“This is Sky Valley Fire. Evacuation alert for Bolt Creek Fire. GO! No time for delay. Load up your family and pets and LEAVE NOW.”
Imagine getting an alert like this on your phone. Your heart immediately starts pounding; your hands shake. Is it real? Could this actually be happening? All the while, as your head spins, you’re losing precious minutes of time.
Luckily for many of the people who received this actual message last year in the Seattle suburbs, the “go now” alert was a mistake. But if you live in an area with anything greater than a “low” risk of wildfire, you should have a plan in place for what to do if that alert does come. It’s far better to “overreact” and leave immediately than to risk your life — and the lives of first responders.
The good news is, wildfire evacuation plans can begin long before your phone ever buzzes with that dreaded alert. Preparing for fire season ahead of time takes, cumulatively, as little as 90 minutes — but when a fire is encroaching, the math becomes far more urgent.
Importantly: Do not wait for an evacuation notice if you feel like a fire is approaching or like you could be in danger. Trust your gut and leave immediately. Though agencies do their best to protect people with advanced notices, fire is fast and unpredictable. In fact, many survivors of the deadly fire in Lahaina, Hawaii, say they did not receive evacuation orders before the flames had closed in on them.
Here’s what to do if there’s a fire in your area:
If you are experiencing smoke from a wildfire at your home, you should be paying attention to its development — the hazards of wildfires, after all, start with the smoke. If the fire is within 20 miles of you, you should definitely start paying attention; and if it is within 10 miles of you, it’s a threat. This threat increases if you are downwind or uphill.
Do not underestimate how fast a fire can move: 6 miles per hour in forests and up to 14 miles per hour in grasslands, depending on conditions. Embers, which can ignite homes, can also travel several miles, and wind direction can also quickly shift. If a nearby wildfire is approaching the 10-mile range of your home but you haven’t received a voluntary evacuation notice or don’t feel directly endangered yet, still review this evacuation checklist from the U.S. Forest Service. If you do receive a pre-evacuation alert or notice of some kind or want to take further steps to prepare, also:
Make sure you are signed up for emergency alerts or have another way of receiving updates, such as an agency website or Twitter account or a radio tuned into the correct station. Turn the sound on and up on your phone so you’ll hear the alarm or it will wake you up if you’re asleep.
Keep your car charged or filled to half a tank of gas or more. Scope out potential evacuation routes ahead of time, planning alternative routes in case roads are blocked or closed. Authorities say you should memorize at least two ways out of your neighborhood and avoid sketchy shortcuts that might be dangerous or blocked. Otherwise, take the quickest route to the main road, highway, or freeway out of the area.
Make a plan of where you’ll go if you need to leave your home for an extended period of time. A family or friend’s house? A hotel? A community emergency shelter? Open Red Cross shelters can be found here.
Open your garage door so you’re easily able to leave if you lose power.
Round up pets and secure them so they’re easy to put into carriers and transport to the car if you need to evacuate, and so you don’t waste precious time trying to chase them down when they’re scared. As the U.S. Forest Service notes, “this is especially important with cats.”
Prepare livestock and horses, if applicable, by reviewing this checklist.
Load up your car so you are prepared to leave on short notice. Remember to pack your go-bag (here is a version of the list in Spanish); suitcases of clothes and medicine (enough for at least a few days); pet supplies like collars, food, and water bowls; important files and back-up disks; insurance and bank papers; special or sentimental items; valuable jewelry or heirlooms (or store them in a fireproof safe); photo albums; and household items like keys and purses.
Too much to remember? Washington State suggests running through the Five P’s of evacuation: People, Prescriptions, Papers, Personal Needs, and Priceless Items.
Strongly consider leaving immediately. Roads can get congested after a mandatory evacuation order is issued, potentially creating dangerous situations where you’re trapped in your car near the fire. It will also get more difficult to see as the fire gets closer and the smoke gets thicker (always evacuate with your headlights turned on). Evacuating early also gives you time to calmly prepare a plan and collect essential items. If you’re on the fence, keep in mind it’s always better to leave too early than too late.
