Tropical Depression Ada further weakened as it increased in speed while maintaining its track over the Philippine Sea, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration’s (PAGASA) 11:00 a.m. bulletin.
Ada (international name: Nokaen) was last located 445 km east of Casiguran, Aurora, packing maximum sustained winds of 55 kph and gustiness of up to 70 kph, as it moves northeastward at 10 kph.
The tropical cyclone’s weakening has prompted the state weather bureau to lift all Tropical Cyclone Wind Signals (TCWS) previously raised in Bicol Region, Eastern Visayas, and some parts of Mindanao.
PAGASA, meanwhile, lifted all previous gale warning and storm surge advisories but still advises fisherfolk and owners of small marine vessels against sailing due to rough seas over the following coastal waters:
• Up to 4.0 m: The seaboard of Isabela; the eastern seaboard of mainland Cagayan.
• Up to 3.5 m: The seaboard of Batanes, Babuyan Islands, Aurora, and Camarines Norte; the northern seaboards of Camarines Sur and Catanduanes;
• Up to 3.0 m: The seaboards of Ilocos Norte and Ilocos Sur; the northern and eastern seaboards of Polillo Islands; the eastern seaboards of Catanduanes and Northern Samar; the remaining seaboard of mainland Cagayan
Ada is expected to stay within its east northeastward track for the next 24 hours before turning eastward to east southeastward on Tuesday (Jan. 20) until Wednesday (Jan. 21).
Due to its interaction with the northeast monsoon (amihan), the tropical cyclone is forecast to gradually weaken, and may be downgraded into a low pressure area by Wednesday.
