On January 19, an area of low pressure east of the Philippines became sufficiently organised to become Tropical Depression 02W by the JTWC and a tropical depression by the JMA. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) named the system Ambo on the same day. 02W continued towards the west on January 20, however, wind shear increased and convection was soon lost leading the JMA and JTWC to issue their final advisory on it. Meanwhile, PAGASA continued their advisories on Ambo since the depression had a high chance of producing floods in the Philippines. On January 22, the remnants of Ambo produced heavy rains, floods and landslides killing 13 people.
