Monday thunderstorm floods roads, halts traffic and transit across Edmonton
Severe thunderstorms caused significant flooding across Edmonton, forcing the closure of major road interchanges and disrupting transit services. The city is working to manage the impact on infrastructure and public facilities, including the Muttart Conservatory.
Why it matters
Extreme weather events are increasingly impacting urban infrastructure, highlighting the need for resilient city planning and emergency response.
Three waves of heavy rainfall doused the region Monday afternoon as a line of storm cells swept northeast across central Alberta.
Environment Canada said its meteorologists were tracking a cluster of severe thunderstorms capable of producing strong wind gusts, loonie- to ping pong ball-size hail and very heavy rain.
The first wave hit at 1 p.m. over south Edmonton and was moving northeast at 20-30 km/h. The second and third waves swept through over the ensuing hour and a half, dropping enough rain to turn roads into rivers and lakes.
Just across the river from the downtown core, a major interchange was shut down due to massive flooding that left the area one big lake.
The interchange of Connors Road, Scona Road and 98 Avenue was closed where the roads intersect to cross the Low Level and James MacDonald bridges.