If you have time to prepare your house ahead of your evacuation, here is a checklist from the Western Fire Chiefs Association that you can use to get ready. Keep in mind that “the accepted sequence for safe evacuation is people first, then pets, livestock, and finally property,” Idaho Firewise writes. Major steps include:
Close all windows and interior doors to prevent the spread of fire indoors if the flames reach your home, and remove any curtains from windows. Close shutters and blinds. Leave your exterior doors unlocked so firefighters can get inside if need be.
Turn on all the main lights in your house as well as outdoor lights. This will allow firefighters to be able to see and navigate around your home in smoky conditions.
Push flammable furniture away from walls and windows and to the center of the room.
Shut off gas and turn off pilot lights. Don’t forget about pilot lights in gas fireplaces.
Attach hoses to outdoor water sources — firefighters will potentially use these to defend your home. The Western Fire Chiefs Association also recommends turning the nozzle to “spray” and propping a non-flammable ladder against your house to provide roof access. Fill buckets or garbage cans with water and leave them around your property if you’re able. However, you should not leave any water running, KQED notes, since that decreases the flow available to firefighters.
Prepare yourself for evacuation. California’s ReadyForWildfire.org recommends wearing “long pants, [a] long sleeve shirt, heavy shoes/boots, [a] cap, [a] dry bandanna for face cover [or a leftover COVID mask], goggles, or glasses,” and notes that “100% cotton is preferable.”
Finally, check on, text, or call neighbors and make sure they’re aware of the fire and also prepared to leave. Let them know you are choosing to evacuate. Also email, text, or call family who live outside the area and might be worried about you to let them know of your plans.
There is only one thing to do: Leave as fast as you can.
If you get an evacuation notice (or hear the high-low siren that also signals an evacuation order in California), do not waste time checking to see if the alert is real, gathering up items around your house, or making efforts to prepare your home. Your only focus at this point should be on getting to safety as quickly as you can.
Grab your go-bag and pets and get in your car; drive with the headlights on and follow the directions of any fire or emergency officials. If you need to evacuate on foot, quickly change into long pants, a long shirt, a cap, and heavy boots, and take essential items in a backpack or easily carried duffel bag. Know what to do if you get trapped near a wildfire. Be careful of downed powerlines or other hazards. And stay out of the area until officials say it is safe to return.

New York, New Jersey, and Pennsylvania advance a flurry of new ideas to manage the boom.
We know a little bit more about New York’s AI data center moratorium than we did yesterday. Here’s what stands out to me:
Governor Kathy Hochul says this won’t become a ban. “I’m not expecting the need for a ban. I want [the AI companies] to work with us,” she told Bloomberg’s “Odd Lots” podcast. “I understand how important AI is.”
The moratorium isn’t enough for some left-wing groups. As I wrote on Tuesday, Hochul’s order allowed her to avoid signing a more stringent moratorium that included wage requirements and renewable energy mandates for a much wider scope of projects. Kristen Gonzalez, a democratic socialist and a cosponsor of that bill, hailed Hochul anyway for “protecting everyday New Yorkers with a first in the nation moratorium on new large data centers.”
Some New York City progressive groups, while endorsing that more restrictive bill, suggested that she should have gone much further. The New York City chapter of the Sunrise Movement and other left-wing organizations, for instance, posted an Instagram carousel that said: “The dream isn’t better data centers. The dream is no data centers at all.”
New York is also exploring a grid acceleration fund. The governor’s order hints that a few policies should be in place by the time the moratorium ends. These include a new rule that data centers either bring their own power or “pay their fair share” for electricity, and a new state program to help local governments negotiate for community benefits with developers.
But it also opens the door for requiring projects to pay into a grid modernization fund. Such a fund could finance upgrades, set up new virtual power plants, or pay for new sources of zero-carbon energy, the order says. That idea — which resembles proposals from the Searchlight Institute and Groundwork Collaborative — suggests that the state is exploring ways to harness the AI boom for the public. “We want to make sure [data center developers] are investing in the grid,” Hochul said on Tuesday, “but they’re not being asked.”
Which brings me to my larger point. We’re seeing an efflorescence of interesting policymaking on data centers from Democratic governors and state legislators. New York has now enacted this moratorium, of course. Pennsylvania, a true national epicenter of data center construction, has passed new disclosure requirements, and Governor Josh Shapiro has pushed for serious reforms in the country’s largest electricity market.
