Tropical Storm Dean was a short-lived storm that formed in late July 1995 and lasted into early August.〔 It was the fourth named storm of the 1995 Atlantic hurricane season. It spent most of its life as a tropical depression, and briefly gained tropical storm status before its landfall on the Texas coast on July 30. After landfall, it dissipated over central Texas on August 2.〔 The impacts from Dean were minimal, mainly due to heavy rain in Oklahoma and Texas that caused localized coastal and inland flooding.〔 Two F0 Tornadoes touched down in Texas as a result of Dean's landfall.〔 Also, Twenty families had to be evacuated in Chambers County, due to flooding in the area.〔 One fatality was recorded as a result of flooding in Oklahoma.〔 Several highways were flooded out in Oklahoma, which impeded travel in the state.〔 In addition approximately $500,000 (1995 U.S. dollars) worth of damage was recorded in the aftermath of Dean. ==Meteorological history== The precursor system that would form Dean was a stationary front situated in the northeastern Gulf of Mexico in the last week of July. On July 27, it developed a weak upper-level circulation indicated by reports from buoys in the Gulf, its structure was disorganized but was in the process of organizing. The system continued to organize early on July 28, and that afternoon it developed a surface circulation. The tropical depression that spawned Dean was thought to have formed at around 1800 UTC, July 28. It was later declared Tropical Depression Four that same day with the center located about 345 miles (555 km) southeast of New Orleans.〔 At first, the depression slowly tracked westward because it was blocked by a ridge of high pressure to the north. The system was under frequent reconnaissance surveillance, and the depression remained poorly organized and continued to be at tropical depression status well into 29 July.〔 The organization of the system hindered further development despite favorable conditions with low wind shear and warm sea surface temperatures. Late on July 29, the system began to execute a turn to the northwest with an increase in forward speed. It still remained a poorly organized tropical depression south of Louisiana. On July 30, the system's circulation began to organize and the first reports of tropical storm-force squalls were reported as it moved closer to the Texas coast. Based on this the National Hurricane Center (NHC) issued tropical storm warnings for much of the Texas and Louisiana coast, from Intracoastal City, Louisiana to Corpus Christi, Texas. Later that afternoon it strengthened into Tropical Storm Dean while located just 70 mi (110 km) off the coast.〔 The Hurricane Hunters confirmed that Dean strengthened in the final hours before its landfall on the Texas coast to a 45 mph (75 km/h) storm, and made landfall near Freeport, Texas at 8:30 pm CDT (0130 UTC) July 31. Shortly after its landfall, Dean weakened back to tropical depression strength as it tracked further northwest into Texas. The depression stalled in central Texas on August 1 and remained there for 36 hours until the next day, dropping heavy rain over parts of the state. Late on August 2, it merged with a non-tropical front and dissipated.〔〔 The remnants of Dean eventually moved up into Oklahoma, where it caused heavy rainfall, forcing roads to close and rescues to be made.〔 Dean also dropped heavy rain across the Midwest states as well. Some areas in Kansas received more than seven inches of rain. Illinois, Missouri, and Indiana each had areas that received more than 5 inches (127 mm) of rain from Dean.〔 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 Dean (1995)」の詳細全文を読む スポンサード リンク
