经过凯尔·雷曼和比尔·哈钦森的残余热带风暴雷切尔与美国西部的另一个风暴系统一起，周日继续席卷西部，加剧了南加州几个沿海社区的洪水。
后热带风暴雷切尔星期六晚上在下加利福尼亚登陆，但随着它的移动，西海岸已经感受到它的影响。
雷切尔激起的巨大海浪和部分由于厄尔尼诺增强的开尔文波引起的长期海浪相结合，导致了南加州海岸的大洪水。
受灾最严重的地区之一是奥兰治县的新港海滩，该地区自周五以来一直遭受洪水袭击。
像新港海滩的巴尔博亚大道和许多邻近的街道都被洪水浸泡。
周六，纽波特比奇市宣布当地进入紧急状态，以应对热带风暴雷切尔造成的洪水。
“这一声明将有助于该市获得额外的资源，因为工作人员继续努力保护家园、财产和公共安全，”该市周六在一份声明中说，并补充说，预计高涨的海浪和“异常高的海水水位”将持续整个周末，预计周日将出现最高潮汐。
该市表示，所有城市海滩和新港海滩的码头都已关闭，直至另行通知。
“远离这些地区。洪水和危险的环境带来了严重的安全风险，”该市在声明中建议居民。
热带风暴雷切尔于周六晚些时候在圣地亚哥东南偏南约80英里处变成后热带风暴。然而，它的残余和西部的独立系统将继续加剧西南部分地区的山洪威胁，并在周日和周一带来汹涌的海浪和阵风。
山洪威胁预计将在周日继续展开，对南加州，亚利桑那州西北部，内华达州南部和犹他州西南部的部分地区构成最大风险，那里的山洪威胁级别为3-4级。
美国国家气象局（National Weather Service）从周日下午3点开始向奥兰治县海滩发出沿海洪水警告，并持续到周二下午，警告称，热带风暴雷切尔的残余物可能会引发严重的洪水和海滩侵蚀。
最令人担忧的是周日早上的高潮和热带风暴雷切尔残余的膨胀可能会造成海滩侵蚀和海水再次淹没海滩道路的危险情况。
南加州海岸的其他城市，包括拉古纳海滩、亨廷顿海滩和圣克莱门特，周日向公众分发沙袋，为可能的洪水做准备。
在洛杉矶以南约30英里的海豹滩，警方报告说，“由于对海浪和沿海洪水的担忧”，海滩停车场周日被关闭，“作为保护生命和财产的预防措施。”
周六，热带风暴雷切尔的外围带给南加州和亚利桑那州的部分地区带来了狂风和暴雨。
据报道，雷暴袭击了加利福尼亚州的梅尼费和特梅库拉，风速超过每小时60英里。据报道，这些风暴还带来了1至2英寸的大雨，造成了山洪暴发和泥石流的孤立事件。
周六，阵风还在亚利桑那州凤凰城附近产生了沙尘暴，据报道能见度接近零。
Some California beaches forced to close after ＇unusually high＇ ocean water levels from Tropical Storm Rachel
The remnants ofTropical Storm Rachel， along with a separate storm system over the Western United States， continued to sweep across the West on Sunday， fueling flooding in several Southern California coastal communities．
Post-Tropical Storm Rachel made landfall in Baja California Saturday night， but as it moved in， its impact was already being felt along the West Coast．
A combination of large ocean swells stirred up by Rachel and prolonged swells due in part to an El Niño-enhanced Kelvin wave has produced major flooding along Southern California＇s coast．
One of the hardest-hit areas has been Newport Beach in Orange County， which has been experiencing flooding since Friday．
Main drags like Balboa Boulevard in Newport Beach and numerous adjacent streets have been drenched in floodwaters．
The City of Newport Beach declared a local emergency on Saturday in response to the flooding caused by Tropical Storm Rachel．
＂This declaration will help the City secure additional resources as crews continue working to protect homes， property and public safety，＂ the city said in a statement on Saturday， adding that elevated surf and ＂unusually high ocean water levels＂ are expected to continue through the weekend， with the highest tides anticipated Sunday．
All of the city beaches and piers in Newport Beach are closed until further notice， the city said．
＂Stay away from these areas． Flooding and hazardous conditions pose serious safety risks，＂ the city advised residents in its statement．
Tropical Storm Rachel became post-tropical late Saturday night about 80 miles south-southeast of San Diego． However， its remnants and the separate system over the West will continue to fuel a flash flood threat across portions of the Southwest， as well as bring rough surf and gusty winds， on Sunday and into Monday．
The flash flood threat is expected to continue to unfold on Sunday， with the greatest risk to parts of Southern California， northwest Arizona， southern Nevada， and southwest Utah， where a level 3 of 4 threat for flash flooding is in place．
The National Weather Service issued a coastal flood warning for Orange County beaches that starts at 3 p．m． on Sunday and continues through Tuesday afternoon， warning of potentially significant flooding and beach erosion fueled in part by Tropical Storm Rachel＇s remnants．
The greatest concern is high tide through Sunday morning and swells from the remnants of Tropical Storm Rachel could create dangerous conditions with beach erosion and seawater once again flooding beach roads and paths．
Other cities along the Southern California coast -- including Laguna Beach， Huntington Beach and San Clemente -- were distributing sandbags to the public on Sunday in preparation for possible flooding．
In Seal Beach， about 30 miles south of Los Angeles， police reported that ＂due to elevated surf and coastal flooding concerns＂ beach parking lots were being closed on Sunday ＂as a precaution to protect life and property．＂
On Saturday， the outer bands from Tropical Storm Rachel brought gusty winds and heavy rain to parts of Southern California and Arizona．
Wind gusts of over 60 mph were reported during thunderstorms that hit Menifee and Temecula， California． Heavy rain of up to 1 to 2 inches was reported with these storms as well， causing isolated instances of flash flooding and debris flow．
Gusty winds also produced a dust storm near Phoenix， Arizona， on Saturday with near-zero visibility reported．
