MANILA--Tropical depression Ambo slowed down further while moving over the Luzon strait, the state weather bureau said Saturday, after leaving a trail of destruction in the Philippines.
In its 11 p.m. bulletin, the PAGASA said Ambo was last spotted at about 95 kilometers west of Calayan town, Cagayan, packing maximum sustained winds of 55 kilometers per hour near the center and 70 kph gusts.
It was last seen moving northeast at 10 kph. It is expected to leave the Philippine area of responsibility by Monday, according to PAGASA.
Due to Ambo's weakened state, tropical cyclone wind signals (TCWS) in some areas were lifted by the weather bureau.
TCWS No. 1 is still up in the extreme northern portion of Ilocos Norte (Burgos, Bangui, Pagudpud), the extreme northwestern portion of mainland Cagayan (Santa Praxedes, Claveria), Babuyan Islands and Batanes.
Winds of 30 to 60 kph may be expected in at least 36 hours or intermittent rains may be expected within 36 hours in these areas, the PAGASA said.
For the next 24 hours, the weather agency said light to moderate with at times heavy rains could occur over Ilocos Norte, the northern portion of Apayao, the northwestern portion of mainland Cagayan, Babuyan Islands, Batanes, the eastern portion of Isabela, and the northern portion of Aurora.
Residents in these areas were advised to take appropriate measures, coordinate with local disaster risk reduction and management offices, and continue monitoring for updates.
The PAGASA said flooding and rain-induced landslides may occur in highly to very highly susceptible areas during heavy or prolonged rainfall.
Sea travel is also risky especially for small seacrafts over the seaboards of areas under TCWS.
Ambo, the country's first typhoon this year, first made landfall on Thursday over San Policarpo in Eastern Samar and later hit Dalupiri Island, Northern Samar; Capul Island, Northern Samar; Ticao Island, Masbate; Burias Island, Masbate; and San Andres in Quezon.
The erstwhile typhoon blitzed through the affected areas, cutting off electricity and communications and forcing residents to flee to evacuation centers, amid the COVID-19 pandemic.
