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.

Just hours later, the JMA upgraded Chebi from severe tropical storm with 10-minute sustained winds of 55 knots to a typhoon with winds of 95 knots, with a pressure decrease of 40 hPa over three hours. The JTWC followed suit, upping Chebi from a tropical storm with 1-minute sustained winds of 55 knots to a Category 4-equivalent typhoon at 9 a.m. UTC. PAGASA raised Public Storm Warning Signal No. 4 for three provinces in Luzon, making Chebi the second storm (Typhoon Cimaron served as the first one that year.) in as many weeks to force a Signal #4. After rapidly deepening, Chebi weakened as it approached the Philippines. It made its first landfall near Casiguran, Aurora early on November 11, crossed the Lingayen Gulf and its second landfall on Barangay Lucap, Alaminos City about 8 hours later.
