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.
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:
• Tomorrow: Aurora, Bataan, Metro Manila, CALABARZON, Bicol Region, Dinagat Islands, and most of MIMAROPA and Visayas.

HAZARDS AFFECTING COASTAL WATERS
A Coastal Gale Warning is in effect for the coastal waters of Batanes, Babuyan, and the northern coast of mainland Cagayan due to strong winds associated with GORING which may cause sea travel to be risky for certain types or tonnage of vessels. Disruption in civilian maritime activities is expected over these areas (e.g., suspension of sea travel). For more information, refer to Gale Warning #1 issued at 5:00 AM today.
TRACK AND INTENSITY OUTLOOK
• GORING is forecast to move south southwestward or southward over the waters east of Northern Luzon until tomorrow evening, then turn generally south or southeastward for the rest of tomorrow through Sunday afternoon. Afterwards, the tropical cyclone will loop northward before turning to the northwest on Tuesday towards Luzon Strait. For the most of the forecast period, GORING is forecast to move slowly.
• Due to highly favorable environment, GORING is forecast to rapidly intensify and may reach typhoon category by tomorrow. It may reach its peak intensity on Sunday evening, after which it is forecast to maintain strength until the end of the forecast period. The potential for developing into a super typhoon is not ruled out.
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.
