Typhoon Aghon (Ewiniar) is expected to leave the Philippine Area of Responsibility on Wednesday, May 29. It is still 'partly influencing' the southwesterly windflow.

MANILA, Philippines – Typhoon Aghon (Ewiniar) accelerated further early Wednesday, May 29, ahead of its exit from the Philippine Area of Responsibility (PAR).

In its 5 am bulletin on Wednesday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Aghon was last spotted 870 kilometers east northeast of extreme Northern Luzon, moving northeast at a fast 40 kilometers per hour (km/h).

At that pace, the typhoon is expected to leave PAR on Wednesday morning or afternoon.

Aghon maintained its strength before dawn, with maximum sustained winds of 130 km/h and gustiness of up to 160 km/h.

But PAGASA said the typhoon may start weakening by Thursday, May 30, when it would already be outside PAR.

Aghon is no longer directly affecting the country due to its distance from land. There were no more rainfall warnings as of Monday, May 27, while tropical cyclone wind signals and the gale warning for coastal waters were lifted on Tuesday, May 28.

Meanwhile, PAGASA continues to monitor the southwesterly windflow, which is “partly influenced” by Aghon.
