Why Record-Breaking Hurricane Trio Swirls Above the Pacific

A parade of tropical storms traipses across the Pacific in a new satellite image showing the once-in-a-lifetime (or more than one lifetime) event. Kilo, Ignacio and Jimena were all Category 4 hurricanes when these mosaic images over Hawaii were made on Aug. 29 and 30. Category 4 storms have winds ranging from 130 to 156 mph (209 to 251 km/h) — strong enough to uproot trees and severely damage structures, according to the National Weather Service.
