洛杉矶县厄尔尼诺防备指南本周更新：11月14日 Lakewood 办免费防灾讲座，野火烧毁区冬季风暴易发泥石流
位于加州洛杉矶县的县应急管理办公室将于11月14日（周六）上午10时30分至11时30分在 Lakewood 的 Angelo M. Iacoboni 图书馆（4990 Clark Ave）办一场免费防灾讲座，这是洛杉矶县本周更新的厄尔尼诺防备指南中公布的新活动：讲座讲解南加州风暴季的备灾步骤、紧急警报与社区风险，并说明怎样制定家庭应急计划；活动面向成人、名额有限，须提前报名。
指南本周重点提醒，冬季风暴期间陡峭山坡地带、尤其是近期野火烧毁的山坡，容易发生泥石流与泥沙碎屑流。大火烧掉固定土壤的植被，高温还会改变土壤性质、妨碍雨水下渗，暴雨时雨水、泥沙与枝干碎屑可能顺坡冲下，危及生命与房屋。县府建议居民摸清自家房屋的风险因素、清理排水通道，并用沙袋导引径流、保护建筑。
本周提示是「掉头，不要涉水」：绝不要驾车穿过洪水，看不见路面时就掉头改道。居民备灾指南与降雨资源可在县府防灾页面查阅。
县消防局的免费社区沙袋发放仍在继续，发放期至11月28日。

LA County Updates El Niño Guide: Free Preparedness Event in Lakewood November 14, Mudslide Warning for Burn Areas
The Los Angeles County Office of Emergency Management will hold a free storm preparedness event on Saturday, November 14, from 10:30 to 11:30 a.m. at the Angelo M. Iacoboni Library, 4990 Clark Ave in Lakewood, in Los Angeles County, California. Announced in this week's update to the county's El Niño preparedness guide, the program covers the essential steps to prepare a home and family for heavy rain and potential flooding, emergency alerts and warnings, community hazards, and how to build an effective emergency plan. It is for adults, attendance is limited, and advance registration is required.
The guide's warning this week is that winter storms bring the danger of mud and debris flows in steep hillside areas, especially on slopes affected by recent wildfires. Fire destroys the vegetation that holds soil in place, and intense heat can change the soil itself and prevent water absorption, so rain, mud, branches and other debris can roar down hillsides during a storm. The county advises residents to know their property's risk factors, clear drainage paths, and use sandbags to direct runoff and protect structures.
The tip of the week is Turn Around, Don't Drown: never drive through floodwater, and if the road cannot be seen, turn around and find another route. A homeowners' guide and rain resources are available on the county's preparedness pages.
The County Fire Department's free community sandbag distributions are continuing, running through November 28.
