全国紧急警报系统测试11月17日举行：美东时间下午2时20分广播电视将中断约1分钟 公众无需采取行动
联邦紧急事务管理局（Federal Emergency Management Agency，FEMA）与联邦通信委员会（Federal Communications Commission，FCC）将于11月17日（周二）美东时间约14时20分（美西时间约11时20分）举行紧急警报系统（Emergency Alert System，EAS）全国测试，届时全美广播、电视、有线与卫星节目将中断约1分钟播出测试信息，公众无需采取任何行动；两家机构提前公布日期，是为了让公众预先知道测试当天会看到什么。
联邦紧急事务管理局在公告中说，紧急警报系统是美国的全国公共警报系统，由数以千计的广播电台、电视台、有线系统、卫星广播电视服务商与有线视频服务商组成；在国家紧急状态下，总统可通过这一系统向全国公众讲话或发布救命信息。法律要求联邦紧急事务管理局至少每三年对全国公共警报与预警系统进行一次测试，以便在系统真正用于紧急情况之前发现技术或运行问题。据广播行业媒体 Radio Ink 报道，这将是自2023年10月以来首次举行全国紧急警报系统测试。
测试当天，美东时间约14时20分，全国广播电视机构、有线系统、卫星广播电视服务商与有线视频服务商将中断正常节目，转播一条测试信息，内容为：「这是由联邦紧急事务管理局发布的紧急警报系统全国测试，覆盖全美，美东时间2时20分至2时50分。这只是一次测试，公众无需采取任何行动。」联邦紧急事务管理局说，测试信息将持续约1分钟，测试结束后节目恢复正常；测试信息带标准警报音，以照顾失聪或听障人士，各台可根据做法与受众需要以英语、西班牙语或双语播出。联邦通信委员会说，如测试因故改期，备用日期为12月3日。
联邦紧急事务管理局与联邦通信委员会正与参与的通信服务商，以及联邦、州、部落与领地机构协调筹备这次测试。两家机构表示，提前公布测试日期十分重要，因为公众需要事先了解测试当天的情形，以免把测试信息误认为真实警报；有关紧急警报系统的更多信息可在联邦紧急事务管理局官网查询。
Nationwide Emergency Alert System Test Set for November 17: Broadcasts Interrupt at About 2:20 p.m. ET for One Minute, No Action Required
The Federal Emergency Management Agency (FEMA), in coordination with the Federal Communications Commission (FCC), will conduct a nationwide test of the Emergency Alert System (EAS) on Tuesday, November 17, 2026, at approximately 2:20 p.m. Eastern Time (about 11:20 a.m. Pacific Time). Radio and television broadcasters, cable systems, satellite radio and television providers, and wireline video providers nationwide will interrupt normal programming for about one minute to relay a test message, and no action is required by the public. The two agencies are sharing the test date in advance so the public understands what to expect on the day of the test.
FEMA said the Emergency Alert System is a national public warning system made up of thousands of radio, television, cable, satellite and wireline video providers. Through the system, the President can address the American people or share life-saving information with the public during a national emergency. FEMA is required by law to conduct a nationwide test of the public alert and warning system at least once every three years, so the agency can identify technical or operational issues before the system is needed during an actual emergency. According to broadcast trade outlet Radio Ink, this will be the first nationwide EAS test since October 2023.
At about 2:20 p.m. ET on November 17, participating providers will relay a test message stating: "This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency, covering the United States from 2:20 to 2:50 hours ET. This is only a test. No action is required by the public." FEMA said the test will last approximately one minute and normal programming will resume when it concludes. The message will include standard EAS alert tones to support accessibility for individuals who are deaf or hard of hearing, and broadcasters may air it in English, Spanish or both, depending on station practices and audience needs. The FCC said that if conditions require the test to be rescheduled, the backup date is December 3, 2026.
FEMA and the FCC are coordinating with participating communications providers and with federal, state, tribal and territorial agencies to prepare for and conduct the test. More information about the Emergency Alert System is available on FEMA's website.
