Though Jolina (Conson) is no longer a typhoon, it is still bringing torrential rain on Tuesday, September 7. Meanwhile, Tropical Storm Chanthu will be given the local name Kiko once it enters PAR.

Jolina (Conson) weakened from a typhoon into a severe tropical storm as it moved over mainland Masbate at 11 am on Tuesday, September 7, the state weather bureau announced mid-afternoon.

Jolina’s maximum sustained winds decreased from 120 kilometers per hour to 110 km/h, prompting the downgrade. Its gustiness is up to 135 km/h.

The severe tropical storm was last spotted in the vicinity of Baleno, Masbate, still moving west northwest at 15 km/h, according to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).

Though Jolina is no longer a typhoon, it is still bringing torrential rain to parts of Luzon and the Visayas on Tuesday. This means floods and landslides remain possible in areas affected by Jolina.

Storm surges 0.5 to 1 meter high could hit coastal areas in the following provinces in the next 24 hours, possibly threatening life and property:

  • Biliran
  • Sorsogon
  • Samar
  • Masbate

“In addition, coastal areas of localities under [tropical cyclone wind signals]…may experience coastal flooding due to hazardous surf conditions,” PAGASA said.

Sea trips remain suspended due to Jolina as well.

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
  • northern and eastern seaboards of Mindanao

Jolina is projected to continue moving west northwest for the rest of Tuesday. After crossing Masbate and the Ragay Gulf, it might make another landfall in the southeastern part of Quezon on Tuesday evening or early Wednesday morning, September 8.

Jolina 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

For the rest of Wednesday until Thursday morning, September 9, Jolina may cross Central Luzon. It would be around east and north of Metro Manila. At that point, it also may weaken further into a tropical storm.

Finally, Jolina could emerge over the West Philippine Sea before noon on Thursday. 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.

Meanwhile, the tropical depression outside PAR has since intensified into a tropical storm. It was given the international name Chanthu.

PAGASA said Tropical Storm Chanthu was located 1,225 kilometers east of Central Luzon as of Tuesday morning.

It is moving west northwest over the Philippine Sea at 25 km/h.

If Chanthu maintains its speed and direction, it would enter PAR on Tuesday evening or Wednesday morning. Its local name would be Kiko.

At the moment, Chanthu has maximum sustained winds of 85 km/h and gustiness of up to 105 km/h.

It could strengthen further into a severe tropical storm within 12 to 24 hours, and eventually into a typhoon by Thursday.

Fortunately, Chanthu or the potential Kiko is likely to stay far from Philippine landmass.

PAGASA, however, is not ruling out the possibility of Signal No. 1 being raised in extreme Northern Luzon. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

Jolina is the Philippines’ 10th tropical cyclone for 2021 and the first for September.

For the next six months, these are PAGASA’s estimates for the number of tropical cyclones inside PAR:

2021
  • September – 2 or 3
  • October – 2 or 3
  • November – 2 or 3
  • December – 1 or 2
2022
  • January – 0 or 1
  • February – 0 or 1

An average of 20 tropical cyclones form within or enter PAR each year. (READ: LIST: PAGASA’s names for tropical cyclones in 2021– Rappler.com
