周五下午约 1 点，干燥炎热的天气导致位于洛杉矶县东北部约 45 英里（72公里）处的高沙漠地区发生灌木火灾 [1]。火势在傍晚时已蔓延至约 2,700 英亩（1,092公顷），当局随即发布了疏散命令 [1]。受高温影响，该地区气温飙升至近 100 华氏度（38摄氏度）[1]。与此同时，美国大部分地区正遭遇由热穹顶引发的高温浪潮，进一步加剧了野火风险 [1]。皮尼奥山部分区域于周五晚间收到疏散警告 [1]。为应对灾情，美国红十字会在洛杉矶县 YMCA 开设了避难所供民众安置 [1]。
A rapidly spreading brush fire ignited around 1 p.m. on Friday afternoon in the high desert area approximately 45 miles northeast of downtown Los Angeles [1]. Dry and hot weather conditions contributed to the blaze's quick growth, with flames reaching an estimated size of about 2,700 acres by evening [1]. Authorities issued evacuation orders for residents in the remote region as the fire expanded [1].
The extreme heat exacerbated wildfire risks across much of the United States due to a high-pressure dome causing a wave of record-breaking temperatures [1]. In Los Angeles County specifically, temperatures soared near 100 degrees Fahrenheit (38 Celsius) at the site of the incident [1]. As night fell on Friday, evacuation warnings were also issued for parts of Mount Pinos located nearby [1]. To assist displaced residents, the American Red Cross opened a shelter at a YMCA in Los Angeles County [1].
