The fire started on 10 May 2017 in Cuauhtémoc, Mexico, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,344 hectares from heat detections, spread across a single municipality. According to CONAFOR, it was detected on 10 May 2017 and declared extinguished on 15 May 2017.
It is the 26th largest in Chihuahua since 2016 (of 229 with a page). Number 29 in Mexico in 2017, of 374.

27.7°C · 14% RH
High of 27.7 °C and minimum humidity of 14% on 13 May 2017; gusts of 76 km/h on 16 May 2017.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.

A lede of about 60 words figures only, no adjectives
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Inside the perimeter there were about 1.0 hectares of built-up land and almost nobody lived there (GHSL 2015, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.
According to CONAFOR, this fire started on 10 May 2017 and burned 8,484 ha (the satellite measured 8,344 ha).

It was 3.2 times larger than the median of its twins and lasted 7 days, against 6 days.
Only 4 of its 15 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 7 of 15, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 4.0 mm.

How a twin is chosen
Same area: fires that have already ended, less than 250 km from this one, since 2016.
Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
They are sorted by similarity, and the outlines of the first five are drawn.
GWIS (Copernicus) dates it between 10 May 2017 and 16 May 2017: 7 days between the first and last heat detection of the perimeter. According to CONAFOR, it was detected on 10 May 2017 and declared extinguished on 15 May 2017.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 8,344 hectares (83.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Cuauhtémoc (8,390 ha, 2.3 %).
What was the weather like?
During the fire the temperature reached 27.7 °C, humidity dropped to 13 % and gusts hit 76 km/h. The fire danger index (FWI) reached 96, class Very extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mexico (geoBoundaries). It is not an official report.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 15. Their median duration was 6 days and their median area 2,623 ha; 100 % went past 1,000 ha. Only 4 of its 15 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 7 of 15, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 4.0 mm.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
Dates from the perimeter: the VIIRS detections inside it did not change them. 331 Suomi-NPP VIIRS detections on those dates.
Compared with CONAFOR: 8,484 official ha against 8,344 ha of perimeter; they agree within 25%.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 4.0 (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
