Hurricane Lane was a powerful tropical cyclone that brought torrential rainfall and strong winds to Hawaii during late August 2018. The storm was the wettest on record in Hawaii, with peak rainfall accumulations of along the eastern slopes of Mauna Loa. Lane was the twelfth named storm, sixth hurricane, fourth major hurricane, and the first of three Category 5 hurricanes of the record-breaking 2018 Pacific hurricane season. The cyclone originated from an area of low pressure that formed well southwest of Mexico on August 13. Tracking west through a region of favorable atmospheric and oceanic conditions, the system steadily intensified over the following days. It reached an initial peak as a Category 4 hurricane on August 18. Temporarily inhibited by more hostile conditions, the hurricane weakened slightly before regaining strength and reaching Category 5 status on August 22 to the south of Hawaii. Lane peaked with winds of 160 mph (260 km/h) and a barometric pressure of 926 mbar (hPa; 27.34 inHg). Thereafter, the hurricane turned north and slowed. During this period, torrential rains battered much of the Hawaiian Islands. Unfavorable conditions again affected the hurricane, and it degraded to a tropical depression by August 28 before dissipating the following day.
