A series of major wildfires has affected Utah and Colorado during the early summer of 2026, made worse by difficult weather conditions.

2026年早夏，一系列重大山火影響了猶他州與科羅拉多州，且因惡劣的天氣條件而進一步惡化。

The current increase in wildfires is caused by a combination of weather factors, specifically a lack of winter snow and an unusual period of heat and dryness. The National Interagency Fire Center had already warned of a high risk for the Great Basin and Rocky Mountain regions. Consequently, by July 7, 2026, the total burned area reached 5,265 square miles, which is 46 percent higher than the average for the last ten years.

目前的山火增加是由多項天氣因素共同引起，特別是冬季降雪不足以及異常的高溫與乾燥期。國家跨 agency 火災中心先前已警告大盆地與落基山脈地區存在高風險。因此，截至 2026 年 7 月 7 日，總燒毀面積達到 5,265 平方英里，比過去十年的平均值高出 46%。

In Utah, the Cottonwood fire has caused significant damage, affecting about 150 square miles of rough terrain. This fire destroyed up to 150 buildings, including important facilities at the Eagle Point Ski Resort. However, the Tushar Campground was saved, which suggests that previous forest management, such as clearing brush, may have reduced the fire's impact. Experts tracked this event using NASA's Fire Events Data Suite (FEDS), which used thermal sensors to monitor the fire's rapid growth on June 23 and 26.

在猶他州，Cottonwood 山火造成了重大損害，影響約 150 平方英里的崎嶇地形。這場火毀掉了多達 150 棟建築，包括 Eagle Point 滑雪場的重要設施。然而，Tushar 營地得以倖存，這顯示先前的森林管理（如清理灌木）可能降低了山火的影響。專家利用 NASA 的火災事件數據套件 (FEDS) 追蹤此次事件，透過熱感測器監控 6 月 23 日和 26 日山火的快速增長。

At the same time, Colorado is dealing with the Aspen Acres fire, which was started by humans and has burned 96,031 acres. Although containment has reached 15 percent, the situation remains unstable. The National Weather Service (NWS) emphasized that while expected rain might slow the fire, it also creates new dangers. Specifically, areas already burned have water-repellent soil and fewer plants, which increases the risk of flash floods and mudslides. Other active fires in Colorado, such as the Ferris and Gold Mountain fires, make it even harder to distribute emergency resources.

與此同時，科羅拉多州正在處理由人為引起、已燒毀 96,031 英畝的 Aspen Acres 山火。儘管圍堵率已達到 15%，但情況仍然不穩定。國家氣象局 (NWS) 強調，雖然預期的降雨可能會減緩火勢，但也會帶來新危險。具體而言，已燒毀地區的土壤具有撥水性且植被較少，增加了山洪與泥石流的風險。科羅拉多州內其他活躍的山火，如 Ferris 和 Gold Mountain 山火，使得緊急資源的分配更加困難。

Wildfire activity remains extreme in the western U.S., and containment efforts continue despite unpredictable weather patterns.

美國西部的山火活動依然處於極端狀態，儘管天氣模式難以預測，圍堵工作仍在持續。
