A significant spring snowstorm has impacted Colorado and Wyoming, resulting in substantial snowfall, widespread power outages, and the suspension of educational and commercial activities.

一場強大的春季暴風雪影響了科羅拉多州和懷俄明州，導致大量降雪、大範圍停電，以及教育和商業活動的中斷。

The meteorological event commenced on May 5, 2026, characterized by the deposition of heavy, wet snow across the Front Range and high-elevation corridors. Precipitation totals exhibited significant variance based on altitude; while the Denver metropolitan area recorded between 4 and 10 inches—marking the most substantial May snowfall since 2003—alpine regions such as Estes Park reported accumulations as high as 27 inches. In Wyoming, Cheyenne recorded 8.9 inches, its most significant single-storm accumulation since March 2021. These conditions necessitated the temporary closure of Interstate 80 between Laramie and Cheyenne and created hazardous transit conditions on major arteries, including the Eisenhower Tunnel and Berthoud Pass.

此次氣象事件始於 2026 年 5 月 5 日，其特徵為前山地帶（Front Range）及高海拔走廊出現大量濕雪。降水總量隨海拔高度呈現顯著差異；丹佛都會區記錄到 4 至 10 英吋，為 2003 年以來最顯著的 5 月降雪量，而如 Estes Park 等高山地區的積雪則高達 27 英吋。在懷俄明州，夏延記錄到 8.9 英吋，為 2021 年 3 月以來單次風暴的最大積雪量。這些情況導致拉雷米與夏延之間的 80 號州際公路暫時關閉，並使包括艾森豪主義隧道（Eisenhower Tunnel）及 Berthoud Pass 在內的主要幹道交通狀況極其危險。

Institutional responses were extensive. Numerous educational entities, including Denver Public Schools and several other regional districts, mandated closures for May 6. The utility sector experienced significant strain, as the weight of the wet snow caused structural failure in arboreal limbs and power lines. Xcel Energy reported approximately 58,000 customers without power, while the Poudre Valley Rural Electric Association noted nearly 1,000 additional outages. Municipalities including Denver, Boulder, Arvada, and Broomfield implemented specific debris-management protocols to facilitate the removal of downed vegetation.

機構應對措施規模廣泛。包括丹佛公立學校在內的多個教育實體及其他區域學區，均要求 5 月 6 日停課。公用事業部門承受了巨大壓力，因濕雪的重量導致樹枝和電線發生結構性損壞。Xcel Energy 報告約有 58,000 名客戶停電，而 Poudre Valley Rural Electric Association 則記錄了近 1,000 宗額外停電。丹佛、波德、阿爾瓦達及布魯姆菲爾德等市實施了特定的碎片管理協定，以利於清除倒塌的植被。

From a climatological perspective, the event occurred against a backdrop of a prolonged snow drought, with Colorado's snowpack remaining at or below record lows since 1987. While the National Drought Mitigation Center indicated that the precipitation marginally improved topsoil moisture, it was determined that the event would not substantively alter the bleak long-term water outlook. Furthermore, the National Weather Service issued freeze warnings for multiple states, including Texas and New Mexico, citing potential risks to agricultural yields and exterior plumbing systems. A rapid thermal transition is anticipated, with temperatures projected to return to above-average levels by the weekend.

從氣候學角度來看，此次事件發生在長期積雪乾旱的背景下，科羅拉多州的積雪量自 1987 年以來一直處於或低於歷史低點。雖然國家乾旱緩解中心指出此次降水略微改善了表層土壤水分，但判定此次事件不會實質改變長期水資源短缺的慘淡前景。此外，國家氣象局向包括德克薩斯州和新墨西哥州在內的多個州發布結冰警告，指出對農作物產量及室外管道系統存在潛在風險。預計氣溫將快速回升，預計到週末將恢復至高於平均水平。

The storm has largely subsided, leaving behind significant debris and infrastructure damage, though temperatures are expected to rise sharply by the end of the week.

風暴已基本消退，雖然留下了大量碎片及基礎設施損壞，但預計本週末氣溫將大幅上升。
