The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Friday, May 24 raised Tropical Cyclone Wind Signal No. 1 over 12 areas as tropical depression Aghon moves closer to the eastern parts of the country.

In the PAGASA’s tropical cyclone bulletin issued at 11 a.m., Signal No. 1 was hoisted over Sorsogon, Albay, Catanduanes, Camarines Sur, Eastern Samar, Samar, Northern Samar, Leyte, Southern Leyte, Dinagat Islands, Surigao del Sur, and Surigao del Norte, including Siargao and Bucas Grande Islands.

More areas in Bicol Region, Eastern Visayas, and Caraga Region may be placed under Signal No. 1 in the next bulletin at 2 p.m.

PAGASA said the highest possible wind signal that may be hoisted during the passage of Aghon is Signal No. 2.

Potential landfall or near passage expected over E. Visayas

As of 10 a.m., the center of tropical depression Aghon was located 240 kilometers east of Hinatuan, Surigao del Sur, moving west-northwestward at 10 kilometers per hour (kph).

It has maintained its maximum sustained winds of 45 kph near the center and gusts of up to 55 kph.

Based on its track forecast, PAGASA said Aghon may make a “close approach or landfall” over Eastern Visayas on Saturday morning, May 25.

PAGASA Weather Specialist Benison Estareja said Aghon may intensify into a tropical storm as it approaches or makes landfall over Northern or Eastern Samar on Saturday morning.

After that, Aghon will pass north-northwestward over Eastern Visayas before emerging over the waters off the east coast of Bicol Region on Saturday evening as a tropical storm.

On Sunday, May 26, Aghon will begin “recurving” northeastward or north-northeastward over the waters east of Luzon, while gradually intensifying.

The current forecast scenario shows an intensification into a severe tropical storm by Sunday morning and into a typhoon by Tuesday, May 28.

PAGASA said that given the westward shift in Aghon’s track forecast and the forecast probability cone, “a slightly earlier landfall over Eastern Visayas and a direct passage in the vicinity of Bicol Region are not ruled out at this time.”

Rainfall forecast

PAGASA warned that Aghon could bring moderate to heavy rains (100 to 200 millimeters) to Eastern Samar, Southern Leyte, Surigao del Norte, and Dinagat Islands until Saturday noon.

Light to moderate rains, with occasional heavy rains, (50 to 100 millimeters) are also expected in Surigao del Sur, the rest of Eastern Visayas, Albay, Sorsogon, Masbate including Ticao and Burias Islands, Catanduanes, and the eastern portion of Camarines Sur.

From Saturday noon to Sunday noon, moderate to heavy rains may continue in Northern Samar, Albay, Sorsogon, Catanduanes, Camarines Sur, and Masbate including Ticao and Burias Islands.

Meanwhile, light to moderate to, at times, heavy rains may persist in Camarines Norte, the rest of Eastern Visayas, and the southern portion of Quezon including Polillo Islands.

From Sunday noon to Monday noon, May 27, Catanduanes, Camarines Norte, and Camarines Sur may experience light to moderate rains, with occasional heavy rains.

PAGASA said Aghon may also cause moderate to rough seas along the northern and eastern seaboards of Eastern Visayas, as well as the eastern seaboard of Caraga Region.

Mariners of motor bancas and similar-sized vessels are advised to exercise caution when venturing out to sea and, if possible, avoid navigating in these conditions, particularly if inexperienced or operating ill-equipped vessels.

Estareja said Aghon may leave the country’s area of responsibility on Tuesday.
