The southwest monsoon, which is being enhanced by Typhoon Chedeng (Guchol), is affecting western parts of Luzon and the Visayas

MANILA, Philippines – Typhoon Chedeng (Guchol) began to weaken on Saturday evening, June 10, but it is enhancing the southwest monsoon or habagat, which is dumping rain in the western parts of Luzon and the Visayas.

In a bulletin issued at 11 pm on Saturday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Chedeng’s maximum sustained winds are down to 140 km/h from the previous 150 km/h.

The typhoon’s gustiness decreased to 170 km/h from 185 km/h.

PAGASA sees Chedeng getting downgraded to a severe tropical storm within 36 hours.

On Saturday evening, the typhoon was located 910 kilometers east of extreme Northern Luzon, moving north northeast at 15 km/h and remaining far from the country’s landmass.

It is expected to accelerate north northeast or northeast and leave the Philippine Area of Responsibility on Sunday evening, June 11, or early Monday morning, June 12.

While Chedeng is not bringing rain and there are no tropical cyclone wind signals in effect, it may keep causing moderate to rough seas in the seaboards of extreme Northern Luzon on Sunday.

PAGASA advised small vessels to take precautionary measures as waves could be 2 to 3 meters high.

In a separate advisory on the enhanced southwest monsoon at 11 pm on Saturday, PAGASA warned of heavy rain in the next three days. Floods and landslides are possible.
