ISSUED AT 11:00 AM, 25 October 2020
(Valid for broadcast until the next bulletin to be issued at 2 PM today)
"#QuintaPH" INTENSIFIES INTO A SEVERE TROPICAL STORM AS IT THREATENS THE CATANDUANES-ALBAY-SORSOGON AREA.
Track and intensity outlook:
• Track: "QUINTA" is forecast to continue moving generally westward until its landfall over the Catanduanes-Albay-Sorsogon area between this afternoon and evening. Afterwards, it will traverse the Southern Luzon area until tomorrow afternoon, then turn west-northwestward over the West Philippine Sea. It is likely to exit the Philippine Area of Responsibility (PAR) on Tuesday afternoon.
• Intensity: "QUINTA" intensified into a severe tropical storm at 8:00 AM today. Further intensification prior to landfall over Bicol Region remains likely. After crossing the Philippine archipelago, this tropical cyclone will continue intensifying over the West Philippine Sea, reaching typhoon category by Tuesday.
Hazards affecting land areas:
• Rainfall: Today through tomorrow morning, “QUINTA” will bring moderate to heavy with at times intense rains over Bicol Region, CALABARZON, Aurora, Occidental Mindoro, Oriental Mindoro, Romblon, Marinduque, Calamian Islands, Northern Samar, Eastern Samar, Samar, Biliran, Aklan, and Antique. The tail-end of a frontal system will likewise bring moderate to heavy with at times intense rains over Cagayan, Isabela, Apayao, and Ilocos Norte. These two weather systems will also bring light to moderate with at times heavy rains over Metro Manila, Cordillera Administrative Region, Zamboanga Peninsula, Bangsamoro, Northern Mindanao, Caraga, and the rest of Visayas, Cagayan Valley, Central Luzon, and MIMAROPA. Flooding (including flash floods), rain-induced landslides, and sediment-laden streamflows (i.e. lahars) may occur during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards. PAGASA Regional Services Divisions may issue local thunderstorm/rainfall advisories and heavy rainfall warnings as appropriate.
• Strong winds: Gale conditions will be experienced in areas under Tropical Cyclone Wind Signal (TCWS) #2 while strong breeze to near gale conditions will be experienced in areas under TCWS #1. Potential impacts of these wind conditions to structures and vegetation are detailed in the TCWS section of this bulletin. In other areas, strong breeze to gale conditions will also prevail over Batanes, Babuyan Islands, and the northern coastal areas of Ilocos Norte and mainland Cagayan due to the northeasterly surge.
Hazards affecting coastal waters:
• Storm surge of 1.0 to 2.0 meters may affect the coastal areas of Northern Samar, Bicol Region, and the central and southern portions of Quezon.
• Today, rough to very rough seas will prevail over the entire seaboards of Northern Luzon (3.0 to 5.5 m) and the seaboards of Aurora, Zambales, northern Palawan including Calamian and Kalayaan Islands (2.5 to 4.5 m), and all areas under TCWS #2 and #1 (2.5 to 5.5 m). Sea travel is risky over these waters, especially for small seacrafts.
• Moderate to rough seas (1.2 to 2.8 m) will be experienced over the other seaboards of the country today. Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.
