唐纳德·特朗普总统为美国建国250周年举办的庆祝活动将于周六达到高潮，届时国家广场将上演破纪录的烟花秀，但与此同时，华盛顿正遭遇酷暑天气，且特朗普将自己置于纪念活动核心的做法也引发了争议。
尽管一场危险的热浪可能会影响观众，特朗普仍宣布将在“致敬美国”活动中发表长篇讲话。
在周三的集会上，特朗普对任何有关高温会阻碍他发表讲话的担忧予以驳斥。“顺便说一句，7月4日当天气温将达到约107华氏度，我还是会到场，而且会发表一场非常长的演讲，以此证明我无所不能，”特朗普说道。
这场备受瞩目的讲话出台之际，特朗普为纪念建国250周年规划的另一项活动“伟大美国州博览会”正面临观众人数不多和后勤受挫的问题。与州博览会一样，“致敬美国”活动由“自由250”组织——一个由特朗普支持的非营利机构负责筹办，该机构的任务是举办一系列半世纪纪念活动，以契合总统的文化议程。8月还将举办一场街头“自由250大奖赛”，以及一场名为“爱国者运动会”的青少年体育赛事，总奖金达25万美元。
“自由250”已建议观众在东部时间下午5点场馆开放前一小时内抵达国家公园场地，以应对高温天气。活动将包含音乐表演和多架次的军用飞机飞越表演。
以下是需要了解的信息：
在这个周末假期到来前，一场热浪正席卷美国东海岸，由于民众纷纷躲进装有空调的住宅和商铺消暑，电网承受着巨大压力。华盛顿特区已启动极端高温预警，预警将持续至7月5日，预计周六将成为有记录以来华盛顿最热的独立日，当前预报气温为101华氏度。华盛顿有记录以来最热的独立日是1919年的100华氏度。
高温已经打乱了筹备工作。由于天气过热，美国国会警察限制了7月2日年度“国会山独立日音乐会”预演活动的到场人数，周五的安检入口开放时间也因天气原因延后。
“自由250”在场地各处设置了免费补水站和喷雾站，供与会者对抗高温。在接到高温预警后，该组织调整了物品携带限制，允许观众携带空的可重复使用非金属水瓶，在公园内的补水站补水。“自由250”的发言人雷切尔·赖斯纳告诉CNN，该组织将免费分发饮用水瓶。
与以往庆祝活动一样，观众不得携带背包、冷藏箱、折叠椅、无人机、枪支或喷雾类物品，但场内可购买食品和饮料，手持风扇可带入活动区域。今年的活动还实施了透明包政策，该组织称此举旨在加快安检速度。
尽管存在特朗普再次遇袭的隐忧，以及始终存在的独行枪手威胁，但多位参与策划活动的官员此前告诉CNN，华盛顿有能力保障这类大型活动的安全。
联邦机构还将协助保护美国各地的其他独立日庆祝活动，包括波士顿、加利福尼亚州、宾夕法尼亚州和纽约州的活动。
华盛顿特区的观众将通过安检金属探测门接受检查。负责此次独立日活动的特勤局将与联邦调查局、大都会警察局及其他联邦和地方警方协同，同时保障特朗普的空中表演以及在国家广场举办的“伟大美国州博览会”的安全。
由于华盛顿特区将实施大范围道路封闭，主办方鼓励观众乘坐公共交通工具出行。华盛顿特区市长穆丽尔·鲍泽宣布，华盛顿都会区交通局将在东部时间下午5点后免费开放，并运营至次日凌晨2点。
特勤局发言人汤姆·林奇告诉CNN，总统的出席是此次庆祝活动被列为国家特殊安全事件的原因之一。这一简称NSSE的 designation 通常用于可能成为犯罪分子或恐怖分子目标的大型活动。林奇表示，因此今年庆祝活动的安检级别将是近年来所有人记忆中独立日活动所未有的。
预计特朗普将在东部时间晚上9点45分登台讲话，烟花秀将于东部时间晚上10点30分开始，但他的演讲时长目前尚不明确。
特朗普将此次独立日活动宣传为一场“特朗普式”集会，并吹嘘自己在华盛顿庆祝活动中的核心地位，尽管民主党人批评他将这场建国250周年纪念活动变成了一场以他本人而非国家为中心的党派庆祝活动。
鲍泽最初宣布，年度大型烟花秀将推迟至东部时间晚上11点才开始，比去年的活动晚两小时，但如今烟花秀将在东部时间晚上10点30分开始，持续约40分钟。
此次烟花秀预计将创下新的吉尼斯世界纪录，成为规模最大的烟花表演。届时将从林肯纪念堂倒影池、波托马克河驳船和西波托马克公园的10个燃放点发射近85万枚烟花弹。目前的纪录是2016年菲律宾新年倒计时活动中的810904枚烟花。华盛顿的这场烟花秀规模预计将是纽约梅西百货独立日烟花秀的10倍左右，后者通常是美国规模最大的独立日庆祝活动。
CNN此前报道称，这场烟花秀的预估成本为85万美元。
烟花会产生烟雾污染，其污染程度有时可与野火媲美，且烟雾可在空气中停留数小时。在一些城市，空气质量通常要到次日中午左右才能恢复正常，而高温可能会延长这一恢复过程。
但在一些城市，甚至在烟花燃放之前，高温就已经造成了另一种空气污染——地面臭氧。地面臭氧由汽车尾气、高温和阳光相互作用形成，会刺激肺部，可能在夜间庆祝活动开始前就加剧空气质量问题。包括华盛顿在内的高温地区预计白天将出现至少中度的地面臭氧污染。
当被问及美国环境保护署是否会跟踪烟花秀造成的空气污染影响时，EPA新闻发言人布里吉特·赫希告诉CNN：“烟花非常棒，我们希望所有人在庆祝美国建国250周年之际，都能在首都及其周边地区欣赏到精彩的烟花表演。”
对于在家观看的观众，各大电视台将播出特别报道。CNN将从东部时间中午12点开始进行现场直播。
烟花将从林肯纪念堂倒影池发射——自该池底部的蓝色涂层开始剥落以来，这里一直饱受争议和关注。特朗普下令斥资1400万美元翻新该水池后，水池被刷成蓝色并重新注水。
在这项耗资不菲的面子工程实施数周后，特朗普声称是破坏者损坏了饱受藻类困扰的倒影池，并誓言将其修复。周四，华盛顿大陪审团起诉了一名前奥运皮划艇运动员，指控其损坏林肯纪念堂前的倒影池。华盛顿特区联邦检察官让琳·皮尔罗周四表示，美国检察官办公室正在调查“大约六起”其他相关案件。

