美国各地严重天气威胁使数百万美国人警惕即将到来的暴风雪天气、潜在龙卷风及破纪录高温。
据预报员称，超过1150万人处于暴风雪预警下，另有430万人处于冬季风暴预警下，约2060万人处于极端高温观察状态。
预计周一，一场风暴系统将在北部平原和五大湖上游带来危及生命的出行条件，美国东部一半地区可能出现破坏性大风和龙卷风。
西部部分地区预计本周大部分时间将出现异常提前的热浪。
暴风雪袭击北部平原和五大湖上游
周日，一场快速增强的风暴正从南达科他州东部经威斯康星州延伸至密歇根州上半岛，带来暴风雪天气。
美国国家气象局报告称，明尼苏达州和威斯康星州部分地区周日降雪超过一英尺，明尼阿波利斯地区在暴风雪预警下可能再降几英寸雪。
明尼苏达州、密歇根州和威斯康星州已发布危险路况警告，交通官员警告称，周日能见度低且道路被雪覆盖，路况将进一步恶化。
追踪航班中断的FlightAware网站显示，明尼阿波利斯-圣保罗国际机场周日有超过600架次进出港航班被取消，底特律机场也有数十架次航班取消。
明尼苏达州南部已发布禁行通知，州长蒂姆·瓦尔兹已授权明尼苏达国民警卫队支持应急行动，CBS明尼苏达频道报道。
威斯康星州清雪车司机艾伦·哈斯称这是他多年来见过的最严重风暴。周日在马什菲尔德镇，他正在堆积高达卡车的雪堆。
“在城外高速公路上你什么都看不见，”他说。
暴风雪天气可能持续至周一，风暴过后将出现额外的大湖效应降雪。
严重天气威胁向东扩展
引发暴风雪的同一风暴系统，正通过强大冷锋在中西部和南部引发强烈风暴。
预计周日一条发展中的飑线将横扫中西部和中南部部分地区，夜间向东移动。预报员警告，从五大湖下游到俄亥俄和田纳西河谷的严重天气风险增强。

周一威胁将加剧，中大西洋部分地区将面临中度严重天气风险。预报员称，风暴向东海岸推进时可能产生龙卷风、破坏性阵风、冰雹和山洪。
美国国家气象局表示，南卡罗来纳州至马里兰州一带周一下午最可能遭遇特别强风，包括北卡罗来纳州罗利、弗吉尼亚州里士满和首都华盛顿。风险向北延伸至纽约部分地区，向南至佛罗里达州北部，尽管强度较低但仍有增加。

西部提前出现季节性热浪
当美国中部和东部为风暴做准备时，美国西部正受加强的高压脊驱动，迎来异常提前的热浪。
预报员称，从周一开始至本周大部分时间，南加州、西南沙漠和大盆地可能出现创纪录高温。沙漠地区气温可能攀升至90至100华氏度，而加州大部分地区和西部内陆可能达到70至80华氏度。
温暖、干燥且多风的天气模式还将增加西部和高平原部分地区的野火风险。
夏威夷毛伊岛滑坡、救援与房屋倒塌
夏威夷多处农田和房屋被淹，道路关闭，避难所开放。追踪全国停电情况的PowerOutage.us网站报告，截至周日早些时候，夏威夷已有超过5万名电力用户断电。
夏威夷应急管理局称，毛伊岛、莫洛凯岛和大岛等地近几日暴雨成灾，夜间降雨量达每小时1至2英寸。
毛伊县县长理查德·比森周六晚在社交媒体帖子中称，毛伊岛部分地区过去24小时降雨量达20英寸。
“全县范围内我们正经历洪水、山体滑坡、塌陷、碎片和倒下的电线，”他说。市长用夏威夷语表示感谢，补充道”mahalo（谢谢）大家继续互相照应。”

