According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), a low pressure area formed right outside the Philippine Prevision Area (PAR) on the morning of January 13.
As of 2:00 PM on January 13, the center of the low pressure was at 5.2 degrees north latitude, 134.6 degrees east longitude, about 1,015km southeast of Mindanao.
The low pressure area is medium likely to develop into a tropical storm in the next 24 hours.
PAGASA forecasts that the low pressure will enter PAR later today and may strengthen into the first tropical storm of this year in the next 24 to 48 hours. After formation, the storm will be named locally Ada, meaning "fairy" in Cebuano.
This will be the first time since 2019 that the first storm of the year has formed in January.
Initial forecasts show that Typhoon Ada will move northwest, then change direction or shift northeast near the Samar-Bicol area at the end of the week.
The low pressure trough may cause scattered rain in the eastern areas of Visayas and Mindanao from January 14.
People are advised to continue to follow storm and weather forecasts to learn more about developments.
Meanwhile, the northeast monsoon, broken roads, intertropical convergence zones and humid easterly winds are affecting some areas in the Philippines, causing rain in some places.
