High Quality Content by WIKIPEDIA articles! Tropical Storm Lidia was a deadly, destructive tropical cyclone that occurred during the 1981 Pacific hurricane season. It resulted in more casualties and caused greater damage than Hurricane Norma, which took place later that season. On October 6, a tropical depression formed and strengthened into a tropical storm six hours later. Lidia brushed the Gulf of California coast of Baja California Sur and made landfall just south of Los Mochis in Sinaloa on October 8. Tropical Storm Lidia rapidly weakened and dissipated the same day. Lidia killed at least 73 people and caused at least $80 million (1981 USD) which is equivalent to $193 million (2010 USD) in damage. It inflicted heavy rain and flooding throughout parts of northwestern Mexico, especially Sinaloa.