Major weather threats bring blizzard conditions to U.S. northern tier, early heatwave to the West
March 15, 2026 / 3:26 PM EDT / CBS/AP
Severe weather threats across the United States have millions of Americans on alert for blizzard conditions, potential tornadoes and record-breaking high temperatures in the coming days.
More than 11.5 million people are under blizzard warnings, another 4.3 million are under winter storm warnings, and about 20.6 million are under an extreme heat watch, according to forecasters.
A storm sweeping system is expected to bring life-threatening travel conditions in the Northern Plains and Upper Great Lakes, the potential for damaging winds and tornadoes across the eastern half of the country on Monday.
Across parts of the West, an unusually early heat wave is expected for much of the week.
Blizzard slams Northern Plains, Upper Great Lakes
A rapidly intensifying storm is producing blizzard conditions from eastern South Dakota through Wisconsin into Michigan’s Upper Peninsula on Sunday.
More than a foot of snow fell in some portions of Minnesota and Wisconsin on Sunday, according to National Weather Service reports, with another several inches likely to fall in the Minneapolis area amid blizzard warnings by the weather service.
Warnings of hazardous road conditions were issued across Minnesota, Michigan and Wisconsin, where transportation officials warned of worsening conditions Sunday with low visibility and snow-covered roadways.
More than 600 flights flying out of and into the Minneapolis-Saint Paul International Airport were canceled Sunday, according to FlightAware, a website that tracks flight disruptions. Dozens more through Detroit were also scrapped.
State officials have issued a no-travel advisory in southern Minnesota, and Gov. Tim Walz has authorized the Minnesota National Guard to support emergency operations, CBS Minnesota reported.
Wisconsin snowplow driver Aaron Haas said it was one of the worst storms he had seen in years. On Sunday, he was stacking piles of snow as high as his truck in the town of Marshfield.
“You can’t see anything when you’re on the highways outside of the city,” he said.
Blizzard conditions are likely to stretch into Monday with additional lake-effect snow behind the storm.
Severe weather threat expanding east
The same storm fueling the blizzard is also triggering severe storms across the Midwest and South along a powerful cold front.
A developing squall line is expected to sweep across parts of the Midwest and Mid-South on Sunday, moving east overnight. Forecasters warn of an enhanced risk of severe weather from the Lower Great Lakes through the Ohio and Tennessee valleys.

The threat is expected to intensify Monday, when a moderate risk of severe weather stretches across parts of the Mid-Atlantic. Storms could produce tornadoes, damaging wind gusts, hail and flash flooding as they push toward the East Coast, according to forecasters.
A stretch from parts of South Carolina to Maryland appeared most likely to experience particularly damaging winds Monday afternoon, the weather service said. That could include Raleigh, North Carolina; Richmond, Virginia and the nation’s capital. The weather service said an increased — albeit much lower — risk stretched north to a portion of New York and south to northern Florida.

Early-season heat building in the West
While the central and eastern U.S. brace for storms, the western U.S. is heading into an unusually early heat wave driven by a strengthening ridge of high pressure.
Beginning Monday and continuing through much of the week, record-high temperatures are possible across Southern California, the Desert Southwest and the Great Basin, forecasters said. Desert areas could see temperatures climbing into the 90s and 100s, while much of California and the interior West may experience highs in the 70s and 80s.
The warm, dry, and windy pattern is also expected to increase wildfire danger across parts of the West and High Plains.
Landslides, rescues, and collapsed homes on Maui
Acres of farmland and homes have been flooded in Hawaii. Roads have been closed, and shelters opened. PowerOutage.us, which tracks outages nationwide, reported over 50,000 electric customers in Hawaii without power as of early Sunday.
Flash flooding has been a major problem in recent days in places like Maui, Molokai and the Big Island, where rain had been falling from 1 to 2 inches an hour overnight, according to the Hawaii Emergency Management Agency.

Maui County Mayor Richard Bissen said in a social media post late Saturday that some areas of Maui had received 20 inches of rain in the previous 24 hours.
“We’re seeing flooding, landslides, sinkholes, debris and downed power lines across the county,” he said. Expressing gratitude in the Hawaiian language, the mayor added “mahalo for continuing to look out for one another.”
