2006 Pacific typhoon season
The 2006 Pacific typhoon season was a near-average season that produced a total of 23 named storms, 15 typhoons, and six super typhoons. The season ran throughout 2006, though most tropical cyclones typically develop between May and October. The season's first named storm, Chanchu, developed on May 9, while the season's last named storm, Trami, dissipated on December 20. Also, this season was more active, costly, and deadly than the previous season.
2015 Pacific typhoon season
Tropical Depression 01W developed during January 13, to the south of Chuuk State. Despite convection being displaced from its exposed low-level circulation center (LLCC), the JMA upgraded 01W to a tropical storm with the name "Mekkhala", the first of the season. Later, the PAGASA had stated that Mekkhala had entered the Philippine Area of Responsibility, assigning it the local name "Amang". By January 15, the JTWC upgraded Mekkhala to a tropical storm when spiral banding wrapped into a defined LLCC. Mekkhala intensified to a severe tropical storm when deep convection wrapped into its center during January 16. Satellite imagery revealed that a central dense overcast had obscured its center, therefore Mekkhala strengthened into a Category 1 typhoon by the JTWC. Operationally the JMA classified Mekkhala's peak as a typhoon on January 17, however in post-analysis Mekkhala reached its peak as a severe tropical storm. At the time when Mekkhala made landfall over in Eastern Samar, Visayas, land reaction persisted and the typhoon weakened to a tropical storm. By January 18, Mekkhala continued weakening as it started to "unravel and erode" as it passed through the Bicol region in Luzon. Both the JMA and the JTWC issued their final warning later that day. However, the JMA continued to monitor Mekkhala until it dissipated early on January 21.
