Tropical Storm Fabio was a short-lived tropical cyclone that contributed to a period of heavy rainfall in Hawaii. The fourth named storm of the 2006 Pacific hurricane season, Fabio developed from a tropical wave on July 31 off the southwest coast of Mexico. It maintained a steady westward track throughout its duration, attaining peak winds of 50 mph (85 km/h) before weakening due to wind shear and dry air. The remnants of Fabio passed near Hawaii on August 7 after dissipating the previous day, though no significant damage or deaths were reported. However, rainfall from the system caused flash flooding and left 24 hikers stranded and in need of rescue by helicopter.
