圣克拉丽塔突发 Bike Fire：一小时烧过200英亩，四个区域强制疏散
洛杉矶县圣克拉丽塔市周日（10月11日）下午突发灌木火灾，火势在一小时内从5英亩迅速扩大到200英亩，加州林业和消防局（CAL FIRE）报告火势蔓延速度极快、火行为不稳定，多个社区已发布强制疏散令。
据洛杉矶县消防局通报，这场被命名为"Bike Fire"的火灾于当天下午约1点在 Cambria Estates Lane 与 Ravenhill Road 交界处被发现，地点靠近 Golden Valley、Sand Canyon 与 Placerita Canyon 一带。起火后火势迅速扩大：下午2点01分约75英亩，2点15分已超过115英亩并出现"不稳定的火行为"，到2点36分已达200英亩，仍在快速蔓延。
CAL FIRE 于下午2点34分扩大了疏散令。据官方火情页，强制疏散令覆盖 SCL-SULTUS、NADEU-A、SCL-SANDSOUTH-B 三个区域；据《纽约邮报》报道，疏散令在下午2点48分进一步扩大，新增 SCL-MACMILLAN 区。另有六个区域发布疏散警告，包括 SCL-NADEU-B、SCL-CRYSTALSPRINGS、SCL-WOODLAND、SCL-SANDSOUTH-A、SCL-FAIROAKSRANCH 和 LAC-E119-A。Nadeu、Sandsouth、Woodland、MacMillan 和 Crystal Springs 一带的居民被告知做好撤离准备，建筑物受到威胁。
两架空中消防机和两架一型直升机已被调动参与灭火。火灾起因目前不明，正在调查中。
值得注意的是，南加州本周正经历不稳定天气：前热带气旋 Rachel 带来的水汽造成降雨、阵风和沿海洪水。国家气象局警告山区和羚羊谷可能出现强阵风，沿海洪水担忧将持续到周二。
这是圣克拉丽塔地区一周内的第三场野火。10月3日在安吉利斯国家森林 Bouquet Canyon Road 附近发生的 Bouquet Fire 已烧1048英亩，截至周日控制率达83%；10月8日在 Gorman 以南约2英里处发生的 Danny Fire 为150英亩，控制率96%，火势已停止蔓延。

Bike Fire Erupts in Santa Clarita: 200 Acres in an Hour, Mandatory Evacuations in Four Zones
A brush fire erupted in Santa Clarita, Los Angeles County, on Sunday afternoon (Oct. 11), exploding from 5 acres to 200 acres within an hour. CAL FIRE reported a rapid rate of spread with erratic fire behavior, and mandatory evacuation orders have been issued for multiple neighborhoods.
According to the Los Angeles County Fire Department, the fire — dubbed the "Bike Fire" — was reported around 1 p.m. near Cambria Estates Lane and Ravenhill Road, close to Golden Valley and the Sand Canyon/Placerita Canyon area. It grew fast: about 75 acres by 2:01 p.m., over 115 acres with "erratic fire behavior" by 2:15 p.m., and 200 acres by 2:36 p.m., still burning at a rapid rate.
CAL FIRE expanded evacuation orders at 2:34 p.m. Mandatory orders cover zones SCL-SULTUS, NADEU-A and SCL-SANDSOUTH-B, according to the official incident page; the New York Post reported the orders were further expanded at 2:48 p.m. to add SCL-MACMILLAN. Evacuation warnings are in effect for six more zones: SCL-NADEU-B, SCL-CRYSTALSPRINGS, SCL-WOODLAND, SCL-SANDSOUTH-A, SCL-FAIROAKSRANCH and LAC-E119-A. Residents in Nadeu, Sandsouth, Woodland, MacMillan and Crystal Springs were told to prepare to leave as structures were threatened.
Two air tankers and two type 1 helicopters were mobilized to assist firefighting efforts. The cause of the fire remains unknown and is under investigation.
Notably, Southern California is grappling with turbulent weather this week: moisture from former Tropical Cyclone Rachel has brought rain, gusty winds and coastal flooding. The National Weather Service warned of potentially powerful wind gusts in mountain areas and the Antelope Valley, with coastal flooding concerns expected to persist into Tuesday.
This is the third wildfire in the Santa Clarita area in a week. The Bouquet Fire, reported Oct. 3 near Bouquet Canyon Road in the Angeles National Forest, has burned 1,048 acres and was 83% contained as of Sunday. The Danny Fire, reported Oct. 8 about two miles south of Gorman, was held at 150 acres and 96% contained.
