Hurricane Cindy impacted the Carolinas, the Mid-Atlantic states, New England, and the Canadian Maritime Provinces during the 1959 Atlantic hurricane season. The third storm of the season, Cindy originated from a low-pressure area associated with a cold front located east of northern Florida. The low developed into a tropical depression on July 5 while tracking north-northeastward, and became Tropical Storm Cindy by the next day. Cindy turned westward because of a high-pressure area positioned to its north, and further intensified into a weak hurricane off the coast of the Carolinas on July 8. Early on July 9, Cindy made landfall near McClellanville, South Carolina, and re-curved to the northeast along the fall line as a tropical depression. It re-entered the Atlantic on July 10, quickly restrengthening into a tropical storm while it began to move faster. On July 11, Cindy passed over Cape Cod, while several other weather systems helped the storm maintain its intensity. Cindy transitioned into an extratropical cyclone on July 12 as it neared the Canadian Maritime Provinces. Overall structural damage from Cindy was minimal. One driver was killed in Georgetown, South Carolina after colliding with a fallen tree, and five indirect deaths were caused by poor road conditions wrought by the storm in New England. Many areas experienced heavy rains, and several thousand people evacuated. Other than broken tree limbs, shattered windows and power outages, little damage occurred. Cindy brought a total of eleven tornadoes with it, of which two caused minor damage in North Carolina. The heaviest rainfall occurred in north central South Carolina, where rainfall amounted to . Tides ranged from above normal along the coast. As drought-like conditions were present in the Carolinas at the time, the rainfall produced by Hurricane Cindy in the area was beneficial. After becoming extratropical over the Canadian Maritimes, the cyclone produced heavy rains and strong winds that sunk one ship. Damage caused by Cindy was estimated at $75,000 (1959 USD). == Meteorological history == The origins of Cindy can be attributed to a deepening low-pressure area that tracked from the Great Lakes as a related cold front traveled southeastward and became stationary over the Atlantic, extending from northern Florida to Bermuda. On July 5, the front spawned a separate cut-off cold-core low off the coast of the Carolinas. This complex scenario resulted in the formation of a tropical depression later during the day, which slowly meandered north-northeastward. Tropical cyclones of this origin typically remain at a small size and evolve slowly, and Cindy complied to this pattern.〔 Convection began to increase on July 6, supported on the basis that many showers were observed to the north of the depression. An anticyclone—a large mass of air rotating clockwise—intensified within the depression's vicinity, resulting in a tighter pressure gradient and increasing winds to the north of the center of the depression.〔 The depression intensified into Tropical Storm Cindy early on July 7,〔 and a reconnaissance flight into the storm late during the afternoon observed maximum sustained winds of 60–65 mph (95–100 km/h) and a minimum pressure of 997 mbar (hPa; 29.44 inHg).〔 Cindy began to curve westward late on July 7 as it reached peak intensity, with a minimum central pressure of 996 mbar (hPa; 29.41 inHg), and drifted due west early on July 8 as a result of a maturing surface high to its north.〔 Steady intensification continued throughout the day, and the storm attained hurricane status during the morning of July 8.〔 At approximately 2:45 UTC on July 9,〔 the hurricane made landfall near McClellanville, South Carolina. Shortly thereafter, Cindy began re-curving northwestward along the fall line,〔 and eventually weakened to a tropical depression. The depression abruptly turned toward the east-northeast over North Carolina during the afternoon hours of July 9. Cindy then began to accelerate as it curved slightly towards the northeast, and eventually regained tropical storm status late on July 10 as it emerged into the Atlantic. Cindy scraped the southern fringe of the Delmarva Peninsula near the mouth of the Chesapeake Bay at approximately 00:00 UTC on July 11, and rapidly traveled northeastward during the day. Cindy passed over Cape Cod near the mid-morning of July 11,〔 during which a series of shortwave troughs passed near the storm, producing high-level outflow that helped Cindy maintain intensity.〔 Later on July 11, Cindy moved ashore in New Brunswick and made landfall over Prince Edward Island the following day. The storm subsequently moved over Quebec and Labrador, where it transitioned into an extratropical cyclone.〔 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 Cindy (1959)」の詳細全文を読む スポンサード リンク