What we know about Trump’s July Fourth fireworks event

President Donald Trump’s celebration for America’s 250th anniversary will culminate Saturday with a record-breaking fireworks show on the National Mall amid scorching temperatures and controversy over his efforts to put himself at the center of the commemoration.
Trump has teased lengthy remarks as part of the “Salute to America” event despite a dangerous heat wave’s potential to impact audiences.
During a Wednesday rally, the president dismissed any concerns about the heat stopping him from giving remarks. “By the way, on July Fourth, it’s going to be approximately 107 degrees out, and I’m going to go, and I’m going to make a really long speech just to show that I can do anything,” Trump said.
The high-profile remarks come as another piece of Trump’s 250th programming, the “Great American State Fair,” contends with modest crowds and logistical setbacks. Along with the fair, “Salute to America” is organized by Freedom 250 – a Trump-backed nonprofit tasked with putting on a series of semiquincentennial events that cater to the president’s cultural agenda. August will include a street “Freedom 250 Grand Prix” and a youth athletic contest branded as the “Patriot Games” with a grand prize of $250,000.
Freedom 250 has advised guests to arrive at the national park grounds no more than one hour before doors open at 5 p.m. ET to account for the heat. The event will feature performances from musical performances and a slew of military flyovers.
Here’s what to know:
Ahead of the holiday weekend, a heat wave is tightening its grip on the East Coast and straining the electric grid as people seek to cool off in their air-conditioned homes and businesses. Washington, DC, has activated an extreme heat alert through July 5, as Saturday is expected to mark the hottest July Fourth that DC has ever recorded, boasting a current forecast of 101 degrees. The hottest July Fourth in the nation’s capital on record was 100 degrees in 1919.
The heat has throttled preparations. The US Capitol Police restricted attendance for a July 2 rehearsal event ahead of the annual “A Capitol Fourth Concert,” due to the excessive heat and gate openings were shifted later to account for weather on Friday.
