The 2006 Central Pacific cyclone, also called 91C.INVEST or Storm 91C, was a strange weather event in 2006. Forming on October 30 from a mid-latitude cyclone in the north Pacific mid-latitudes, it moved over waters warmer-than-normal. It got some characteristics more normal for subtropical or even tropical cyclones. However, as it came closer to western North America, it fell apart. Moisture from its remains then caused a lot of rainfall in British Columbia.
