At least 19 areas, including Metro Manila, were placed under storm warning Signal No. 1 on Saturday evening, with Bicol and Southern Luzon still expected to take a direct hit from tropical depression “Quinta” in the next few hours.
In its severe weather bulletin issued at 11 p.m., Saturday, Oct. 24, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) raised tropical warning Signal No. 1 over Catanduanes, Sorsogon, Albay, northern part of Masbate (Mobo, Uson, Milagros, Masbate City, Baleno, Mandaon, Balud, Aroroy, Dimasalang), Burias and Ticao Islands, Camarines Norte, Camarines Sur, Quezon, Laguna, Rizal, Batangas, Cavite, Metro Manila, Occidental Mindoro, Oriental Mindoro, Marinduque, Romblon, and Northern Samar.
These areas may experience 30 to 60 kilometers per hour (kph) of winds or intermittent rains within 36 hours from the time the tropical cyclone warning has been raised.
PAGASA last observed tropical depression “Quinta” at 505 kilometers (km) east of Juban, Sorsogon or 475 km east of Virac, Catanduanes around 10 p.m.
It is currently moving at 20 kilometers per hour (kph).
Tropical depression “Quinta” is seen to continue moving west until its landfall over Bicol region between Sunday evening and early Monday, then traverse Southern Luzon until Monday evening, PAGASA said.
Thereafter, it will begin turning west-northwest until it exits the Philippine area of responsibility on Tuesday morning or afternoon, it added.
As “Quinta” is still over the sea, it could steadily intensify into a tropical storm (with maximum wind speed up to 62-88 kph) within 12 to 24 hours and may become a severe tropical storm (with maximum wind speed of 89-117 kph) prior to landfall, the weather bureau said.
So far, “Quinta” has maximum sustained winds of 55 kph and gustiness of up to 70 kph.
After it crosses the archipelago, the weather disturbance may continue to intensify while over the West Philippine Sea, reaching typhoon strength, with maximum wind speed of 118 to 220 kph, by Tuesday evening.
PAGASA said “Quinta” may begin to bring moderate to heavy rains on Sunday over Albay, Camarines Norte, Camarines Sur, Catanduanes, Sorsogon, Masbate, Northern Samar, and Quezon.
Light to moderate with at times heavy rains may also affect Aurora, Metro Manila, Cavite, Laguna, Batangas, Rizal, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Zamboanga Sibugay, Zamboanga del Norte, Zamboanga del Sur, Lanao del Sur, Maguindanao, Basilan, Sulu, Tawi-Tawi, Bukidnon, Camiguin, Misamis Occidental, Misamis Oriental, Lanao del Norte, Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur, and Visayas.
The tail-end of a frontal system will also bring moderate to heavy rains over the northern portions of mainland Cagayan including Babuyan Islands, Apayao, and Ilocos Norte and light to moderate with at times heavy rains over Batanes, and the rest of Cagayan, Apayao, and Ilocos Norte.
PAGASA warned of possible flooding, rain-induced landslides, or sediment-laden streamflow (lahar) during heavy or prolonged rainfall especially in areas that are highly susceptible to these hazards.
A gale warning is in effect on Saturday over the seaboards of Northern Luzon, and the western seaboards of Central Luzon, Batangas, Occidental Mindoro, and northern Palawan including Calamian and Kalayaan Islands due to rough to very rough seas that may reach wave heights up to 2.8 to 6.0 meters.
In the next 24 hours, rough to very rough seas will prevail over the entire seaboards of Northern and Central Luzon with wave heights reaching 3.0-5.5 meters and 2.5-3.5 meters, respectively.
The western seaboards of Bataan, Batangas, Occidental Mindoro, Lubang Island, northern Palawan, and Calamian and Kalayaan Islands may also experience waves from 2.5 to 3.0 meters high, and the seaboard of Aurora with wave heights 2.5 to 4.5 meters, and all areas under Signal No. 1 with waves reaching 2.5 to 5.5 meters.
Sea travel is suspended in these areas.
Moderate to rough seas, with waves that may reach 1.2 to 2.8 meters will prevail over the other coastlines of the country.
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.
Tropical depression “Quinta” will likely be at 35 km northwest of Virac, Catanduanes on Sunday evening; 235 km west of Calapan City in Oriental Mindoro by Monday evening; and at 745 km west of Cavite City or outside the Philippine area of responsibility by Tuesday evening.
