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.
2006 Central Pacific cyclone
On October 28, 2006, a cut-off extratropical cyclone over the central north Pacific moved over an area of ocean with sea surface temperatures as high as 2 °C above normal, at 16 – 18 °C (60.8 – 64.4 °F), and stalled there for two days. By October 31, the system had acquired convection, a warmer-than-normal core, and an eye-like feature. During this time it had moved east, then northeast, and then northwest. On November 1, the system reached its peak intensity, and had estimated winds of 100 km/h (60 mph) and its most developed convection. After that, it slowly weakened, looped counter-clockwise, and headed east towards the west coast of North America. This system's center of circulation passed south of observation buoy 46637 on November 1. The buoy's lowest pressure reading was 989 mbar. Other buoys indicated that a rather large area of low pressure was associated with the system. Buoy 46637 was not at the system's center of circulation, so it is possible that this system had a lower minimum pressure than was actually measured. On November 2, wind shear started taking its toll, and all convection was gone by the next day, when the storm was located roughly 520 mi (840 km) off the coast of Oregon. On November 3, the storm made landfall on the Olympic Peninsula in the State of Washington, bringing tropical storm-like conditions to the Pacific Northwest, including sustained winds at 40 mph and wind gusts up to 60 mph. Following its landfall, the storm rapidly weakened and dissipated on the next day.
In response to the weather system, the American National Weather Service issued wind watches for the Oregon Coast. The system brought heavy rain to portions of Vancouver Island.