In New Jersey — where surging power prices were central to last year’s gubernatorial election — the data center buildout has already produced a flurry of new laws. In its most recent session, the state legislature pared back tax incentives for data centers, required utilities to offer a rate for large electricity users, and required data center operators to publish water and energy data. It also set up a novel program that will let data centers pay to reduce electricity demand elsewhere on the grid, such as by setting up virtual power plants (or paying those who participate in them).
It’s been exciting to see different states — and, to be blunt, to see Democratic-governed states, particularly those in the Northeast and Mid-Atlantic — try to take on the data center boom. It’s good to see them test out ideas, solve problems through legislation, and harness this moment for the public good without strangling the buildout entirely. For too long, blue states have leaned into a particular economic model, one in which states want to attract varying forms of development but in fact succeed only in creating new suburbs, office buildings, and warehouses.
Soon after Democrats passed the Inflation Reduction Act, observers noticed that the law’s fruits — and notably its manufacturing investments — were sprouting in red or purple states, particularly in the Southeast and Sun Belt. The so-called Battery Belt bloomed in the Mid-South, for instance, not the Rust Belt. As I discussed with the political scientist Alexander Gazmararian on Heatmap’s podcast Shift Key, that was often due (counterintuitively, I think, for liberals) to a failure of governance: It is GOP-governed states that have the local expertise, institutional capacity, and political muscle memory to attract big new economic development projects.
If Democrats want to see their states do big things — build new housing and transit, decarbonize their power grids, or give birth to new industries — then they will need to develop the same kind of capability. That’s why I’ve so relished seeing blue states reckon with the data center boom. It should be encouraging that New Jersey policymakers, for instance, have to figure out how to manage a new and fast-growing industry on the technological frontier. Even questions that may seem troublesome right now — around land use, for instance, or how to relieve a congested power grid — will likely lead to policies that improve the state.
This kind of policymaking helps the Democratic Party, too. After all, the party’s future national leaders — its members of Congress, cabinet secretaries, and even presidents — are currently serving at the state and local level. The data center boom’s lessons — for good and ill — will resound among the party’s leadership for a long time.
Can she appease AI skeptics, economic development advocates, and renewables boosters?
New York Governor Kathy Hochul tried to pick out a middle way with her data center moratorium, carefully charting a course between the demands of industry, advocacy groups, and voters who are increasingly suspicious of the data center and artificial intelligence industries. Did she succeed? Only time will tell.
Hochul’s first-in-the-nation permitting pause has been hailed by data center opponents who want to re-orient American politics around the artificial intelligence backlash and lamented by the technology sector and its allies, including several in the Trump administration. President Donald Trump himself wrote on Truth Social, “New York State has made a terrible decision.” adding that the “Radical Left Dumocrats must not be allowed to cause us to lose Data Centers, AI, and all of this incredible new Technology, to China.”
Before we discuss what Hochul did, we must first discuss what she didn’t do.
What Hochul’s moratorium is not is her signature on the Responsible Data Center Development Act, a data center moratorium that passed both houses of the state legislature in June. That moratorium had a lower energy use threshold for the moratorium: 20 megawatts, compared to Hochul’s 50 megawatts.
One of that bill’s sponsors, democratic socialist Kristen Gonzalez, appeared alongside Hochul when she signed the executive order Tuesday and hailed the governor for “protecting everyday New Yorkers with a first in the nation moratorium on new large data centers.” When asked about this discrepancy by reporters, Hochul said that “we want to make sure we didn’t touch the data centers that are powering hospitals and schools and research centers,” and specifically mentioned data centers used by “bank back-office operations.”
Protecting bank back-office operations is not typically top of mind for democratic socialists. Gonzalez’s office did not respond to a request for comment.
The goal of the moratorium, Hochul said, is to develop a process for data centers to pay their way in terms of grid costs and electricity rates.
“We expect this process, which we already launched, to be completed within the year,” she said. “Once this policy’s in place, the moratorium will be reviewed and lifted.”
What is still unclear is how this moratorium interacts with renewables development, especially upstate where there is enough open space for both wind and solar power as well as large data centers.
While the New York governor has pulled back on the state’s climate goals as renewable energy and transmission has come under the dual assault of the Trump administration and rising costs, Hochul has made a point of promoting clean power development across the state, especially nuclear and hydropower, which can be built and maintained close to her western New York home base.
