PAGASA also warned that sea travel is risky for all vessels in the seaboards of areas under tropical cyclone wind signals.

Based on Ambo’s latest forecast track, said PAGASA, the typhoon might pass close to Northern Samar on Thursday evening before making landfall in the Albay-Sorsogon area early Friday morning.
