拉斯维加斯谷地暴雨引发山洪：Henderson三起激流救援一人死亡
10月30日午间，一场强对流暴雨袭击内华达州克拉克县的拉斯维加斯谷地，国家气象局（NWS）对包括拉斯维加斯大道、Fremont 街与 Henderson 在内的大片地区发布山洪警报。Henderson 市消防人员在该市三处地点展开激流救援，共救出4人，其中一名在排水渠中获救的男子随后心脏骤停，送医后不治。
据 Henderson 市府发言人向媒体通报，三起救援约在下午1时同时发生，两起位于 Lake Mead Parkway 一带：两人被从一辆被洪水冲离路面的汽车中救出，一人爬上一辆被困车辆的车顶获救；第三起发生在 North Milan Street 附近。暴雨还带来乒乓球大小的冰雹，Henderson 东部部分地区降雨量约达1.5英寸，Lake Mead Parkway 东段因泥石与杂物一度封闭。
拉斯维加斯哈里·里德国际机场因雷电一度实施地面停飞，航班平均延误约15至23分钟；NV Energy 一度报告超过4,000户用户停电。气象局表示，一个新的风暴系统周六晚至周一还将给包括南内华达在内的美国西南部多州带去更多降雨，已发布洪水监视，土壤饱和地区须防范新的山洪。
Flash Floods Strike Las Vegas Valley: Three Swift-Water Rescues in Henderson, One Dead
A fast-moving thunderstorm system struck the Las Vegas Valley in Clark County, Nevada, around midday on October 30, triggering flash flood warnings across the Strip, downtown Las Vegas and Henderson. Fire crews in Henderson carried out three simultaneous swift-water rescues at about 1 p.m., pulling four people from floodwaters; one man rescued from a drainage wash went into cardiac arrest and died at a hospital, according to a city spokesperson.
Two of the rescues took place along Lake Mead Parkway, where floodwaters swept one vehicle off the roadway and left another driver stranded on a car roof. The storm also dropped hail as large as ping-pong balls, dumped an estimated 1.5 inches of rain on parts of east Henderson and forced the closure of Lake Mead Parkway east of Lake Las Vegas Parkway due to mud and debris.
Lightning prompted a ground stop at Harry Reid International Airport, and NV Energy reported more than 4,000 customers without power at the peak. The National Weather Service has issued flood watches for much of the Southwest through Monday as another storm system approaches.
