HAZARDS AFFECTING LAND AREAS

Heavy Rainfall
• In the next 24 hours, “JOLINA” may bring heavy to intense with at times torrential rains Eastern Visayas, Sorsogon, and Masbate. Moderate to heavy with at times intense rains are also likely over the southern portion of Quezon, Romblon, Marinduque and the rest of Bicol Region and Visayas.
• Under these conditions, scattered to widespread flooding (including flash floods) 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
• Destructive typhoon-force winds are likely to occur within any of the areas where Tropical Cyclone Wind Signal #3 is in effect. This may bring generally moderate to heavy damage to structures and vegetation.
• Damaging gale-force to storm-force winds are likely to occur within any of the areas where TCWS #2 is in effect. This may bring generally light to moderate damage to structures and vegetation.
• 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. This may result to up to very light damage to structures and vegetation.

Coastal Inundation
In the next 24 hours, the threat of coastal inundation due to storm surge of up to 0.5-1.0 m continues for the coastal localities of Eastern Samar, Samar, and Masbate which may pose threat to life and property. In addition, coastal areas of localities under TCWS, especially those at #2 and #3 may experience coastal flooding due to hazardous surf conditions.

HAZARDS AFFECTING COASTAL WATERS
• In the next 24 hours, Typhoon “JOLINA” will bring rough to very rough seas (2.5 to 5.0 m) over the seaboards of areas where TCWS #2 and #3 are in effect. Sea travel is risky for all types of seacrafts over these waters. Mariners without the proper experience should immediately seek safe harbor.
• Moderate to rough seas (1.2 to 2.8 m) will be experienced over the seaboards of areas where TCWS #1 is in effect, the remaining seaboards of Visayas, and the northern eastern seaboards of 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
• Recent landfalls: Daram, Samar (2:00 AM); Sto Niño, Samar (3:40 AM)
• Within the next 12 hours, the typhoon is forecast to move over the Samar Sea and pass over or close to the island municipalities of Samar and the northern coast of Biliran before making landfall in the vicinity of Masbate (mainland or Ticao Island). During this period, “JOLINA” may weaken into a severe tropical storm.
• Beyond the next 12 hours, “JOLINA” will move northwestward towards Burias Island and the vicinity of Ragay Gulf before making another landfall in the vicinity of southeastern Quezon tonight or tomorrow early morning. Further weakening is likely during this period.
• By tomorrow afternoon, “JOLINA” will briefly emerge over Lamon Bay before making landfall in the vicinity of northern Quezon. Throughout the remainder of tomorrow and into tomorrow morning, the tropical cyclone is forecast to cross Central Luzon (roughly to the east and north of Metro Manila). Frictional effects during its traverse of Luzon landmass will weaken “JOLINA” down to tropical storm category.
• “JOLINA” is forecast to emerge over the West Philippine Sea before noon on Thursday. Re-intensification is forecast to occur beginning on Thursday afternoon as the tropical cyclone moves west northwestward over the West Philippine Sea towards the southern China-northern Vietnam area.

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 8:00 AM today.
