"Rapid de-escalation of wind signals remains likely as Karding moves further away from the landmass of Luzon," PAGASA said.

"High waves breaking along the coast of Zambales, Bataan, and Pangasinan may cause flooding or inundation in exposed and low-lying coastal communities."

PAGASA earlier urged residents of Metro Manila and nearby provinces to "take action", saying severe flooding was possible due to rains from the tropical cyclone.

It issued a "red" or heavy rainfall warning for Metro Manila, Tarlac, Nueva Ecija, Pampanga, Bulacan, and Rizal on Sunday at 11 p.m.

An orange warning was raised over Quezon (General Nakar, Infanta, Mauban, Real), Zambales, Bataan, Laguna, Batangas, and Cavite, with threatening floods as its associated hazard.
