布赖恩·K·沙利文 从宾夕法尼亚州到佛罗里达州，超过44万户家庭和企业停电，全国两端洪水威胁正在加剧，美国正面临来自大西洋风暴伊萨亚斯残留和从太平洋移入西南部的热带风暴瑞秋的罕见双重热带威胁。
More than 440,000 homes and businesses from Pennsylvania to Florida are without power and flood threats are rising at both ends of the country as the US deals with a rare double tropical threat from the remnants of storms Isaias off the Atlantic and Rachel moving into the Southwest from the Pacific.
在东部，根据PowerOutage.com的数据，伊萨亚斯残留在周日凌晨穿越田纳西州时，有441,749户家庭和企业停电。该风暴周五晚上以二级飓风登陆，根据阿拉巴马州官员和佛罗里达州州长罗恩·德桑蒂斯的Facebook帖子，已造成至少四人死亡。
In the East, there were 441,749 homes and businesses without power as the remnants of Isaias moved across Tennessee early Sunday, according to PowerOutage.com. The storm came ashore Friday night as a Category 2 hurricane and has killed at least four people, according to Facebook posts by officials in Alabama and Governor Ron DeSantis in Florida.
与此同时，在美国西部，热带风暴瑞秋的残留正穿越南加州，从南爱达荷州延伸至墨西哥下加利福尼亚州，洪水风险正在上升，美国国家飓风中心表示。犹他州超过9500户客户停电，PowerOutage.com称。
Meanwhile in the West, the remnants of Tropical Storm Rachel are racing across Southern California and raising flood risks from southern Idaho to Mexico’s Baja California, the US National Hurricane Center said. Across Utah, more than 9,500 customers were without power, PowerOutage.com said.
来自瑞秋的强降雨核心正向拉斯维加斯以西地区带来洪水威胁，并已在死亡谷发布警报，商业天气预报公司AccuWeather Inc.的气象学家丹·佩迪诺夫斯基表示。
A core of heavy rain from Rachel is bringing flood threats to the area west of Las Vegas and has raised warnings in Death Valley, said Dan Pydynowski, a meteorologist with commercial forecaster AccuWeather Inc.
美国同时被两岸热带系统“夹击”的情况“罕见但并非前所未有”，佩迪诺夫斯基说。“这当然不是每年都会发生，也不是常见现象，但确实会发生。”2021年，飓风艾达袭击路易斯安那州，而墨西哥海岸飓风诺拉的水汽导致亚利桑那州出现洪水性降雨，佩迪诺夫斯基称。类似情况也发生在1992年，当时飓风安德鲁袭击佛罗里达州，而太平洋上的飓风莱斯特穿越美国西南部。
For the US to get squeezed by tropical systems on both coasts at the same time is “rare, but not unheard of,” Pydynowski said. “It certainly doesn’t happen every year and it is not common per se, but it does happen.”In 2021, Hurricane Ida struck Louisiana, while moisture from Hurricane Nora off Mexico led to flooding rains across Arizona, Pydynowski said. A similar situation happened in 1992 when Hurricane Andrew slammed Florida and Hurricane Lester off the Pacific tracked through the US Southwest.
南部的飓风西蒙，风速达每小时150英里，使其成为萨菲尔-辛普森五级等级中的四级风暴，美国飓风中心表示，该飓风正以其最强的风力之一袭击墨西哥哈利斯科州和科利马州的海岸。该中心表示，该风暴可能在稍后正式登陆时掠过哈利斯科州。
To the south, Hurricane Simon, with winds of 150 miles per hour that make it a Category 4 storm on the five-step Saffir-Simpson scale, was raking the coast of Mexico’s states of Jalisco and Colima with some of its strongest winds, the US hurricane center said. The storm may clip Jalisco later, when it makes an official landfall.
Pydynowski表示，该风暴也可能继续沿海岸平行移动，直至本周晚些时候才登陆。
Pydynowski said the storm may also continue to move parallel to the coast and not make landfall until later in the week.
根据墨西哥天气服务的预报，哈利斯科州将出现强降雨，海浪可能达到近20英尺（6米），冲击海岸线。
Heavy rain is forecast across Jalisco and waves up to nearly 20 feet (6 meters) may lash the coastline, according to Mexico’s weather service.
美国飓风中心的资深飓风专家埃里克·布莱克在展望中写道：“墨西哥西中部海岸部分地区可能遭遇灾难性风力和危及生命的风暴潮影响。” “西蒙带来的强降雨将影响墨西哥西南部部分地区，持续到本周末。”
“Catastrophic wind and life-threatening storm surge impacts are likely along a portion of the west-central coast of Mexico,” Eric Blake, a senior hurricane specialist at the US center, wrote in his outlook. “Heavy rainfall associated with Simon will impact portions of southwestern Mexico through this weekend.”
