Central Kootenay D fire, July 2017 Central Kootenay D

Out · last detection 10 Sept 2017, 09:15 UTC

The fire started on 10 July 2017 in Central Kootenay D, Canada, and satellites saw it burning for 63 days. Canada’s CWFIS (Natural Resources Canada) mapped an official burnt perimeter of 3,848 hectares from satellite imagery, spread across a single census subdivision.

It is the 215th largest in British Columbia since 2016 (of 448 with a page). Number 109 in Canada in 2017, of 242.

Inside the perimeter there was no noticeable 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.

Frequently asked questions

How long did the Central Kootenay D fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 10 July 2017 to 10 September 2017 (63 days). The perimeter dates it from 10 July 2017 to 8 September 2017.
How much area did it burn?
The official perimeter mapped by Canada’s CWFIS (Natural Resources Canada) is 3,848 hectares (38.5 km²). Other tallies, such as those of provincial agencies, may give slightly different figures.
Which census subdivisions burned?
The fire only entered Central Kootenay D (3,822 ha, 0.6 %).
What was the weather like?
During the fire the temperature reached 33.0 °C, humidity dropped to 7 % and gusts hit 74 km/h. The fire danger index (FWI) reached 46, class Very high.
Where does this data come from?
From the official burnt perimeter of Canada’s CWFIS (NBAC, Natural Resources Canada) or, for the current season and until NBAC publishes it, the one rebuilt by GWIS (Copernicus); from NASA FIRMS VIIRS hotspots; and from the administrative boundaries of Canada. It is not an official report.

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.

Does something look wrong on this page?

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.

How we know this
  • Perimeter: NBAC (Natural Resources Canada), official.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 10 July 2017 to 8 September 2017. 1,144 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • 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.

How we build fire pages: methodology ›

Where this data comes from

The perimeter is official: it comes from the National Burned Area Composite (NBAC) of the Canadian Wildland Fire Information System (CWFIS), Natural Resources Canada, which maps it on satellite imagery and publishes it under the Open Government Licence – Canada. Until NBAC publishes the current season, this year’s fires carry the perimeter rebuilt from heat detections by GWIS (Copernicus, CC BY 4.0), which is approximate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Census subdivision boundaries come from geoBoundaries ADM3 (Open Data Commons Open Database License 1.0). The area per census subdivision is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from official figures.
