to high seas” with waves reaching 2.5 to 7.0 meters.
Rough to very rough seas (2.5 to 5.0 m) will also prevail over the remaining seaboards of Luzon and the western coastlines of Visayas.
Sea travel remains suspended in these areas.
Meanwhile, moderate to rough seas, with waves that may reach 1.2 to 3.1 meters will prevail over the eastern seaboards of Visayas and Mindanao, and coasts of Zamboanga Peninsula.
PAGASA advised those using small boats to take necessary precautionary measures while venturing out to sea, while inexperienced mariners should avoid navigating in these conditions.
Even as "Quinta" has yet to leave the PAR, PAGASA is monitoring a new low pressure area (LPA) at 1,945 km east of Southern Luzon.
PAGASA said the LPA may enter the PAR by Wednesday or Thursday, but is less likely to develop into a tropical depression in the next 48 hours.