A New York data center industry could — emphasis on could — be a major customer for renewable power in the state, especially as there’s little prospect of large-scale new natural gas development.
During her speech announcing the moratorium, Hochul emphasized that “we’ve invested so much in other forms of power to meet the current needs of New Yorkers and our businesses,” and that “New York will require data centers to either produce their own energy or pay a premium to tap into our grid.”
The executive order itself lays out a process whereby, once the moratorium is lifted, new data centers may be required “to fund new clean electric generation and/or battery storage dedicated to their operations, consistent with the State’s clean energy goals, including customer-sited distributed energy resources, to the greatest extent feasible.”
When discussing her energy and economic policies on Bloomberg’s “Odd Lots” podcast this week, Hochul connected her data center moratorium with economic development efforts, especially upstate, where large data centers are more likely to be sited.
Referring to Micron’s $100 billion Syracuse-area semiconductor manufacturing project, Hochul told hosts Joe Weisenthal and Tracy Alloway, “I’ll work with you to get the power you need.” (The state approved a transmission line for the project last year.)
“If I have to choose between powering a largely vacant data center with the same amount of power I can have with a Micron with 1,000 jobs, I can tell you right now where I’m going,” Hochul said. “They can come under the conditions we lay out.”
But it may be just as likely data center developers take the hint and avoid a state with expensive power and high costs of doing business in the best of times.
“I don’t think we know yet how this will impact what’s known as behind-the-meter or off-the-grid power solutions: natural gas, cogeneration, solar, wind, battery storage,” Jeffrey Moerdler, a partner at the law firm Haynes Boone who chairs the data center practice, told me. “I assume it will hold up data centers powered by alternative energy sources.”
As for whether Hochul can successfully keep the one-year moratorium a year (temporary policies have a tendency to become permanent), develop new rules to address her concerns about grid costs and local opposition, and then have data centers line up to get back into New York, Moerdler was skeptical.
“It’s going to take years to make up for that shift” against data center development, he told me, predicting that the moratorium could lead to “many years of new data centers not locating here because they already started during that one-year period somewhere else.”
Something else that must be noted in all of this: “New York is not a high priority location for data centers.” Whether the state’s governor wants it to be remains to be seen.
Where is the smoke worst, where will it go next, and what causes that color?
Before wildfire smoke turns the skies to a jaundiced yellow-gray, it might look almost pretty. Midday light grows diffuse, taking on a crepuscular golden hue. Shadows soften and stretch long. The sunsets are particularly incredible: radiant, neon red.
But as with oleander and poison dart frogs, beautiful things are often the most dangerous. The same wildfire particulates that scatter the light will, once dense enough, turn the air around you orange, then black. They will get into your lungs — slipping past your nose hairs and mucus, the body’s defenses that stop larger particulates — and provoke your immune system into an attack. The tiny air sacs at the ends of the bronchioles in your lungs, where the gas exchange of “breathing” actually happens, will become inflamed. You will become short of breath. You will cough. The smallest smoke particulates may even enter your bloodstream.
And if you are like 24,000 other Americans every year, this will kill you.
Though wildfire smoke exposure might seem to be more of a nuisance to a healthy person than anything else, experts agree it should be taken seriously. “In my profession, wildland firefighting, you make a decision that you run into that,” Nicholai Allen, a firefighter and founder of Safe Soss, a home-hardening product line, told me. “But for my family and my children, I don’t want them breathing in the smoke that’s traveling that far. We have air purifiers, and we’re taking similar precautions.”
On Wednesday, more than 100 million people in the Midwest and Northeast face unhealthy smoke conditions from fires burning up to 2,000 miles away. Here’s what you need to know.
The smoke is largely coming from 150 or so lightning-ignited fires in Ontario and northeastern Minnesota. Triple-digit temperatures, dry conditions, and high winds have fanned a “wall of fire” across the region, as the firefighting newsletter The Hotshot Wakeup put it, even as Canada is, on the whole, tracking behind its five-year average for area burned so far. Most of the fires sending smoke to the U.S. this week are still out of control and spreading rapidly.

