A major heatwave is currently developing across the central and eastern United States and Canada, which could affect the scheduling and safety of World Cup matches.

目前美國與加拿大中東部正形成一場強烈熱浪，這可能會影響世界盃賽事的排程與安全性。

The National Weather Service (NWS) has reported that a serious heat event is intensifying, with temperatures expected to rise above 32°C across large areas of the U.S. and Canada. In Ontario and Quebec, temperatures may be up to 10°C higher than usual. Because of the combination of high heat and humidity, the heat index could reach 46°C in the southern Plains. Furthermore, 'tropical nights' are expected, meaning temperatures will stay above 20°C even at night.

美國國家氣象局 (NWS) 報告指出，一場嚴重的熱浪事件正在加劇，預計美國與加拿大大片地區的氣溫將升至 32°C 以上。在安大略省與魁北克省，氣溫可能比平常高出 10°C。由於高溫與高濕度的共同影響，南部平原的體感溫度可能達到 46°C。此外，預計將出現「熱夜」，意即夜間氣溫仍將維持在 20°C 以上。

Officials are concerned about how this heat will affect the athletes. They use the Wet Bulb Global Temperature (WBGT) to measure heat stress, and Fifpro has stated that conditions are unsafe for competition if the WBGT reaches 28°C. It is predicted that matches in Miami and Kansas City may hit this limit, with temperatures feeling like 40°C. While stadiums in Houston, Dallas, and Atlanta have air conditioning to reduce risks, the travel of fans remains a concern.

官方擔心這些高溫將如何影響運動員。他們使用「濕球黑球溫度」(WBGT) 來衡量熱壓力，而 Fifpro 則表示，若 WBGT 達到 28°C，比賽環境將是不安全的。預計邁阿密與堪薩斯城的賽事可能會達到此上限，體感溫度將接近 40°C。雖然休士頓、達拉斯與亞特蘭大的體育場設有空調以降低風險，但球迷的交通往來仍令人擔憂。

To manage these risks, FIFA has introduced hydration breaks and is following its emergency care manual, which requires specific actions when WBGT reaches 32°C. Additionally, thunderstorms pose another risk to the games. While storms are currently in the Northern Plains, they are expected to move toward host cities. There is a high chance of storms in Miami and a small risk in Atlanta. According to the rules, play must be stopped immediately if lightning is detected within eight miles of the stadium.

為了管理這些風險，FIFA 引入了水分補充休息時間，並遵循其緊急護理手冊，該手冊要求在 WBGT 達到 32°C 時採取特定行動。此外，雷陣雨對比賽構成了另一項風險。雖然風暴目前位於北部平原，但預計將向主辦城市移動。邁阿密發生風暴的可能性很高，亞特蘭大則有較小風險。根據規定，若在體育場方圓八英里內偵測到閃電，比賽必須立即停止。

Extreme heat and potential thunderstorms are currently threatening the smooth progress of the tournament as it moves into the Round of 16.

在賽事進入 16 強賽之際，極端高溫與潛在的雷陣雨目前正威脅著錦標賽的順利進行。
