MANILA, Philippines – Tropical Depression Aghon could make landfall more than once while gradually intensifying, based on the weather bureau’s forecast issued at 5 pm on Friday, May 24.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Aghon might make landfall in the southern part of Eastern Samar or Dinagat Islands by Saturday morning, May 25, as a tropical storm.

Then it could pass north northwest through the coast of Northern Samar, followed by another possible landfall in the southeastern part of Bicol – Sorsogon, Albay, or Catanduanes – by Saturday evening, still as a tropical storm.

As of 4 pm on Friday, Aghon was located 135 kilometers northeast of Hinatuan, Surigao del Sur, or 185 kilometers east southeast of Surigao City, Surigao del Norte.

The tropical depression is still moving west northwest, speeding up further from 25 kilometers per hour to 30 km/h.

It continues to have maximum sustained winds of 55 km/h and gustiness of up to 70 km/h.

The forecast as of late Friday afternoon shows it may strengthen into a tropical storm within 12 hours; a severe tropical storm on Sunday, May 26; and a typhoon on Monday, May 27.