A high-pressure area over the central U.S. and a low-pressure area over Eastern Canada are acting as a funnel, pulling bad air east across the Great Lakes region and into the populous Acela Corridor. Conditions are worst closest to the fires: Around 8 a.m. on Wednesday morning, Duluth, Minnesota had a “hazardous” air quality rating of 785 out of 800. By the afternoon, Toronto had the worst air quality of any major city in the world, and drivers in northern Michigan have been advised to slow down and turn on their low-beam headlights because visibility has been so reduced by the smoke. The eastern-moving plume has also blanketed large portions of Upstate New York.
Degraded air quality reached the Boston and New York City areas on Tuesday night and is expected to linger through Thursday. The smoke reaches as far north as Maine, having dimmed the morning light in New Hampshire, and could spread as far south as Washington, D.C. over the next 24 hours.
Though the smoke is staying largely to the north over the middle part of the country, forecasts show it could dip into downtown Chicago on Thursday as well.
Wednesday and early Thursday will be the worst days for the eastern U.S., per the current outlook. A cold front should help push the worst of the smoke out of the region as we head into the weekend.
So far it appears that much of the smoke has remained high enough in the atmosphere that while you’ll be able to see and likely smell it, it might not cause extreme air quality problems on the ground. As of Wednesday afternoon, New York City was recording some of the worst air on the East Coast, with an air quality index of around 160 — bad enough to trigger an “unhealthy” alert for the general public and to rank fifth-worst among major cities worldwide. The rest of the region still mostly showed orange readings designed to alert sensitive groups such as older adults, people with respiratory conditions, and pregnant women, or more moderate yellow ratings.
Conditions could still change, though. Heat, pressure, and winds can drive smoke down to ground level, where it becomes a threat to public health. In fact, the Fox Forecast Center’s models indicate that particulate matter concentrations around the Great Lakes and Northeast could be on par with the 2023 East Coast smoke event, during which New York had the world’s worst air quality, although The New York Times reports that “even the most severe forecasts” this week should not approach that level.
The best thing to do is to continue monitoring your local air quality. If you want help navigating what those readings mean, my colleague Emily Pontecorvo has written a great explainer.
For many on the East Coast, the orange skies are a flashback to the 2023 smoke event. While eerie and apocalyptic, the smoke also gives us an excuse to talk about Mie theory.
Air molecules are much smaller than the wavelength of light. When white light from the sun enters the atmosphere, nitrogen and oxygen scatter the short, higher-frequency blue light in multiple directions. This is known as Rayleigh scattering, and is also the answer to, “Why is the sky blue?” Under normal conditions, wherever you look in the sky, blue light is headed toward your eye.
Smoke particles, while small enough to enter our lungs when inhaled, are larger than air molecules — about the same size as light wavelengths. Because these particles are larger, they also scatter light more democratically, including the lower-frequency, longer reds and oranges. This is called Mie scattering. When sunlight passes through smoke, the reds, oranges, yellows, and blues are all mixed together as they reach our eyes, appearing as a hazy gray or white.
You might expect thicker smoke to result in a darker gray, then. But smoke also contains organic compounds from burned plants called brown carbon, plus soot, both of which absorb visible light. Brown carbon, in particular, prefers light at the shorter end of the spectrum, absorbing about three-quarters of the total light at blue wavelengths in smoke plumes, compared to about half at red wavelengths. That means that when the smoke thickens, the blue light doesn’t reach our eyes nearly as well, and the sky takes on an orange appearance.
One of the dangers of the current smoke event is that it coincides with high temperatures across the Central U.S. and New England. Both conditions together — high heat and smoke — can lead to some confusion over how to respond.
The best strategy is to keep your windows closed. But while it might feel safe side, wildfire smoke can still degrade indoor air quality. “If you have a fresh air intake on your air conditioning system, I would shut that off so that you’re recirculating just your purified air inside your house,” Allen, the firefighter, told me.
You can also install activated carbon exterior filters on attic and crawl space vents and run a purifier with a HEPA filter. (If you bought an air purifier during the last smoke event, consider this your reminder to replace your filter.) “Then I would avoid going outside or exercising outside if there’s smoke in the air,” Allen added. “When the particles are arriving to you from a great distance from the wildfire, they are the smaller particles that can get in your lungs. So not to create undue fear, but there’s definitely stuff in that air that you don’t want to breathe.”
