MANILA, Philippines – Rainfall warnings were heightened and more areas were placed under tropical cyclone wind signals due to Tropical Storm Enteng (Yagi) on Monday morning, September 2.

Enteng was located 100 kilometers north northwest of Daet, Camarines Norte, or 115 kilometers east northeast of Infanta, Quezon, as of 7 am on Monday.

The tropical storm is moving west northwest at 15 kilometers per hour, slightly faster than its speed of 10 km/h at 5 am but considerably slower than the 30 km/h at 2 am.

Enteng could make landfall in Isabela or Cagayan on Monday afternoon or evening, according to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA).

PAGASA is also not ruling out landfall in the northern part of Aurora if the tropical storm’s track shifts further westward.

Enteng had slightly intensified before dawn, with its maximum sustained winds at 75 km/h. Its gustiness is up to 90 km/h.

The rainfall forecast in PAGASA’s 8 am bulletin shows Metro Manila among the areas which are already seeing heavy to intense rain, from moderate to heavy previously.

Monday, September 2

• Torrential rain (> 200 millimeters): Camarines Norte, Camarines Sur, Albay, Quezon including Polillo Island
• Heavy to intense rain (100-200 mm): Metro Manila, Bulacan, Aurora, rest of Calabarzon, Catanduanes, Sorsogon
• Moderate to heavy rain (50-100 mm): Isabela, Quirino, Nueva Ecija, Marinduque, Romblon, Masbate

Tuesday, September 3

PAGASA reiterated that there could be more rain from Enteng in mainland Luzon if the tropical storm’s track shifts further west due to the “developing ridge of high pressure” located above it.

Areas affected by Enteng must continue to watch out for floods and landslides.

Meanwhile, Metro Manila was also among those added to the list of areas under tropical cyclone wind signals as of 8 am on Monday. Below is the complete list.

Floods and landslides are likely, too.

In addition, the enhanced southwest monsoon will cause strong to gale-force gusts in these areas:

Monday, September 2

• Ilocos Region, Zambales, Bataan, Pampanga, Aurora, Bulacan, Metro Manila, Calabarzon, Mimaropa, Bicol, Visayas

Tuesday, September 3

Wednesday, September 4

• Zambales, Bataan, Aurora, Bulacan, Metro Manila, Calabarzon, Mimaropa, Bicol, Western Visayas

Enteng and the enhanced southwest monsoon are affecting coastal waters as well.

PAGASA released a new gale warning at 5 am on Monday, covering the eastern seaboards of Northern Luzon and Central Luzon (waves 3.7 to 5 meters high) as well as the eastern and southern seaboards of Southern Luzon (waves 3.7 to 4.5 meters high). Seas are rough to very rough, so travel is risky for small vessels.

Moderate to rough seas are also seen in the northern seaboard of Northern Luzon and the western seaboard of Central Luzon (waves 1.5 to 3.5 meters high), as well as the western seaboard of Southern Luzon, the remaining southern seaboard of Southern Luzon not covered by the gale warning, and the seaboards of Western Visayas (waves 1.5 to 3 meters high). The weather bureau advised small vessels not to venture out to sea.

In the rest of the country, slight to moderate seas are expected (waves 1 to 2.5 meters high). Small vessels must take precautionary measures or avoid sailing, if possible.

PAGASA expects Enteng to generally turn west northwest beginning early Tuesday morning, September 3. The weather bureau is not ruling out another landfall in Babuyan Islands.

Enteng may also slow down from Tuesday to Wednesday, September 4, while it gradually intensifies over the Luzon Strait.

Enteng may strengthen into a severe tropical storm by Wednesday and into a typhoon by Thursday, September 5, or Friday, September 6. The weather bureau said conditions over the Philippine Sea are “favorable” for tropical cyclone intensification.

By Wednesday evening or early Thursday morning, Enteng may already be out of the Philippine Area of Responsibility.

Enteng is the country’s fifth tropical cyclone for 2024 and the first for September. PAGASA previously estimated there may be two or three tropical cyclones during the month.

There is also a 66% chance of La Niña forming in the September-November period. – Rappler.com
