The 1990 Atlantic hurricane season was the most active Atlantic hurricane season since 1969, with a total of 14 named storms. The season also featured eight hurricanes, one of which intensified into a major hurricane. It officially began on June 1, 1990, and lasted until November 30, 1990. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, tropical cyclogenesis can occur prior to the start of the season, as demonstrated with Tropical Depression One, which formed in the Caribbean Sea on May 24. Though very active, the season featured relatively weak systems, most of which stayed at sea. The 1990 season was unusual in that no tropical cyclone of at least tropical storm strength made landfall in the United States for the first time since the 1962 season, although Tropical Storm Marco weakened to a depression just before landfall. There have been a total of six such seasons in which no cyclones of at least tropical storm intensity have made landfall in the United States – 1853, 1862, 1864, 1922, 1962, and 1990 seasons. Only a few tropical cyclones caused significant impacts. Hurricane Diana killed an estimated 139 people in the Mexican states of Veracruz and Hidalgo, while also causing approximately $90.7 million in damage. Hurricane Klaus brought flooding to Martinique and caused torrential rainfall across the southeastern United States after combining with Tropical Storm Marco and a frontal boundary. As a result of effects from Diana and Klaus, both names were retired following the season. Overall, the storms of the season collectively caused 171 fatalities and approximately $157 million in damage. Seasonal forecasts Pre-season forecasts Forecasts of hurricane activity are issued before each hurricane season by noted hurricane experts such as Dr. William M. Gray and his associates at Colorado State University (CSU). A normal season as defined by the National Oceanic and Atmospheric Administration (NOAA), has eleven named storms, of which six reach hurricane strength, and two major hurricanes. In April 1990, it was forecast that six storms would reach hurricane status, and there would be "three additional storms" from the previous year, which would indicate 14 named storms. The forecast did not specify how many hurricanes would reach major hurricane status. In early June 1990, CSU released their predictions of tropical cyclonic activity within the Atlantic basin during the 1990 season. The forecast from CSU called for
