Whatever region you live in, the France fires are a window into what runaway wildfire looks like at its most extreme. The largest blaze in the Bordeaux region started July 22 and has since chewed through 160 square miles of forest and scrubland — an area bigger than the city of Atlanta, Georgia. More than 240 homes have been damaged or destroyed, and 200,000 people have been uprooted from their communities.

That scale of displacement is hard to absorb. On Tuesday alone, 4,000 more people — including tourists on vacation in the region — were forced to leave. Evacuation centers in Bordeaux filled with families who had hours, sometimes minutes, to grab what they could and go.

How Much Do You Know About Extreme Wildfires?

Five questions. The answers reveal how these fires are rewriting the rulebook — and what it means for communities across the country.

France recorded its first ever 'fire cloud' during this crisis. What makes a fire cloud dangerous beyond the fire itself?

• It blocks aerial firefighting aircraft — Visibility is a factor, but the more dangerous feature is what the fire cloud generates from within — the fire cloud produces its own violent, erratic winds and lightning, which can spark entirely new fires in areas not yet burning.
• It generates its own lightning and erratic winds — Correct. The Bordeaux fire cloud — France's first ever — created its own internal weather system, producing lightning that ignited additional fires and unpredictable winds that made the existing blaze far harder to contain.
• It carries embers hundreds of miles downwind — Ember spotting is a real wildfire risk, but it is not what makes a fire cloud uniquely dangerous. The fire cloud's defining threat is the self-generated lightning and violent winds it creates — which is what made this event historic in France.
• It causes acid rain that damages crops — Not the mechanism here. The fire cloud in Bordeaux was dangerous because it functioned as its own localized weather system, generating lightning that sparked new fires and erratic winds that complicated firefighting efforts.

The largest Bordeaux fire has scorched 160 square miles. Which U.S. city is that roughly equal to in size?

• Atlanta, Georgia — That's right — the fire area is larger than the city of Atlanta. Putting the number in geographic terms makes the scale of the destruction immediate: imagine an entire major American city reduced to burned forest and scrubland.
• Denver, Colorado — Denver is larger than the burned area. The fire's footprint — 160 square miles — most closely compares to the size of Atlanta, which reporters and officials used to illustrate just how vast the destruction has become.
• Pittsburgh, Pennsylvania — Pittsburgh is a smaller city. The benchmark used in reporting is Atlanta — a major metro whose footprint gives a vivid sense of how much land 160 square miles of burned forest actually covers.
• San Francisco, California — San Francisco is famously compact at about 47 square miles — far smaller than the fire zone. The Bordeaux blaze is larger than Atlanta, which is the comparison reporters and officials used to convey the fire's scope.

While France battles its fires, neighboring Spain is also dealing with a deadly season. How many people have died from wildfires in Spain this year?

• 5 — The toll is higher. At least 13 people have died from wildfires in Spain this year, making it one of the deadliest fire seasons in decades — and the crisis is still ongoing as officials work to lift evacuation orders for some of the 80,000 people displaced there.
• 13 — Correct — at least 13 people have died in Spain from wildfires this year, a toll officials describe as one of the worst in decades. Meanwhile, nearly 80,000 people were forced to evacuate across the country, a number that dwarfs even the enormous French displacement.
• 30 — The confirmed death toll from wildfires in Spain this year is at least 13 — devastating, but not as high as 30. Officials have called it one of the deadliest fire seasons in decades even at that number, with evacuations still affecting tens of thousands.
• It has not reported deaths — Spain has reported deaths. At least 13 people have died from wildfires in the country this year — a toll that officials say makes this one of the deadliest fire seasons in decades, even as some evacuation orders begin to lift.

Firefighters in France are working under triple-digit temperatures. What two weather factors are forecast to make conditions worse in the coming days?

• High humidity and strong ocean winds — High humidity would actually help slow a fire — it is the opposite of what officials are warning about. Forecasters have flagged high temperatures AND dry air as the combination that will create the most dangerous conditions in the coming days.
• High temperatures and dry air — Correct. Officials warned that high temperatures combined with dry air will create unstable conditions in the days ahead — the same pairing that helped ignite and sustain the current fires. Fourteen new fires were already sparked on a single Tuesday during these conditions.
• Lightning storms and flash flooding — Lightning was a factor — but created by the fire cloud itself, not a separate storm system. The forecast threat officials cited is high temperatures and dry air, not flooding. Wet conditions would actually be welcome in slowing the fires.
• Falling temperatures and fog — Falling temperatures would be good news for firefighters, not a threat. Officials specifically warned that high temperatures and dry air — not cold or moisture — are forecast to create the most dangerous upcoming conditions.

How many firefighters are currently deployed across the Bordeaux region to fight these blazes?

• Roughly 500 — The actual deployment is six times larger. Some 3,000 firefighters are working throughout the region — battling blazes in triple-digit temperatures and racing to prevent fires from spreading further before worsening weather arrives.
• About 1,500 — Twice as many firefighters are on the ground. Some 3,000 are deployed across the region, working under extreme heat to contain blazes that officials say are mostly under control but not yet fully extinguished — a critical distinction.
• Around 3,000 — Correct — 3,000 firefighters are deployed throughout the Bordeaux region. They are operating under triple-digit temperatures, battling blazes that officials describe as mostly under control but not fully extinguished, with unfavorable weather on the way.
• More than 10,000 — The deployed force, while large, is 3,000 firefighters — not 10,000. That number is working to contain fires across a region where 14 new blazes sparked in a single day, all while enduring triple-digit temperatures on the ground.

