Hurricane Nora was the first hurricane to a significant danger to the Continental United States since Kathleen in 1976. Part of a tropical wave that contributed to the formation of Hurricane Erika in the Atlantic moved into the Pacific and organized into Tropical Depression 16-E on September 16 and Tropical Storm Nora that same day. Nora became a hurricane in a favourable environment September 18 while moving northwest. Its motion then stalled over an upwelling of cooler water that weakened it. On September 20, Nora again started moving. It reached its peak intensity of 115 knots and 950 mb On September 21 and 22 it moved over the wake of Hurricane Linda. This weakened the storm pack down to a Category 1. During this time, a trough developed that turned Nora to the northeast. This carried Nora over a favourable environment and towards Baja California. After restrengthening slightly, Nora made landfall as a Category 1 hurricane near Punta Eugenia and again south of San Fernando, both times as a hurricane.
