Hurricane Danny (1985)
Hurricane Danny produced 13 significant tornadoes in the Southern United States during August 1985, the most spawned by a tropical cyclone until Hurricane Ivan in 2004. The fourth named storm and third hurricane of the season, Danny developed from a tropical wave in the northwestern Caribbean Sea on August 12. The system moved northwestward and initially remained weak. Early on August 13, it brushed Cape San Antonio, Cuba before emerging the Gulf of Mexico later that day. The system then intensified into Tropical Storm Danny on August 14. Danny deepened further and became a hurricane early on the following day, while beginning to re-curve north-northwestward. Late on August 16, Danny attained its peak intensity with winds of 90 mph (150 km/h). Shortly thereafter, the storm made landfall near Grand Chenier, Louisiana at the same intensity. Early on August 17, Danny weakened to a tropical storm and was downgraded to a tropical depression several hours later. It moved east-northeastward across the Southeastern United States, until dissipating over southeastern Virginia on August 18.
There was widespread coastal and inland flooding in Louisiana. The storm brought up to of precipitation to Kentwood. Additionally, there were two tornadoes reported in the state. Overall, 33 single-family homes and 26 mobile homes were destroyed, while three condos, 908 single-family houses and 265 mobile homes were damaged. A combination of rainfall and storm surge in southern Mississippi caused severe beach erosion and flooded 70 homes in Hancock County alone. Further north, a tornado in Enterprise severely damaged six homes, three barns, and two roofs; it also destroyed one house. In Alabama, the storm spawned 34 tornadoes, which destroyed 27 single-family residences and 18 mobile homes. About 90 homes, eight mobile homes, and 23 businesses suffered damage. Impact was similar but less severe in several other states, including Georgia, Maryland, South Carolina, Texas, and Virginia. Danny caused five fatalities and about $100 million in damage (1985 USD).
==Meteorological history==
A tropical wave emerged into the Atlantic Ocean from the west coast of Africa on July 30. The system moved westward traversed the Atlantic Ocean and did not have any significant convection – shower and thunderstorm activity – until after crossing the Windward Islands and entering the Caribbean Sea. By the time the system reached the central Caribbean on August 10, it was analyzed as a broad low-pressure area. After a United States Air Force reconnaissance aircraft investigated the area early on August 12, data indicated that Tropical Depression Four developed at 0000 UTC, with its poorly defined atmospheric circulation located near the Cayman Islands. The depression initially struggled to intensify and moved northwestward, crossing over Grand Cayman during the daytime on August 12 and striking Cape San Antonio, Cuba early on August 13.
After landfall at the western tip of Cuba, the depression entered the Gulf of Mexico later on August 13 and began to strengthen. Early on the following day, the depression was upgraded to Tropical Storm Danny. Thereafter, it deepened fairly quickly and became a Category 1 hurricane on the Saffir–Simpson hurricane wind scale. Danny initially continued northwest, but turned north early on August 15, before making landfall near Lake Charles. Shortly before landfall, Danny reached a peak wind speed of 90 mph (150 km/h) and minimum barometric pressure of 987 millibars (29.15 InHg). The system then quickly weakened into a tropical storm while moving inland. The center remained identifiable as a tropical depression before transitioning into extratropical cyclone and merging with a cold front near the East Coast of the United States on August 20.〔
