November 2008 Carolinas tornado outbreak : ウィキペディア英語版 | November 2008 Carolinas tornado outbreak
The November 2008 Carolinas tornado outbreak was a brief but deadly tornado outbreak which began shortly after midnight (local time), while many people were sleeping. Most of the eight tornadoes that touched down were produced by two supercell thunderstorms over North Carolina. At 12:25 a.m. EST, the National Weather Service issued a tornado watch for most of eastern North Carolina as the risk of tornadoes increased. Not long after, the first tornado of the outbreak, an EF2, touched down in South Carolina. Almost an hour later, the second tornado touched down in Robeson County, North Carolina. Three other minor tornadoes, two EF0 and an EF1, touched down over the next two hours. Around 3:10 a.m. EST, the first of two killer tornadoes touched down near Kenly, North Carolina. The EF2 tornado destroyed a few homes and damaged several others. Roughly 20 minutes later, an EF3 tornado touched down in Wilson County. This tornado killed one person and injured a few others after destroying several homes. Total damages from the outbreak amounted to $2.4 million, most of which was a result of the EF3 tornado. ==Synopsis==
On November 14, the National Weather Service issued a slight risk of severe weather for the early hours of November 15 for the Carolinas and northern Gulf coast. Although conditions were not favorable for a large-scale severe weather event, the possibility of small clusters of thunderstorms existed. Strong wind shear was forecast to persist, which would allow small bow-echo line of thunderstorms which could produce damaging winds. The result of a weak disturbance which passed through the area of slight risk lowered the chances of tornadic thunderstorms developing. At 12:25 a.m. EST, the Storm Prediction Center (SPC) issued a Tornado watch for most of eastern North Carolina. A broken line of thunderstorms had already developed and the risk of tornadoes greatly increased, with the chances of an EF2 or stronger touching down reaching 20%. The first tornado touched down shortly after in South Carolina.〔 Over the following several hours, two supercell thunderstorms spawned seven more tornadoes throughout North Carolina. The final tornado dissipated around 4:36 a.m. EST, just 3 hours and 46 minutes after the outbreak started.〔 The tornado watch remained in effect until before being cancelled at 8:00 a.m. EST.〔
