Edmonton’s soggy summer has officially set a new seasonal record.
The news from Environment Canada comes as the city mops up from a Saturday evening storm that rolled through the capital city region, dropping 30 millimetres of rain from 9 p.m. to 10 p.m. Though wind speeds averaged 39 km/h during that time, a maximum speed of 94 km/h was recorded by Environment Canada, said meteorologist Jennifer Kowal.
After the weekend storm, Edmonton has seen 503.7 millimetres of rain this summer, Kowal told CBC News on Monday. The previous rainfall record was 417.1 millimetres in 1953.
“It really looks like the increased temperature this summer and the water on the ground is going to just continue this pattern, at least for the foreseeable future,” said Kowal.
The Saturday storm came after multiple severe thunderstorm warnings and watches were issued by Environment Canada for much of central Alberta, including Edmonton.
The powerful storm closed roads, flooded neighbourhoods, shut down outdoor events and downed trees, according to a statement issued by the city on Monday.
At the peak of the downpour, around 37,700 Epcor customers went without power, the company said in a statement to CBC News, adding that most outages were in the west end and in neighbourhoods just north of the downtown core.

The most recent major storm in Edmonton happened on Saturday, bringing floods, sewer backups, power outages, and fallen trees and branches throughout the city. Environment Canada says about 30 millimetres of rain fell during the storm, which brought winds of up to 84 kilometres per hour. Kyle Brittain is an Alberta-based weather specialist.
Post Malone concert cancelled
One of the Saturday night’s biggest incidents took place at Commonwealth Stadium, where American rapper Post Malone was playing his second of two back-to-back concerts at the outdoor venue.
Saturday’s rainfall damaged parts of the stadium and sent about 31,000 fans scurrying for cover.
Stadium staff used audio messaging and the venue’s jumbotron to ask attendees to move to the open-air buildings into sheltered areas, such as the stadium’s concourse which the city said is large enough to hold the fans.
“The safety of fans, staff, crew and artists is of utmost importance,” the city said in its release.
All of Commonwealth Stadium’s emergency protocols were followed, and no injuries were reported, according to the city.
The concert was ultimately cancelled and refunds have been issued to ticket holders by Ticketmaster and Live Nation, the release said.

Sudden storm wallops Edmonton, soaks concertgoers
Thousands of people were forced to quickly leave a Post Malone concert at Edmonton’s Commonwealth Stadium because of a sudden, heavy rainstorm. The city was hit was more than 30 millimetres of rain in an hour, knocking out power and flooding some areas.
Some roads, facilities remain closed
Crews were still working Monday to reopen roadways, clear debris and assess damage, but City of Edmonton infrastructure has largely withstood the heavy rainfall this summer, the city said in its news release.
Fallen trees and flooding closed multiple roadways in Edmonton on Saturday and into Sunday, including Yellowhead Trail, Whitemud Drive and Groat Road. These roads are now open, the city said.
Connors Road reopened on Sunday, but Edmonton police said Monday afternoon the roadway is closed again due to flooding near 98th Avenue.
The storm is an example of how quickly road conditions can change during severe weather, an Epcor statement said.
“With thunderstorms continuing to be a feature of Edmonton’s summer, we encourage residents to avoid flooded roadways and stay clear of underpasses during heavy rain events.”
The utility provider also recommend Edmontonians consider planning alternate routes or delaying travel until conditions improve in cases of extreme weather.

Edmonton has had torrential rain and storms the last few weeks, but what do the numbers say about this summer and what’s in store for the rest of the season? Colin Fong is a meteorologist with Environment and Climate Change Canada.
The 130th Avenue and 107th Street intersection remains closed, while 178th Street’s ramp to Whitemud Drive has been reduced to one lane until repairs are complete, according to the city.
Many city recreation facilities and attractions are closed due to the storm, including:
- Peter Hemingway Aquatic Centre at Coronation Park Sports and Recreation Centre
- The main pool, hot tub and sauna at Grand Trunk Fitness and Leisure Centre
- The Indigenous Peoples Experience at Fort Edmonton Park.
The city said it’s monitoring trail conditions in the river valley, and asked residents to exercise caution in the area.
“The North Saskatchewan River is powerful and unpredictable. Higher water levels, swift currents, submerged debris and unstable riverbanks can create dangerous conditions,” the release said, adding that if water rises to unsafe levels, the city will post closure signs and provide updated trail conditions online.

Severe thunderstorm soaks Edmonton, cancels concert
A Post Malone concert in Edmonton was cut short Saturday night, when a severe thunderstorm swept into the city. As CBC’s Sam Brooks reports, Edmontonians are once again cleaning up debris and pumping out flood water after another summer storm.
What does this rain mean for the future?
Repeated and consecutive rain events are putting undue strain on Edmonton’s stormwater and power systems, Epcor said in a statement, noting the group is investing $1.6 billion in flood mitigation infrastructure over 20 years.
“While the system is designed to manage typical rainfall at a city-wide level, we know extreme and prolonged rainfall can challenge or temporarily exceed capacity in localized areas,” the statement said.
“Saturated ground conditions can also affect the system’s performance, as more water enters the system when it would normally seep into the ground.”
The city said June’s storms have prompted it to apply for the province’s Hazard Assistance and Resilience Program (HARP), which asks Alberta to reimburse municipalities for up to 90 per cent of eligible disaster costs.
June’s storms caused roughly $26 million in uninsurable loss and damage, the city said. According to the Insurance Bureau of Canada, as of mid-July, Edmonton storms have caused $230M in insured damages since May.
“The city continues to assess the impacts from July storms and will submit further HARP applications by the end of August,” it said. “Where possible, the city has leveraged existing warranties and insurance.”
