HAZARDS AFFECTING LAND AREAS
The Southwest Monsoon enhanced by GORING will bring occasional or monsoon rains over the western portions of Central Luzon, Southern Luzon, and Visayas over the next three days. For more information, refer to Weather Advisory #6 for Southwest Monsoon issued at 11:00 AM today and 24-Hour Public Weather Forecast and Outlook at 4:00 AM today.
The wind signals warn the public of the general wind threat over an area due to the tropical cyclone. Local winds may be slightly stronger/enhanced in coastal and upland/mountainous areas exposed to winds. Winds are less strong in areas sheltered from the prevailing wind direction.
• Moderate to significant impacts from storm-force winds are possible within any of the areas where Wind Signal No.3 is hoisted.
• Minor to moderate impacts from gale-force winds are possible within any of the areas under Wind Signal No. 2.
• Minimal to minor impacts from strong winds are also possible within any of the areas under Wind Signal No. 1.
The enhanced Southwest Monsoon will continue to bring gusty conditions over the following areas not under any Wind Signal, especially in coastal and upland/mountainous areas exposed to winds:
• Today: Bataan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Visayas, Dinagat Islands, and Camiguin.
• Tomorrow: Bataan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Visayas, Dinagat Islands, Camiguin, and most of Zamboanga Peninsula.
• Tuesday: Aurora, Bataan, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Visayas, Dinagat Islands, Camiguin, and most of Zamboanga Peninsula.
HAZARDS AFFECTING COASTAL WATERS
A Gale Warning is in effect for the northern and eastern coastal waters of Luzon. Disruption in civilian maritime activities is expected over these areas (e.g., suspension of sea travel) due to hazardous sea condition. For more information, refer to Gale Warning #5 issued at 5:00 AM today.
TRACK AND INTENSITY OUTLOOK
• GORING is forecast to begin its loop over the Philippine Sea east of Cagayan-Isabela area today. The super typhoon will then turn northeastward and northward tomorrow before shifting northwestward on Tuesday. On the track forecast, GORING will make landfall over the southern portion of Taiwan on Wednesday evening or on Thursday early morning.
• GORING is forecast to remain at super typhoon category until it makes landfall over southern Taiwan. Land interaction with Taiwan’s rugged terrain will weaken the super typhoon. It is likely that GORING will emerge over the Taiwan Strait and exit the PAR region on Friday as a severe tropical storm or a typhoon in its lowest limit.
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 5:00 PM today.
