MANILA, Philippines – Aghon (Ewiniar) intensified from a tropical storm into a severe tropical storm at 3 pm on Sunday, May 26, prompting the weather bureau to raise Signal No. 3 for the eastern portion of Quezon.

In a bulletin issued at 5 pm on Sunday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Aghon now has maximum sustained winds of 95 kilometers per hour from the previous 75 km/h.

Its gustiness is now up to 130 km/h from 125 km/h.

The severe tropical storm was last spotted over the coastal waters of Mauban, Quezon, at 4 pm on Sunday.

It continues to slowly move northeast, heading for Quezon’s Polillo Islands.

PAGASA said Aghon might strengthen further into a typhoon while over the sea east of Quezon, or possibly later than that – by Monday afternoon, May 27.

These are the areas under tropical cyclone wind signals as of 5 pm on Sunday:

As Aghon has maintained its slow pace, PAGASA advised the same areas to remain on alert for floods and landslides caused by moderate to torrential rain from the severe tropical storm. Rain will persist in the areas below.

Sunday afternoon, May 26, to Monday afternoon, May 27

• Greater than 200 mm: Quezon
• 100-200 mm: Aurora, eastern part of Bulacan, Rizal, Laguna, Metro Manila, Camarines Norte
• 50-100 mm: eastern part of Isabela, Nueva Ecija, rest of Bulacan, eastern part of Pampanga, Cavite, Batangas, Oriental Mindoro, Occidental Mindoro, Romblon, Burias Island, western part of Camarines Sur, Cuyo Islands, Aklan, Antique

Monday afternoon, May 27, to Tuesday afternoon, May 28

• 50-100 mm: eastern part of Isabela, northern part of Aurora, Polillo Islands

The weather bureau also said there is still a “minimal to moderate risk” of storm surges over the “exposed and low-lying coastal areas” of Cagayan, Isabela, Central Luzon, Metro Manila, Calabarzon, Occidental Mindoro, Oriental Mindoro, Marinduque, Romblon, Camarines Norte, Camarines Sur, and Burias Island within 24 hours.

The coastal waters of Aurora, Quezon, and Marinduque, as well as the southern coastal waters of Batangas and the northern coastal waters of Camarines Norte, remain under a gale warning, too. PAGASA said travel is risky for small vessels, “including all motorbancas of any type of tonnage.”

Outside those areas under the gale warning, Aghon will still cause moderate to rough seas in the northern and eastern seaboards of Luzon and the seaboard of Bicol. Waves are 1.5 to 3.5 meters high, so small boats must take precautionary measures, or if possible, avoid sailing altogether.
