A series of powerful thunderstorms and tornadoes have hit the Midwest and East Coast, causing building damage, power outages, and one confirmed death.

一系列強烈的雷暴與龍捲風襲擊了中西部與東海岸，導致建築物損毀、停電，並確認一名人員死亡。

The worst weather occurred in the Midwest, where cold air from Canada met humid air from the south, which caused a major storm system. On June 11 and 12, 2026, the National Weather Service recorded more than twelve tornadoes across Illinois, Indiana, and Wisconsin. In Streator, Illinois, officials declared a state of emergency after several homes were destroyed. The Storm Prediction Center had previously warned that the Chicago area faced a Level 4 risk, which usually happens only once every two years. Unfortunately, a 54-year-old man died in Des Moines, Iowa, after being hit by a falling tree.

最惡劣的天氣發生在中西部，來自加拿大的冷空氣與來自南方的潮濕空氣相遇，導致形成一個大型風暴系統。在 2026 年 6 月 11 日和 12 日，國家氣象局在伊利諾州、印第安納州和威斯康辛州記錄到超過 12 場龍捲風。在伊利諾州的斯特雷特，由於數棟房屋被毀，官員宣布進入緊急狀態。風暴預測中心先前曾警告芝加哥地區面臨 4 級風險，這種情況通常每兩年才發生一次。不幸的是，愛荷華州德梅因市一名 54 歲男子被倒塌的樹木擊中而死亡。

These storms caused serious problems for infrastructure and travel. Power companies reported that hundreds of thousands of customers lost electricity across several states. Additionally, flights at O'Hare, Midway, and JFK airports were delayed or canceled due to ground stops and evacuations, affecting over 1,000 flights. Even sports were impacted, as a Major League Baseball game in Chicago was postponed because of the heavy rain.

這些風暴對基礎設施和交通造成了嚴重問題。電力公司報告稱，數個州的數十萬名客戶失去了電力供應。此外，由於地面停飛和撤離，歐海爾、中途島及 JFK 機場的航班被延遲或取消，影響超過 1,000 個航班。甚至體育賽事也受到影響，芝加哥的一場大聯盟棒球賽因大雨而延期。

At the same time, the East Coast experienced extreme heat. New Jersey and New York recorded record-high temperatures, with the heat index reaching 100 degrees Fahrenheit. Consequently, cities like Philadelphia opened cooling centers and started emergency health protocols to protect citizens. These heatwaves were followed by severe thunderstorms that caused local power failures and wind damage. US officials emphasized that these extreme patterns were caused by the El Niño phenomenon and warned that the weather might become even more unstable in the autumn.

與此同時，東海岸經歷了極端高溫。紐澤西州和紐約州記錄到創紀錄的高溫，體感溫度達到華氏 100 度。因此，像費城這樣的城市開設了避暑中心，並啟動緊急醫療方案以保護市民。隨後，這些熱浪引發了嚴重的雷暴，導致局部停電和風災。美國官員強調，這些極端模式是由聖嬰現象引起的，並警告秋季的天氣可能會變得更加不穩定。

The United States remains under several weather warnings as recovery work begins in the Midwest and heat risks continue along the Atlantic coast.

隨著中西部開始進行復原工作，且大西洋沿岸的高溫風險持續，美國仍處於多項天氣警告之中。
