热带风暴Rachel残余袭拉斯维加斯：机场降雨1.08英寸破当日纪录，多条道路积水封闭
拉斯维加斯消息——据国家气象局拉斯维加斯办公室的警报与本地媒体10月11日报道，热带风暴“雷切尔”（Rachel）残余水汽当天深入莫哈韦沙漠，拉斯维加斯谷地遭遇山洪：哈里·里德国际机场录得1.08英寸降雨，打破该站当日降雨纪录；谷地西部与西北部部分雨量计测得2.5英寸以上。国家气象局清晨对克拉克县中西部、包括拉斯维加斯大道一带发布山洪警告，雷达估测警告区内降雨约1.5至3英寸。
积水迅速涌上道路。据本地交通与媒体汇总，内华达—加利福尼亚州界附近I-15旁的普里姆大道（Primm Boulevard）全线封闭，弗拉明戈路与科瓦尔巷（Koval Lane）一带、温尼克大道（Winnick Avenue）等路段因积水与杂物受阻，215号公路查尔斯顿大道附近有车辆受困，消防人员多次实施激流救援。拉斯维加斯大道附近的LINQ长廊一带也出现水流漫过街面的画面。
气象部门提醒，沙漠地面与城市硬化路面几乎不吸水，短时强降雨会在数分钟内汇入排水渠与低洼路口，驾车者切勿驶入积水路段。这场雨是内华达州10月11日的州内头条：一个热带系统的残余，给全美最干旱的大城市之一送来了七年多来最湿的一天。洪水警戒延续至10月12日清晨，其后天气预计逐步转干。

Rachel's Remnants Soak Las Vegas: Record 1.08 Inches at the Airport, Roads Flooded and Closed
LAS VEGAS — Moisture from the remnants of Tropical Storm Rachel pushed deep into the Mojave Desert on October 11, triggering flash flooding across the Las Vegas Valley, according to National Weather Service Las Vegas warnings and local reporting. Harry Reid International Airport measured 1.08 inches of rain, breaking the station's daily record, while gauges in the western and northwestern valley topped 2.5 inches. The Weather Service issued a morning flash flood warning for west-central Clark County, including the Las Vegas Strip area, with radar-estimated totals of roughly 1.5 to 3 inches in the warned area.
Water quickly covered roads. Local traffic and media reports said Primm Boulevard at Interstate 15 near the California state line was closed in all lanes; flooding and debris blocked roads around East Flamingo Road and Koval Lane and at Winnick Avenue; drivers were stranded in standing water on the 215 at Charleston Boulevard; and firefighters carried out repeated swift-water rescues. Water also rushed through streets near the LINQ Promenade on the Strip corridor.
Forecasters reminded residents that desert soil and paved surfaces absorb almost nothing, so intense rain can fill washes and low crossings within minutes, and drivers should never enter flooded roads. For Nevada, it was the state's top story on October 11: the remnants of a tropical system delivered one of the driest big cities in America its wettest day in more than seven years. A flood watch ran into Monday morning before drier weather returned.
