New Smoke Forecasts

March 31, 2021

The four BlueSky Canada daily smoke forecasts have been upgraded with a larger domain, improved meteorology, and are now being produced using the new BlueSky Pipeline (BSP) modelling framework.

  • The larger domain extends farther north, south and west and will improve the forecast by incorporating more emissions sources.
  • The new meteorology extends the high-resolution 12 km forecast grid over more of the domain, and allows the use of nested 36 km meteorology instead of requiring interpolation during dispersion modelling.
  • The new BSP framework improves emissions modelling and the integration of carryover smoke from previous forecasts.
  • The BSP framework also positions BlueSky Canada to take advantage of new plume rise research and model development currently underway to further improve smoke forecasts.

New Fire Weather Forecasts

March 31, 2021

The beta BlueSky Canada Fire Weather Forecast (FWF) model is now operational and producing daily forecasts. The FWF is an impementation of the Fire Weather Index (FWI) System using BlueSky Canada gridded metorological forecasts, providing high-resolution spatial and temporal FWI forecast output for use in operational wildfire models and wildfire incident command briefings.

  • FWI fuel moisture codes and indices are calculated at up to 4 km grid resolution with a two day forecast horizon.
  • Weather-sensitive moisture codes and indices are resolved at one-hour temporal resolution, while less sensitive codes and indices are resolved once daily at noon local time.
  • The FWF is available as an interactive map with point forecast functionality and active model comparison to observed meteorology and FWI values.

More information about the FWF model is available at cerodell.github.io/fwf-docs/build/html/index.html.

Service Interruption

October 7, 2020

There will be a firesmoke.ca service outage on Saturday, October 17, 2020 from 07:00 to 16:00 Pacific Time due to network maintenance. We recommend you load a smoke forecast into your browser on Friday, October 16 if you need one during the interruption.

HTTPS Available

April 1, 2020

A secure, encrypted version of this website is now available at https://firesmoke.ca/. For legacy compatibility reasons, the original unencrypted HTTP site will remain operational, and it will not be automatically redirected to the HTTPS site.

New Forecast Viewer

May 15, 2019

A new and improved forecast viewer has been released. Improvements include new basemap layer choices, better playback controls, a new fire outline overlay, new hotspots marking and clustering, an opacity control for the smoke layer, and a sidebar with comprehensive forecast and help information. Concurrently, we also simplified the forecast graphics to use six levels to make it easier to see transitions and to make the PM2.5 values relate to national exposure standards. You can see the new viewer by visiting the current smoke forecast.

New Forecast Colour Scheme

April 3, 2019

We have switched to a YlOrBr (yellow orange brown) colour scheme to display the different levels of PM2.5 on our smoke forecasts. This was done to improve accessibility for colour blind users and to improve contrast between levels when viewed in grayscale. Here is the new forecast legend we are using:
