HAZARDS AFFECTING LAND AREAS
Heavy Rainfall
• Today: Heavy to intense with at times torrential rains over Cagayan, Isabela, Cordillera Administrative Region, Ilocos Region, and Zambales. Moderate to heavy with at times intense rains over the northern portion of Aurora, Bataan, Tarlac, Pampanga, Bulacan, Metro Manila, Cavite, Rizal, and the rest of Cagayan Valley. Light to moderate with at times heavy rains over Camarines Norte, and the rest of Central Luzon and CALABARZON.
• Tomorrow early morning through afternoon: Heavy to intense with at times torrential rains over Ilocos Region. Moderate to heavy with at times intense rains over Benguet and Abra. Light to moderate with at times heavy rains over the rest of Cordillera Administrative Region.
• Under these conditions, scattered to widespread flooding (including flash floods) and rain-induced landslides are expected especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps, and in localities with significant antecedent rainfall.
• In the next 24 hours, the Southwest Monsoon will also bring rains over Western Visayas, MIMAROPA and the rest of Bicol Region. For more information, refer to the Weather Advisory #3 issued at 11:00 PM yesterday and the 24-Hour Public Weather Forecast issued at 4:00 AM today.
Severe Winds
• Throughout the passage of FLORITA, winds may reach storm-force in strength in any of the areas where Wind Signal No. 3 is hoisted, while winds may reach gale-force in strength in any of the areas where Wind Signal no. 2 is hoisted. Strong winds (strong breeze to near gale strength) will be experienced within any of the areas where Wind Signal no. 1 is currently in effect.
• In the next 24 hours, gusts reaching strong breeze to near gale strength may also be experienced (especially in the coastal and mountainous areas) over Metro Manila, Zambales, Bataan, Mindoro Provinces, Marinduque, Romblon, Northern Samar, Antique, Aklan, and the remaining areas of CALABARZON and Bicol Region.
HAZARDS AFFECTING COASTAL WATERS
• Under the influence of Severe Tropical Storm “FLORITA” and the prevailing Southwest Monsoon, a Gale Warning remains in effect over the seaboards of Northern and Central Luzon, most of the seaboards of Southern Luzon, and western seaboard of Visayas. For more information, refer to Gale Warning #3 issued at 5:00 AM today.
• In the next 24 hours, the Tropical Storm and the Southwest Monsoon will also bring moderate to rough seas over the remaining seaboards of Southern Luzon and Visayas (1.2 to 2.8 m). These conditions may be risky for those using small seacrafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating in these conditions.
TRACK AND INTENSITY OUTLOOK
• Severe Tropical Storm FLORITA will continue to move generally northwestward and is forecast to make landfall in the vicinity of northern Isabela (coast of Palanan, Maconacon, or Divilacan) this morning or in the vicinity of Cagayan (coast of Gattaran, Baggao, or Peñablanca) before noon or by early afternoon today. Afterwards, the storm will traverse Northern Luzon and emerge over the West Philippine Sea tonight. On the forecast track, FLORITA may exit the Philippine Area of Responsibility (PAR) tomorrow morning.
• Due to the slight shift in the track forecast, a slight intensification prior to landfall is not ruled out. However, the frictional effects of the rugged terrain of Northern Luzon will cause FLORITA to slightly weaken. Once over the West Philippine Sea, the tropical cyclone is forecast to re-intensify.
Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials. For heavy rainfall warnings, thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products issued by your local PAGASA Regional Services Division.
The next tropical cyclone bulletin will be issued at 11:00 AM today.
