MANILA — Severe tropical storm Paeng has made landfall in Camarines Sur, crossed the southern tip of Catanduanes and is expected to head toward the Calabarzon-Metro Manila area, state weather bureau PAGASA said early Saturday.

On the forecast track, PAGASA said the center of Paeng will traverse the Bicol Peninsula until Saturday noon before crossing the Calabarzon-Metro Manila-southern-Central Luzon area Saturday afternoon through early Sunday morning.

Paeng could weaken into a tropical storm within 24 hours, possibly earlier, due to "frictional effects" with interaction with the Luzon landmass, according to the weather agency.

But it may re-intensify into a severe tropical storm once it reaches the West Philippine Sea.

Paeng was last sighted in the vicinity of Siruma, Camarines Sur, packing winds of 95 kilometers per hour near the center and up to 160 kph.

It is moving west-northwestward at 30 kph.
