Prior to impacting the Philippines, Public Storm Warning Signals #3 and #4, the two highest levels, were raised for several provinces in Luzon.

In contrast to the typhoon's extreme intensity, damage was somewhat limited in the Philippines due to the lower population density of the affected areas.

[nb 1] Winds along the periphery of Cimaron fanned a large wildfire near Hong Kong, and moisture from it fueled record-breaking rains in British Columbia, Canada.

On October 24, 2006, an area of disturbed weather, characterized by flaring convection around a low-level circulation, developed approximately 595 km (370 mi) east of Guam.

[1][5][nb 3] Several hours later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigned the storm the local name Paeng as was within their area of responsibility.

At the end of this phase on October 29, Cimaron attained its peak intensity with winds of 185 km/h (115 mph) and a barometric pressure of 920 mbar (hPa; 27.17 inHg).

[3] The JTWC estimated Cimaron to have been a stronger system, attaining its peak intensity as a Category 5-equivalent super typhoon with one-minute winds of 260 km/h (160 mph).

Additionally, a forecaster at SAB noted that the lower estimates were likely due to restrictions on the Dvorak technique stemming from Cimaron's rapid intensification.

Interaction with the island's mountainous terrain caused substantial weakening, though Cimaron maintained typhoon status during its 12‑hour crossing.

However, the following day, a weakness developed within the ridge previously steering the typhoon, and Cimaron briefly turned north before essentially stalling.

[3] While executing a tight clockwise loop, increased wind shear and entrainment of dry air soon caused Cimaron to dramatically weaken.

[3][5] By October 28, Isabela, southern Cagayan, Quirino, and northern Aurora provinces were placed under Public Storm Warning Signal (PSWS) #3, the second-highest level.

[9] During a national radio broadcast President Gloria Macapagal Arroyo urged residents to heed warnings and not to venture out during the storm.

[10] Throughout Luzon, schools and government offices were closed on October 29 while residents in mountainous areas were urged to evacuate due to threat of mudslides.

[11] The National Transmission Corporation deployed power restoration crews across the region to allow for quick post-storm response.

[13] Authorities began evacuating residents in flood-prone areas along the coast from Quảng Bình Khánh Hòa,[14] including 12,500 in Thừa Thiên-Huế Province.

Many reservoirs in the nation were above 80 percent capacity and further heavy rains would lead to a major flood event; the main concerns were for the Bhumibol and Sirikit dams in Tak and Uttaradit provinces, respectively.

[20] By November 1, approximately 20,000 fishing vessels returned to port as conditions over the South China Sea deteriorated; shipping over the Qiongzhou Strait remained unaffected.

[29] Though the storm remained over open waters after moving over the South China Sea, strong winds stemming from it fanned a large wildfire in Tai Lam Country Park, Hong Kong.

[33] Moisture from the typhoon also fed an extratropical cyclone, in an atmospheric river known as the Pineapple Express,[2] that brought heavy rains to southern British Columbia, Canada, prompting flood watches for the region[34][35] Southern areas of the province were deluged by the storm, with some areas receiving 250 to 300 mm (9.8 to 11.8 in) of rain.

[27] Teams from the Red Cross were already deployed in the Philippines due to Typhoon Xangsane in September and were able to quickly respond in Cimaron's aftermath.

On December 11, President Arroyo declared a national state of calamity and released 1 billion PHP (US$25.6 million) in relief and rehabilitation funds.
