Severe Tropical Storm Gorio slightly slowed down as it continued moving west-southwest over the Philippine Sea on Monday, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.

In its 5 PM advisory, PAGASA said the storm’s center was located 1,060 kilometers east of Extreme Northern Luzon, packing maximum sustained winds of 110 km/h and gusts of up to 135 km/h.

No tropical cyclone wind signals have been raised, but the state weather bureau warned that a change in the storm’s track could prompt the issuance of Signal No. 1 over Extreme Northern Luzon.

Gorio is forecast to move west until early Tuesday before veering west-northwest, likely exiting the Philippine Area of Responsibility by Wednesday and making landfall over Taiwan’s eastern coast in the afternoon.

Moderate seas of up to two meters are expected over the coastal waters of Extreme Northern Luzon.

PAGASA advised small boat operators to take precautionary measures and avoid sailing in these conditions.
