Is there a November 17 blackout? The viral Simpsons clip and the FEMA alert test, checked

What's being shared

On November 1 an X post told viewers to watch the last 15 seconds of a Simpsons episode, "It's a Blunderful Life," claiming it predicted a "Great Blackout" on November 17. Insider Paper reports the post showed more than 1.5 million views. Earlier posts, collected by Primetimer on October 30, had already linked the clip to FEMA's announcement of a nationwide test on November 17, with users saying they were "scared" of what would happen that day.

A Facebook Reel, IBTimes reports, adds other coincidences: a UK government campaign that asks households to prepare for three days of disruption, and the number of days between the date and the 2025 inauguration. IBTimes checked both and found no link between them and any blackout. This page sticks to the two things that can be checked: what is scheduled on November 17, and what the episode shows.

What is actually scheduled on November 17

FEMA, in coordination with the FCC, will conduct a nationwide test of the Emergency Alert System (EAS) at approximately 2:20 p.m. Eastern Time on Tuesday, November 17, 2026. FEMA says the test will last approximately one minute. The message, in English and Spanish, will say: "This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency. This is only a test. No action is required by the public."

The FCC's public notice, released on September 16, lists who carries it: radio and television stations, cable systems, satellite radio and wireline video systems. FEMA says these tests check whether broadcasters and other providers can receive and pass along emergency messages. It is not a test of the power grid. The FCC's notice does not mention phones, and FEMA has said the test will not send alerts to mobile phones, Insider Paper and Primetimer report. If conditions on November 17 require it, the FCC says the test will be rescheduled to December 3, 2026.

Federal law requires a national test at least once every three years, FEMA says. The previous one was on October 4, 2023, when FEMA tested both EAS and the Wireless Emergency Alerts that go to phones. Our emergency alerts guide explains how the alert systems work and how to check your phone's settings.

What the Simpsons episode actually shows

"It's a Blunderful Life" is the seventh episode of season 35, first shown on November 19, 2023. Insider Paper, citing Laughing Place's review from when it aired: Mr. Burns accidentally starts a fire at the nuclear plant, Springfield loses power shortly before Thanksgiving, and the town blames Homer. Burns is later exposed, Homer is forgiven, and the family gets its Thanksgiving dinner. The outage is the setting for a story about blame and family loyalty, and IBTimes notes the "great blackout" is recalled by Lisa 60 years in the future, which is where the phrase in the posts comes from.

The viral posts say the episode's final seconds name November 17. Insider Paper says that specific claim has not been independently verified, and Primetimer notes the circulating video also splices in scenes from a different episode, "Bart's Birthday," in which characters keep switching lights off. A cartoon about a holiday power outage from three years ago is not a forecast, and the show's writers have no say over the grid.

Is any outage planned that day?

We looked for one and found nothing. FEMA's and the FCC's notices describe a communications test only. We found no announcement from any grid operator or utility we checked of a planned outage on November 17, and no federal advice telling households to prepare for that date. The FCC's notice was published on September 16, well before the November 1 viral post, Insider Paper notes.

For the bigger question behind the rumor, our guide to whether a national blackout could happen explains how the three US grids are built and what NERC's reliability assessments actually say. And if you've seen the related claim about a 90-day blackout, we checked that too: it comes from a Pentagon plan for military bases, not a warning to households.

What households can sensibly do

Nothing about November 17 changes official advice. Ready.gov says that after an emergency you may need to survive on your own for several days, with your own food, water and other supplies. CDC says to store at least 1 gallon of water per person, per day for 3 days, and to try to store a 2-week supply if possible. For scale, EIA says US electricity customers averaged 11 hours of interruptions in all of 2024.

If the rumor has made you look at your own readiness, that is the one useful thing to take from it. Start with our power outage checklist and how much water to store, or size a kit for your household with the kit builder. On the day itself, expect a one-minute test message on radio and TV at 2:20 p.m. ET and nothing more.

• Water: at least 1 gallon per person, per day, for 3 days; a 2-week supply if possible
• Food: at least a several-day supply of non-perishable food your family will eat
• Flashlights for every household member, plus extra batteries
• A battery-powered or hand-crank radio, so you hear real alerts in a real outage
• A power outage plan, made with your medical provider, for any medical devices powered by electricity and refrigerated medicines

What not to do

Don't buy a generator, months of food or anything else because of a date in a viral post. Ready.gov's advice is to store foods your family will eat. If you were planning to buy backup power anyway, our power station vs generator guide explains the choice, and the generator safety guide covers the rule that matters most: CDC says never to use a generator, pressure washer or any gasoline-powered engine inside your home, basement or garage, or less than 20 feet from any window, door or vent.

And don't share the clip as a warning. If someone sends it to you, the FCC's notice is the quickest answer.
