High Quality Content by WIKIPEDIA articles! Tropical Storm Ignacio was a weak tropical cyclone that existed during August 1997. The 12th tropical cyclone and 9th named storm of the 1997 Pacific hurricane season, Ignacio formed west of Mexico from a weather disturbance embedded within a more broad system. It was classified as a tropical depression on August 17, and although it quickly intensified into a tropical storm, harsher environmental conditions caused it to begin weakening as the cyclone moved northward. On August 19, Ignacio transitioned into an extratropical cyclone as it approached California, where its remnants produced unprecedented August rainfall, numerous traffic accidents, and 78,000 power outages.
