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.
Typhoon Cimaron (2006)
While at its peak strength, Cimaron displayed two small concentric eyewalls, separated by a few kilometres. The storm later made landfall near Casiguran, Aurora in northern Luzon shortly after 1200 UTC on October 29; it became one of the strongest storms to ever hit the region. Interaction with the island's mountainous terrain caused substantial weakening, though Cimaron maintained typhoon status during its 12‑hour crossing. After emerging over the South China Sea on October 30, the system initially maintained its west-northwest course. However, the following day, a weakness developed within the ridge previously steering the typhoon, and Cimaron briefly turned north before essentially stalling. During this time, the system reorganized somewhat and reached a secondary peak intensity with winds of 165 km/h (105 mph) on November 2. While executing a tight clockwise loop, increased wind shear and entrainment of dry air soon caused Cimaron to dramatically weaken. With a new ridge becoming established over China, the weakening system acquired a general southwestward track. Cimaron weakened to a tropical depression on November 4 and ultimately dissipated three days later, just off the coast of southeastern Vietnam.
