THE LOW PRESSURE AREA WEST OF CALAYAN, CAGAYAN HAS DEVELOPED INTO TROPICAL DEPRESSION BISING.

• HAZARDS AFFECTING LAND AREAS
• Heavy Rainfall Outlook
• Refer to Weather Advisory issued No. 9 at 5:00 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.
• 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
• 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 western seaboard of Ilocos Norte, 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 westward slowly in the next 12 hours and may exit the Philippine Area of Responsibility today. Afterwards, it will turn northeastward. Re-entry to the western boundary of the PAR is possible by Sunday (06 July). 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 Saturday afternoon or evening and may further intensify as it moves over the sea south of Taiwan.
