On July 25, 2002, Hurricane Elida in the eastern Pacific reached Category Five status when its winds reached 155 mph (250 km/hr). Elida became the first of three east Pacific Category Five hurricanes to form during that busy season. It was followed by Hurricane Hernan (which became a Cat 5 on sept. 1st) and then Hurricane Kenna (reaching Cat 5 on Oct. 24th). Of this trio, only Kenna made landfall on mainland Mexico, causing over US$100 million in damage and killing four people.
Data from flights into Hurricane Kenna were included in the paper:
