The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued its latest bulletin at 5:00 a.m. on January 19, 2026, confirming that Tropical Storm Ada, internationally named Nokaen, has weakened into a tropical depression while moving over the Philippine Sea east of Luzon.
As of 4:00 a.m., the center of Tropical Depression Ada was located approximately 380 kilometers east of Casiguran, Aurora, near coordinates 16.3°N, 125.7°E. Despite its downgrade in intensity, the weather disturbance continues to influence large portions of northern and eastern Philippines due to its wide wind field and interaction with the Northeast Monsoon.
PAGASA reported that Ada now has maximum sustained winds of 55 kilometers per hour near the center, with gusts reaching up to 70 kilometers per hour. The system maintains a central pressure of 1000 hectopascals and is moving north-northeastward at a relatively slow pace of 10 kilometers per hour. Strong to gale-force winds extend as far as 340 kilometers from the center, affecting areas well outside the cyclone’s core.
At present, no Tropical Cyclone Wind Signal has been raised over any part of the country. However, PAGASA warned that hazardous weather conditions are still expected, particularly due to the combined effects of Ada and the Northeast Monsoon. Strong to gale-force gusts are forecast over several provinces, including Batanes, Cagayan, Isabela, Aurora, parts of the Ilocos Region, Bicol Region, Eastern Visayas, and sections of Mindanao, especially in coastal and upland areas exposed to winds.
Coastal waters are also expected to remain hazardous over the next 24 hours. Rough seas of up to 4.0 meters may affect the eastern seaboard of Isabela and mainland Cagayan, while waves reaching 3.0 to 3.5 meters are forecast over the seaboards of Batanes, Babuyan Islands, Aurora, Polillo Islands, and parts of Bicol. PAGASA strongly advised operators of small seacraft, including motorbancas, to avoid venturing out to sea, particularly those that are ill-equipped or manned by inexperienced crews.
Looking ahead, PAGASA expects Tropical Depression Ada to generally move northeastward before executing a looping track over the sea east of Luzon. Continued intrusion of dry air from the Northeast Monsoon is likely to cause further weakening. The weather system may downgrade into a low-pressure area by Wednesday, January 21, although earlier dissipation remains possible. Residents are advised to stay updated through official PAGASA bulletins and take necessary precautions against adverse weather conditions.
