Hurricane Gilma was one of the most intense Eastern Pacific tropical cyclones on record and the second of three Category 5 hurricanes during the active 1994 Pacific hurricane season. Developing from a westward tracking tropical wave over the open waters of the eastern Pacific Ocean on July 21, the pre-Gilma tropical depression was initially large and disorganized. Gradual development took place over the following day before rapid intensification began. By July 23, the storm intensified into a hurricane and later a Category 5 storm on July 24. As Gilma reached this intensity, it crossed into the Central Pacific basin, the fourth consecutive storm to do so.
The storm peaked early on July 24 with winds of 160 mph (255 km/h) and a barometric pressure estimated at 920 mbar (hPa; 27.17 inHg). The following day, unknown factors caused the storm to suddenly weaken before increasing wind shear took over. The storm gradually weakened for the duration of its existence, turning slowly to the northwest. Late on July 28, the storm brushed Johnston Atoll, bringing gusty winds and light rainfall to the region. Gilma persisted until July 31 at which time it was downgraded to a tropical depression and dissipated over open waters.
