Radar is one of the key tools among many used by meteorologists to forecast severe storms. That increase has been felt by many in western Canada, with flooding events that devastated British Columbia in November 2021, severe storms causing flooding in Calgary and Saskatoon this past summer, and the record hail in southern Alberta in August. Studies also show that large hail events could also become more frequent. Active weather and climate changeĪccording to a report by Environment and Climate Change Canada, "extreme weather presents the most immediate climate risk for the Prairie provinces, as is evident from the catastrophic events that have taken place over the last decade."Īn overall increase in temperatures allows summer storms to hold more water, which means that in the future, high precipitation events are more likely.
WEATHER NETWORK RADAR EDMONTON UPGRADE
The Fort McMurray site is the only new radar installation. Canada's radar network will now consist of 33 sites across the country, with the entire network upgrade slated to be complete by March 2023. The new site near Fort McMurray now means radar information extends to Fort Chipewyan, Alta., 300 kilometres north, and out to Buffalo Narrows, Sask., about 275 kilometres to the southeast.
The project began in 2017, with the upgrade of the site at Radisson, Sask., 65 kilometres northwest of Saskatoon. The most recent round of improvements will effectively double the severe-weather detection range. "So we are totally and completely expanding radar coverage over northeastern Alberta, northwestern Saskatchewan."Īccording to Hoffman, the installation is part of a $140-million nationwide project to upgrade and replace the aging radar network with dual-polarization - often referred to as "dual-pol" - radar. "There was no pre-existing radar here," says Sara Hoffman, a meteorologist with Environment and Climate Change Canada. That's why Environment and Climate Change Canada's newest radar site near Fort McMurray, Alta., which officially came online in late September, is seen as such an important piece in the weather and climate jigsaw puzzle.
As our climate continues to change, accurately tracking severe weather is critical.
