The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in its 5 pm bulletin that Gorio was already 800 kilometers northeast of extreme Northern Luzon.

The tropical depression slowed down a bit, moving northeast toward the southern part of Japan at 15 kilometers per hour from the previous 20 km/h.

Gorio also slightly intensified, with maximum sustained winds of 55 km/h and gustiness of up to 70 km/h. It earlier had maximum sustained winds of 45 km/h and gustiness of up to 55 km/h.

PAGASA expects Gorio to strengthen into a tropical storm within 12 hours.

Gorio did not bring rain to the Philippines and tropical cyclone wind signals were not raised.

Gorio was the Philippines’ seventh tropical cyclone for 2021 and the first for August.

PAGASA is also monitoring a tropical storm outside PAR, with the international name Lupit.

Tropical Storm Lupit was 655 kilometers west of extreme Northern Luzon on Wednesday afternoon, moving northeast at 10 km/h.
