Hurricane Abby made landfall in Cuba, Florida, and North Carolina in June 1968. The first tropical cyclone, first named storm, and first hurricane on the season, Abby developed over the northwestern Caribbean Sea on June 1, as a result of the interaction between a mid-tropospheric trough and a cold front. Moving generally north-northeastward, the depression slowly strengthened while approaching the western tip of Cuba, becoming Tropical Storm Abby late on June 2. Shortly thereafter, Abby made landfall in Pinar del Río Province. The storm dropped heavy rainfall in western Cuba, with up to on Isla de la Juventud. However, no flooding was reported. After reaching the southeastern Gulf of Mexico on June 3, Abby strengthened further and became a Category 1 hurricane on the modern-day Saffir–Simpson hurricane wind scale. However, early on June 4, Abby weakened to a tropical storm. Around midday on June 4, the system made landfall near Punta Gorda, Florida as a strong tropical storm. Initially, Abby weakened slightly after moving inland, but then maintained intensity while tracking slowly eastward across Florida. By midday on June 5, the system emerged into the Atlantic Ocean, but made another landfall near Atlantic Beach late on June 6. The storm weakened slowly weakened and fell to tropical depression intensity over eastern Georgia about 24 hours later. Abby then moved in a parabolic path across The Carolinas, eventually re-emerging into the Atlantic from South Carolina early on June 11. By late on the following day, Abby made another landfall near Swansboro, North Carolina. The storm moved offshore again on June 13, before finally dissipating near the Delmarva Peninsula. Abby's slow movement produced heavy rains across Florida and the Southeastern United States which caused 6 indirect fatalities and $450,000 dollars (1968 USD, $3 million 2013 USD) in damage. ==Meteorological history== A mid-tropospheric trough persisted over the western Caribbean Sea in late May. Around that time, a short-wave trough moving eastward through the Caribbean Sea forced a cold front to move southward into the Straits of Florida. Satellite imagery indicated that the cold front and mid-tropospheric trough began merging as the low-level convergence field increased. Thereafter, barometric pressures in the western Caribbean were decreasing as deep southwesterly flow caused very warm and moist air to enter the area. At 0600 UTC on June 1, the system developed into Tropical Depression One, while situated about northeast of Guanaja, Honduras. When a weak cold front moved into the area, it generated convection, gaining enough organization to be called a tropical depression on June 1. The initial circulation was not embedded within the convection, but as it moved slowly north-northeastward, it was able to strengthen and become better organized, reaching tropical storm strength on the 2nd. It crossed the western tip of Cuba, and upon reaching the southeast Gulf of Mexico Abby achieved hurricane strength. Abby then reached a peak intensity 75 mph (121 km/h) and before weakening back to tropical storm strength.〔National Hurricane Center (1968) (1968 Monthly Weather Review ) URL Accessed: September 20, 2006〕 Abby soon made landfall as a tropical storm near Punta Gorda, Florida on the 4th, and moved across the state. Once it reached the western Atlantic, building high pressure to its east forced Abby northwestward. On the 6th, it again reached the Florida coast, this time near Jacksonville. Abby weakened to a tropical depression as it moved over Georgia, and over the next 6 days, it wandered around the Carolinas, finally dissipating on the 13th east of Virginia. The remnants of Abby were absorbed by a cold front the same day.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hurricane Abby (1968)」の詳細全文を読む スポンサード リンク
