Tropical Storm Arthur, the first named storm of the 2026 Atlantic hurricane season, became a post-tropical cyclone after hitting Texas. This change caused widespread flooding across the southeastern United States.

Arthur 熱帶風暴是 2026 年大西洋颶風季的第一個命名風暴，在擊中德克薩斯州後變成了後熱帶氣旋。這次轉變導致美國東南部 widespread 範圍內出現嚴重淹水。

The storm began as a group of thunderstorms over the Gulf Coast and developed into a tropical storm before weakening into a low-pressure area on Wednesday night. Although the strongest winds were only about 35 mph, the National Hurricane Center (NHC) emphasized that the main danger was heavy rainfall. Experts estimated that 5 to 10 inches of rain would fall, with some areas receiving up to 20 inches. This moisture moved east from Texas and Louisiana toward Georgia and the Florida Panhandle by Friday.

風暴最初始於墨西哥灣沿岸的一組雷陣雨，隨後發展為熱帶風暴，並在週三晚上弱化為低壓區。雖然最強風速僅約每小時 35 英里，但國家颶風中心（NHC）強調，主要危險在於強降雨。專家估計雨量將達 5 至 10 英吋，部分地區甚至高達 20 英吋。這些水氣於週五起從德克薩斯州和路易斯安那州向東移向喬治亞州和佛羅里達州狹長地帶（Panhandle）。

Local authorities responded by distributing sandbags and cleaning drainage systems in Louisiana and Mississippi. In Picayune, Mississippi, officials declared a state of emergency after seven inches of rain fell in just six hours. Consequently, infrastructure was heavily affected; nearly 40,000 residents in Louisiana lost power, especially in Jefferson and Terrebonne parishes. Furthermore, the Louisiana Department of Transportation had to close several roads due to fallen trees and deep flooding.

當地政府採取應對措施，在路易斯安那州和密西西比州分發沙包並清理排水系統。在密西西比州的 Picayune，官員在短短六小時內降下七英吋雨量後，宣布進入緊急狀態。因此，基礎設施受到嚴重影響；路易斯安那州近 4 萬名居民失去電力，特別是在 Jefferson 和 Terrebonne 教區。此外，路易斯安那州交通部因樹木倒塌和深水淹水而不得不關閉多條道路。

There were serious human and commercial impacts, including the death of a 15-year-old boy in a flooded pond in Montgomery County, Texas. On the other hand, a FIFA World Cup match in Houston continued as planned because the stadium has a roof. In the Florida Panhandle, the rain actually helped reduce a moderate drought in Bay County, although the National Weather Service kept flood watches in place until June 19.

此次事件造成嚴重的人員及商業影響，包括德克薩斯州 Montgomery 縣一名 15 歲少年在淹水的池塘中死亡。另一方面，由於休士頓的體育場設有屋頂，一場 FIFA 世界盃賽事按計劃照常進行。在佛羅里達州狹長地帶，這場雨實際上幫助緩解了 Bay 縣的中度乾旱，儘管國家氣象局將洪水監測維持至 6 月 19 日。

The remains of Arthur are expected to leave the southeastern United States and move into the Atlantic Ocean by Friday, leaving behind significant flood damage and local infrastructure problems.

Arthur 的殘餘部分預計將於週五離開美國東南部並移向大西洋，留下嚴重的淹水損害和當地基礎設施問題。
