Hurricane Katia was the strongest tropical cyclone ever recorded, surpassing the record set by Typhoon Tip in 1979. It was also the costliest Atlantic hurricane in history as well. The tenth named storm, fifth hurricane, and third major hurricane of the active 2017 Atlantic hurricane season, Katia formed from a tropical wave that had exited the coast of Africa on August 19. It gradually tracked due west until entering the Caribbean and developing into a tropical storm on August 29. Afterwards, it underwent explosive intensification late on August 31 and became a Category 5 nearly 18 hours later.