Freedom 250 is offering complimentary water refills and misting stations scattered across the site as attendees battle high temps. Following a heat advisory, the group adjusted restrictions to allow attendees to bring an empty reusable, non-metal water bottle to refill at the hydration stations located on the park grounds. Rachel Reisner, a spokesperson for Freedom 250, told CNN the group will be handing out water bottles.
Attendees are prohibited from bringing backpacks, coolers, folding chairs, drones, firearms or aerosols like in previous celebrations, but food and beverages will be available for purchase and handheld fans are allowed inside the perimeter. This year’s event outlines a clear-bag policy the group says is designed to speed up security screening.
Despite looming concerns of yet another attempt on Trump’s life, as well as the ever-present lone-wolf threat, Washington, DC, is well positioned to secure these sorts of large-scale events, several officials involved in the planning previously told CNN.
Federal agencies will also be helping protect several other July Fourth celebrations across the US, including in Boston, California, Pennsylvania and New York.
Attendees in Washington, DC, will be screened through security magnetometers. The Secret Service, which is taking the lead for the July Fourth event, along with the FBI, Metropolitan Police and other federal and local police, will be juggling security for Trump’s airshow as well as the “Great American State Fair” taking place on the National Mall.
With extensive road closures in the district, event goers are encouraged to take public transit. DC Mayor Muriel Bowser announced the Washington Metropolitan Area Transit Authority will be free after 5 p.m. ET and open until 2 a.m. ET.
The president’s attendance was a factor in making the celebration a National Special Security Event, USSS spokesperson Tom Lynch told CNN. The designation, also known as NSSE, is a common designation for major events that might be a target of criminals or terrorists. As a result, Lynch said the level of screening for this year’s celebration will be unlike any July Fourth in anyone’s recent memory.
Trump is expected to take the stage at 9:45 p.m. ET ahead of the 10:30 p.m. ET firework show, but the duration of his speech is unclear.
The president has billed the July Fourth event as a “Trump” rally and touted his prominent place in the Washington celebrations, despite criticism from Democrats that he’s turned the 250th commemoration into a partisan celebration more about him than the country.
Bowser initially announced the large annual fireworks show wouldn’t start until 11p.m. ET on the Fourth – two hours later than last year’s celebration, but the show will now begin at 10:30 p.m. ET and run for roughly 40 minutes.
The show is expected to set a new Guinness World Record for the largest firework display as nearly 850,000 fireworks shells will be launched from 10 sites spanning the Lincoln Memorial Reflecting Pool, Potomac River barges and West Potomac Park. The current benchmark is 810,904 fireworks at a 2016 New Years countdown celebration in the Philippines. The capital’s spectacle will be about 10 times bigger than Macy’s Fourth of July Fireworks Show in New York, which is typically the nation’s largest Independence Day bash.
The fireworks show is estimated to cost $850,000, CNN previously reported.
Fireworks create smoke pollution that sometimes rivals what comes from wildfires and can linger in the air for several hours. In some cities, air quality often doesn’t return to normal until around noon the next day, and the hot air could lengthen the process.
But even before any fireworks are lit in some urban areas, the heat will have already created another type of air pollution, ground-level ozone, formed from the mingling of vehicle exhaust, heat and sunlight. That ozone can irritate our lungs — potentially worsening air quality before any nighttime celebrations. Scorching locations, including in DC, are forecast to experience at least moderate amounts of ground-level ozone during the day.
When asked if the Environmental Protection Agency is tracking any air pollution impact as a result of the fireworks show, EPA press secretary Brigit Hirsch told CNN, “Fireworks are awesome and we hope everyone enjoys the incredible shows in and around our nation’s capital as we celebrate 250 years of America.”
For those watching at home, major networks will be broadcasting special coverage. CNN will have live coverage starting at 12 p.m. ET.
Fireworks are set to launch from the Lincoln Memorial Reflecting Pool – a site of much recent controversy and curiosity since blue material at the bottom of the pool began peeling off. The pool was painted blue and refilled after Trump ordered a $14-million renovation.
In the weeks following the costly vanity project, the president claimed that vandals damaged the algae-plagued Reflecting Pool and vowed to repair it. A former Olympic canoeist was indicted by a grand jury in Washington on Thursday for allegedly damaging the Reflecting Pool in front of the Lincoln Memorial. US Attorney for the District of Columbia Jeanine Pirro said Thursday that there are “about a half dozen” other cases the US attorney’s office is investigating.