That's the firefighting picture that makes the Bordeaux crisis so alarming: 3,000 trained responders, working in triple-digit heat, battling blazes that officials describe as mostly under control but not fully out — with worse weather on the horizon. Fourteen new fires sparked in a single Tuesday. High temperatures and dry air are forecast to continue, creating the same unstable conditions that let this all begin.

The fire cloud — France's first ever — is the detail that separates this season from anything the country has seen before. A fire intense enough to generate its own internal weather system, producing lightning and violent winds, is no longer just a wildfire. It is a self-sustaining atmospheric event.

France vs. Spain: Two Countries, One Crisis

How the Crisis Unfolded

• July 22 — Largest fire ignites in Bordeaux region
• Days after — Fire grows past 160 square miles — larger than Atlanta
• Ongoing — France's first ever fire cloud forms, generating its own lightning and violent winds
• Tuesday — 4,000 more people evacuated, including tourists on holiday
• Tuesday — 14 new fires spark in a single day
• Tuesday — Spain begins lifting some evacuation orders for 80,000 displaced residents
• Coming days — High temps and dry air forecast — officials warn of continued unstable conditions

The Scale of Europe's Fire Season

• 200,000 — Evacuated in France
• 160 — Square Miles Burned
• 80,000 — Evacuated in Spain
• 13 — Deaths in Spain

In Spain, recovery is tentative. Officials have started lifting evacuation orders for some of the 80,000 people who fled — but at least 13 people have already died from wildfires this year, a toll officials are calling one of the deadliest in decades. The fires have not stopped; the worst of the season may not be over.

Across the Atlantic, the numbers from Europe carry a familiar weight for American communities that have lived through their own fire seasons. The combination driving this crisis — extreme heat, dry air, and weather systems that a fire large enough creates for itself — is not unique to any one continent.

What's True About This Fire Season

The Bordeaux fire is bigger than the city of Atlanta.

Verdict: true

The fire has scorched more than 160 square miles of forests and scrubland — an area explicitly compared to Atlanta's size in reports from the region.

Most fires in France are now fully extinguished.

Verdict: false

Officials say most fires are currently under control — but 'under control' and 'fully extinguished' are very different. The fires have not been put out, and 14 new ones sparked on Tuesday alone.

France has seen fire clouds before.

Verdict: false

The fire cloud produced by the Bordeaux blaze is the first ever recorded in France. This rare phenomenon — where a fire generates its own weather including lightning and erratic winds — is a historic first for the country.

Wildfire conditions in Europe are expected to improve soon.

Verdict: false

Forecasters say high temperatures and dry air are expected in the coming days — the same conditions that created the crisis. Officials have warned that weather conditions will remain unfavorable for controlling the fires.

What to Know If You Live in Wildfire Country

1. Understand what 'under control' actually means — Officials in France described most fires as 'under control but not fully extinguished' — a critical difference. A fire under control is contained, but still burning. Know the terminology before it matters near you.
2. Watch the weather, not just the fire — The France crisis was worsened by forecast high temperatures and dry air. Wildfire danger follows weather — know when your local conditions become high-risk.
3. Have an evacuation plan before you need it — In France, 4,000 people — including tourists — were evacuated in a single day with little warning. Know your exit routes and where you would go.
4. Take fire cloud warnings seriously — A fire cloud generates its own lightning and violent winds, which can spark entirely new fires in unpredicted locations. If fire weather warnings mention pyrocumulonimbus activity, treat it as a different-level threat.

What Is a Fire Cloud — And Why Is It So Dangerous?

A fire cloud — known scientifically as a pyrocumulonimbus cloud — forms when a wildfire burns so intensely that the heat and smoke generate an enormous column of rising air. As that column reaches the upper atmosphere, it can develop the same characteristics as a thunderstorm: clouds, violent winds, and lightning.

What makes this so dangerous is that the fire is no longer just reacting to weather — it is creating weather. The lightning a fire cloud generates can strike areas far from the original blaze, starting new fires that firefighters had no way to anticipate. The erratic winds it produces can redirect the original fire unpredictably, trapping crews or residents who thought they were in a safe zone.

France's first recorded fire cloud, produced by the Bordeaux blaze, is the kind of extreme fire behavior that fire scientists say will become more common as conditions that sustain large fires — heat, drought, and dry air — intensify.

Follow the Crisis

• Stay Current on Wildfire Conditions: Check your local emergency management agency for wildfire watch and warning status in your area, especially during periods of high heat and low humidity.
• Know Your Evacuation Zone: In France, 200,000 people were evacuated — many with little notice. Register with your local emergency management office to receive evacuation alerts before a crisis begins.
• Read the Full Scripps News Investigation: Scripps News is tracking the France and Spain wildfire crises and how extreme fire behavior is changing emergency response globally.

The fires burning through Bordeaux are not just a European story. They are an early and vivid look at what happens when the conditions that drive wildfires — heat, drought, dry air — combine with terrain and a moment of ignition. The fire cloud France recorded for the first time in its history is not a one-country phenomenon. It is a new chapter in how wildfires behave.

For the 200,000 people who left their homes in France, and the 80,000 who fled in Spain, the data points above are not statistics — they are neighborhoods, vacations interrupted, houses gone, and 13 people who did not make it out. That's the number that stays.
