• HAZARDS AFFECTING LAND AREAS
• Heavy Rainfall Outlook
• Refer to Weather Advisory issued No. 10 at 11:00 AM today for the heavy rainfall outlook due to Tropical Depression BISING and the Southwest Monsoon.
• Severe Winds
• 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.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
• Furthermore, the southwest monsoon and the periphery of BISING will also bring strong to gale-force gusts over the following areas (especially in coastal and upland areas exposed to winds):
• Today (4 July): the rest of Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Isabela, the northern portion of Aurora, Zambales, Occidental Mindoro, Marinduque, Romblon, Palawan, and Antique.
• Tomorrow (5 July): the rest of Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Isabela, the northern portion of Aurora, Zambales, Bataan, Cavite, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, and Antique.
• Sunday (6 July): the rest of Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Isabela, the northern portion of Aurora, Zambales, Bataan, Metro Manila, Cavite, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, and Antique
• HAZARDS AFFECTING COASTAL WATERS
• 24-Hour Sea Condition Outlook
• Up to rough seas over the following coastal waters:
• Up to 3.0 m: The western seaboards of Babuyan Islands and Ilocos Norte.
• Mariners of small seacrafts, including all types of motorbancas, are advised not to venture out to sea under these conditions, especially if inexperienced or operating ill-equipped vessels.
• Up to moderate seas over the following coastal waters:
• Up to 2.5 m: The northwestern seaboard of Ilocos Sur.
• Up to 2.0 m: The seaboard of Batanes, the western seaboards of La Union and Pangasinan, the remaining seaboard of Ilocos Sur.
• Mariners of motorbancas and similarly-sized vessels are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigation under these conditions.
• TRACK AND INTENSITY OUTLOOK
• Tropical Depression BISING will continue moving generally northwestward slowly in the next 12 hours and may exit the Philippine Area of Responsibility this afternoon. Afterwards, it will turn northeastward over the sea west of Extreme Northern Luzon. Re-entry to the western boundary of the PAR is possible by Sunday (06 July) morning and it may exit again the northern boundary of PAR by Monday. The forecast track is highly uncertain and a possible southward shift resulting to hoisting of Wind Signal No. 2 over Batanes and Babuyan Islands is not ruled out.
• BISING is forecast to intensify into a tropical storm by tomorrow and may further intensify as it moves over the sea south of Taiwan.
