  • Burias
  • Bondoc Peninsula
  • Marinduque
  • Romblon
  • Oriental Mindoro
  • Batangas

The state weather bureau warned that storm surges 0.5 to 1 meter high may threaten life and property.

“In addition, coastal areas of localities under [tropical cyclone wind signals], especially those at No. 2, may experience coastal flooding due to hazardous surf conditions,” PAGASA said.

It remains dangerous to travel by sea due to Jolina.

Rough to very rough seas (waves 2.5 to 5 meters high)

Travel risky for all vessels, inexperienced mariners should seek safe harbor

  • seaboards of areas under Signal No. 2
Moderate to rough seas (waves 1.2 to 2.8 meters high)

Small vessels must take precautionary measures, inexperienced mariners should avoid navigation

  • seaboards of areas under Signal No. 1
  • remaining seaboards of Visayas

From the Sibuyan Sea, Jolina could make landfall in or pass near the Bondoc Peninsula-Marinduque area on Wednesday morning. This would already be its seventh landfall.

Then it is projected to cross Tayabas Bay before it makes another landfall in the Quezon-Batangas area on Wednesday afternoon.

Jolina had made landfall six times as a typhoon:

Monday, September 6

  • Hernani, Eastern Samar – 10 pm

Tuesday, September 7

  • Daram, Samar – 2 am
  • Santo Niño, Samar – 3:40 am
  • Almagro, Samar – 6:30 am
  • Tagapul-an, Samar – 7:50 am
  • Dimasalang, Masbate – 10 am

After hitting the Quezon-Batangas area, Jolina may cross other parts of Calabarzon – south of Metro Manila – and Central Luzon. It might weaken into a tropical storm during this period.

Finally, Jolina could emerge over the West Philippine Sea before noon on Thursday, September 9. It may regain strength beginning Thursday afternoon as it heads for the southern China-northern Vietnam area.

It is likely to leave the Philippine Area of Responsibility (PAR) on Friday morning, September 10. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)
