Severe heat waves and high fire risks are currently affecting the Northeastern, Southwestern, and Western United States. As a result, many public events have been changed or cancelled, and efforts to control wildfires have increased.

目前美國東北部、西南部與西部正受到嚴重熱浪與高山火風險影響。因此，許多公共活動已更改或取消，控制山火的努力也隨之增加。

In the Northeastern United States, temperatures have risen above 100 degrees Fahrenheit, which has forced many cities to cancel or reschedule 250th-anniversary celebrations. Local governments in Delaware, New Jersey, New York, and Pennsylvania have stopped parades and fireworks to protect public health. However, some organizers, such as those for the Great American State Fair in Washington, D.C., have decided to keep their events open by using cooling systems and increasing medical staff to keep visitors safe.

在美國東北部，氣溫已升至華氏100度以上，導致許多城市不得不取消或重新安排250週年慶祝活動。德拉瓦州、紐澤西州、紐約州與賓夕法尼亞州的地方政府已停止遊行與煙火表演，以保護公眾健康。然而，部分主辦單位，例如華盛頓特區的「偉大美國州博覽會」，決定透過使用冷卻系統及增加醫療人員來確保訪客安全，因此決定維持活動開放。

Meanwhile, the Southwest is seeing a shift in weather, with temperatures expected to rise above 110 degrees and humidity to increase next week. In Phoenix, the city government has introduced strict fireworks rules and fire restrictions to prevent fires near mountains and parks. Similarly, in Flagstaff, a drone show has replaced traditional fireworks due to high fire risks. Although the remains of Tropical Storm Douglas may bring some clouds, the region remains dangerously dry.

同時，西南部正經歷天氣轉變，預計下週氣溫將升至110度以上，且濕度將增加。在鳳凰城，市政府引入了嚴格的煙火規定與防火限制，以防止山脈與公園附近發生火災。同樣地，在弗拉格斯塔夫，由於山火風險高，無人機表演取代了傳統煙火。雖然熱帶風暴「道格拉斯」的殘餘部分可能會帶來一些雲層，但該地區依然處於危險的乾燥狀態。

Regarding wildfires, the Pocket Fire in Arizona has grown to about 20,680 acres and is only 21% contained. Fire officials emphasized that while the fire is moving toward containment lines, it is still causing poor air quality in Flagstaff and Sedona. Additionally, Shasta County in California has reported four vegetation fires since June 30. While two of these fires are 85% contained, the Bolla Fire is still being investigated by state forestry officials.

關於山火，亞利桑那州的Pocket Fire已擴大至約20,680英畝，且僅21%得到控制。消防官員強調，雖然火勢正向控制線移動，但仍導致弗拉格斯塔夫與塞多納的空氣品質不佳。此外，加州夏斯塔郡自6月30日起報告了四起植被火災。雖然其中兩起火災已控制85%，但Bolla Fire目前仍由州林務官員調查中。

The current situation is defined by extreme heat and dangerous fire conditions. Consequently, local authorities must adjust public safety rules and continue deploying resources to stop wildfires.

目前的狀況是以極端高溫與危險的火災條件為主。因此，地方當局必須調整公共安全規定，並持續部署資源以阻止山火。
