Radar outages and maintenance

Marble Mountain - XME Atlantic NL Site is offline due to radar replacement. Due to the small footprint of available land at this mountaintop site, the old radar must be removed before the new one is built. Also, due to the high winds and short construction season at this location, the construction must be split into two phases spanning the calmer summer weather in 2021 and 2022. In anticipation of this lengthy radar outage, two nearby radars (Holyrood, NL and Marion Bridge, NS) will have their range extended from 240 km to 400 km to provide meteorologists with additional radar data in this area. ECCC Meteorologists use many data sources to detect and track severe weather—radar is just one of them. When radar data is unavailable, meteorologists use other tools such as satellite images, surface weather stations, lightning detectors, severe weather spotter reports and sophisticated computer models. Weather warnings and forecasts will continue to be issued during any radar outage period. 2021-05-27 2022-10-15

Victoria Pacific BC Suffered a major hardware failure, will be replaced with a new modern radar and moved to a better location providing improved coverage for the area. The new radar is tentatively planned to be operational in 2022. Until then, the radar image will be displaying data combined from seven neighbouring radar sites (including US radars). 2017-11-18 -

Radar outage

Every two months or so, radars are taken off line for routine maintenance. This maintenance is scheduled during times of low likelihood of severe weather. Occasionally, radars also go offline due to a mechanical, electrical, technical, or telecommunications related problem.

New radar installations

The Government of Canada announced on February 28, 2017, the replacement of its weather-radar network. During the construction period, until the new radar becomes fully operational, the radar image for that location will be displaying data combined from neighbouring radar sites (including US radars). For more information on this project please visit the following page: Modernizing Canada’s weather-radar network.

In case of an outage

We continue to provide weather services by using data from neighbouring radars since, wherever possible, the coverage of the radars has been designed to overlap.

The figures below show an example of the area covered by Superior West radar and a composite image (also called contingency product) built from two Canadian and two American radars during an outage of this radar. We can see that these four radars overlap each other's in many areas. The red circles will be activated on the image only if the contributing radars to the composite image are available.

In addition to our radars

For areas with no radar overlap, a variety of other tools help meteorologists detect and predict severe weather:
