MANILA, Philippines – Typhoon Tisoy (Kammuri) slightly weakened as it continued to cross landmass before dawn on Tuesday, December 3, but it is still expected to dump more rain in parts of Luzon and the Visayas.

In a bulletin issued past 5 am on Tuesday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Tisoy is already in the vicinity of the municipality of San Pascual in Burias Island, which is in the province of Masbate.

It is again moving at a slightly faster 20 kilometers per hour (km/h) from its speed of 15 km/h when it hit land.

Tisoy had made landfall in Gubat, Sorsogon, at 11 pm on Monday, December 2. Tropical cyclones commonly weaken while crossing land, though in Tisoy’s case, it remains strong nevertheless since it is still a typhoon.

Tisoy now has maximum winds of 155 km/h from 175 km/h at the time of its landfall, and gustiness of up to 235 km/h from 240 km/h. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

PAGASA said Tisoy’s eyewall is currently bringing violent winds and intense rainfall to Camarines Norte, Camarines Sur, Albay, and Masbate. It will also affect the southern part of Quezon, Romblon, and Marinduque in the next 3 hours.

Tisoy’s eyewall first hit Northern Samar on Monday afternoon.
