Tropical Storm Henri was a weak tropical storm that formed in the 2003 Atlantic hurricane season. The eighth storm of the season, Henri was one of six tropical cyclones to hit the United States in the year. Henri formed from a tropical wave in the Gulf of Mexico in early September, and crossed over Florida as a tropical depression. Its remnants later moved into the Mid-Atlantic before dissipating completely. Henri caused little damage as a tropical cyclone. In Florida, it dropped heavy rainfall, though damage was limited to minor flooding damage. In Delaware and Pennsylvania, damage was greater, where heavy rainfall damaged hundreds of houses and businesses. The resulting floods in Delaware were described as a 1 in 500 year event. The total damage by Henri along its path amounted to $19.6 million (2003 USD, $21.5 million 2006 USD), but no deaths were reported. == Meteorological history == On August 22, a tropical wave moved off the coast of Africa, and it moved westward across the Atlantic Ocean and Caribbean Sea without developing significantly. On September 1 the wave axis entered the Gulf of Mexico, and upon doing so convection steadily organized around a low-level center of circulation. The system moved northward and developed into Tropical Depression Twelve on September 3 while located about 300 miles (480 kilometers) west of Tampa, Florida. Embedded within a slow mid-latitude trough, the depression moved eastward and strengthened into Tropical Storm Henri on September 5. Despite strong southwesterly vertical shear, Henri continued intensifying while moving eastward, and reached a peak strength of 60 mph (95 km/h) later on September 5. Shortly thereafter, though, the shear greatly weakened the storm, and it was downgraded to a tropical depression. Henri was not able to recover its intensity, and made landfall near Clearwater, Florida on September 6 as a 35 mph (55 km/h) tropical depression, and quickly crossed the state as it accelerated to the northeast.〔 Despite initial predictions of re-intensification over open waters due to potentially lower shear, Henri failed to re-strengthen and degenerated into a remnant low pressure area on September 8 off the coast of North Carolina.〔 The broad and disorganized remnant low remained nearly stationary due to a ridge of high pressure to its north.〔 Residual convection within the remnants of Henri remained disorganized, but forecasters kept watch for the potential for redevelopment. However, it moved inland near Cape Hatteras on September 12 without reorganizing. The remnants continued to the north and dissipated on September 17 over New England. 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「Tropical Storm Henri (2003)」の詳細全文を読む スポンサード リンク
