HAZARDS AFFECTING LAND AREAS
• Heavy Rainfall
In the next 24 hours, “JOLINA” may bring moderate to heavy rains over Eastern Samar, Dinagat Islands, and Surigao del Norte including Siargao and Bucas Grande Islands. Light to moderate with at times heavy rains over Northern Cebu, Bohol, Camiguin, and the rest of Eastern Visayas. pUnder these conditions, isolated to scattered flash flooding and rain-induced landslides are possible especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps.
• Severe Winds
Strong winds (strong breeze to near gale conditions) with occasional gusts will be experienced in areas where Tropical Cyclone Wind Signal (TCWS) #1 is in effect. Given that “JOLINA” may likely intensify into tropical storm before landfall, the highest possible TCWS that will be raised throughout its passage will be TCWS #2.
HAZARDS AFFECTING COASTAL WATERS
In the next 24 hours, Tropical Depression “JOLINA” may bring moderate to rough seas (1.2 to 2.8 m) over the eastern seaboards of Visayas and Mindanao. Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.
TRACK AND INTENSITY OUTLOOK
• On the forecast track, “JOLINA” will track generally northwestward parallel to the east coast of the country until it makes landfall over Northern Luzon by Thursday morning (09 September). Then it will move westward while traversing over Northern Luzon and may re-emerge over the West Philippine Sea by Thursday evening. “JOLINA” is forecast to exit the Philippine Area of Responsibility by Friday morning (10 September). However, the public is advised to continue monitoring for possible changes in the track forecast in the succeeding bulletins.
• “JOLINA” is forecast to intensify into a tropical storm by Wednesday (08 September) prior to its landfall over Northern Luzon. It will then weaken into a tropical depression as it moves over the rugged terrain of Northern Luzon.
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.
Unless an intermediate bulletin is released, the next tropical cyclone bulletin will be issued at 5:00 PM today.
