typhoon - a tropical cyclone occurring in the W Pacific or Indian oceans
hur·ri·cane - A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean, traveling north, northwest, or northeast from its point of origin, and usually involving heavy rains.
So location is the issue, but I was slightly wrong on how. And thus a Eastern Pacific tropical cyclone with enough wind speed is in fact correctly called a hurricane.
