Tropical Storm Harvey was the final tropical cyclone in a record-breaking string of eight consecutive storms that failed to attain hurricane intensity. The eighth tropical cyclone and eighth named storm of the 2011 Atlantic hurricane season, Harvey developed from a tropical wave in the western Caribbean Sea on August 19. It moved over warm waters in the vicinity of Central America. Later on August 19, the system strengthened into Tropical Storm Harvey while just offshore Honduras. Additional organization occurred and Harvey attained its peak intensity of 65 mph (100 km/h) prior to coming ashore Belize on August 20. Harvey weakened to a tropical depression on August 21, but re-intensified to a tropical storm after emerging into the Bay of Campeche. Early on August 22, it made landfall in Veracruz, then weakened and dissipated several hours later. The precursor disturbance caused thunderstorms throughout the Lesser Antilles, producing squally weather and gusty winds. On Saint Croix in the United States Virgin Islands, gusty winds downed trees, which struck power lines, leaving minor electrical outages. Along its path, Harvey dropped heavy rainfall across much of Central America. Strong winds and heavy precipitation were reported in the country of Belize. Heavy rains in Mexico triggered numerous landslides, one of which killed 3 people. Landslides in damaged 36 homes and 334 homes in the states of Chiapas and Veracruz, respectively. Heavy rainfall also caused rivers to overflow, damaging homes and businesses. Two additional people died in Mexico from unknown causes. ==Meteorological history== A tropical wave exited the west coast of Africa on August 10. The wave was accompanied by a weak center of low pressure and patches of moderate to strong convection. In response, the National Hurricane Center (NHC) noted the potential for the wave to develop into a tropical cyclone. The wave continued westward at and became less vigorous over the next several days, with no strong convection present on August 13. Sporadic convection redeveloped over the course of the following day. Early the next day, the system was analyzed as an area of low pressure between Saint Lucia and Saint Vincent and an inverted trough extending well to the north. The wave moved westward through the Caribbean Sea and produced areas of heavy showers and thunderstorms, although convection on the northern side of the system was limited, possibly a result of excessive Saharan dust. Mid-level cyclonic turning became more pronounced by early on August 17. Although a closed center of circulation was still lacking, conditions were becoming more favorable for the tropical cyclogenesis. By early on August 18, the NHC issued a "high chance" of the wave becoming a tropical cyclone within 48 hours. After a low-level circulation became identifiable, the system was designated as Tropical Depression Eight at 1800 UTC on August 18,〔 while located about east-northeast of Cape Gracias a Dios. Steered by a building high pressure area over the Gulf of Mexico, the cyclone remained on its westward course and was expected to move westward throughout its duration. Continuing to deepen, Tropical Depression Eight strengthened into Tropical Storm Harvey at 1200 UTC on August 19.〔 Harvey continued to strengthen throughout the afternoon, with an improved appearance on visible satellite imagery and good outflow across the northwestern part of the storm. A discussion by the NHC early on August 20 indicated the potential for Harvey to strengthen into a hurricane prior to landfall, but this never materialized.〔 At 0600 UTC on August 20, the storm attained its minimum barometric pressure of . Winds increased slightly further, and at 1730 UTC on August 20, Harvey made landfall near Dangriga, Belize with winds of 65 mph (100 km/h).〔 While located over northeastern Guatemala early on August 21, the system weakened to a tropical depression. Harvey reached the Bay of Campeche early on August 22, where a convective burst allowed it to briefly re-strengthen into a tropical storm. By 0200 UTC, Harvey made landfall near Punta Roca Partida, Veracruz with winds of 40 mph (65 km/h). The system weakened back to a tropical depression at 0600 UTC on August 22. About twelve hours later, Harvey dissipated over Oaxaca.〔 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 Harvey (2011)」の詳細全文を読む スポンサード リンク
