A massive sinkhole measuring 12x12 feet and over 10 meters deep has formed near the intersection of 130 Avenue and 107 Street in Edmonton's Lauderdale neighborhood following intense weekend thunderstorms.

The storm systems, with wind gusts up to 60 km/h and quarter-sized hail, caused widespread damage including downed trees, flooded streets, and structural damage.EPCOR crews are working to stabilize the roadway and repair the sinkhole, which is separate from recent flood-mitigation upgrades.The city has reopened several roads but maintains closures on 130 Avenue and 107 Street.Additional challenges include flooded recreation centers and ongoing cleanup efforts.

City officials warn that Edmonton's drainage system, while designed for heavy rain, can temporarily exceed capacity during extreme weather events.Temporary debris disposal sites and extended Eco station hours are in place to assist residents with storm-related cleanup.
