CALGARY, ALBERTA – June 12, 2026 – A severe hailstorm struck large portions of Alberta on Friday afternoon, June 12, 2026, causing significant damage to homes, vehicles, and crops. Environment Canada issued severe thunderstorm warnings across the province, indicating conditions favorable for large hail, strong winds, and heavy rain. The exact time of the most intense activity was between 2 p.m. and 5 p.m. Mountain Time, with impacts felt from Red Deer southward to the U.S. border.
The storm system, which tracked northeastward from central Alberta, brought golf-ball to tennis-ball-sized hail in many areas. Reports indicate extensive damage to property, with residents describing the scene as apocalyptic. The Alberta Emergency Management Agency has been monitoring the situation, with many municipalities expected to assess the full extent of the damage in the coming days. Official statements from the provincial government are anticipated.
Eyewitnesses reported hearing a “wall of sound” as the storm approached, followed by intense hammering on homes and vehicles. In Calgary, the storm caused widespread damage to property, with some reports of vehicles being battered and windows shattered. The Calgary Fire Department responded to numerous weather-related incidents. In rural areas, farmers are reporting significant crop losses due to the violent hail, with some potentially losing their entire harvest. Bruce Lowe of Ag Direct Hail Insurance noted that the volume of claims is unusually high for this early in the season.
This event follows a pattern of severe weather activity in the Prairies over the past week. In previous years, similar hailstorms have occurred in Alberta, with a notable event in June 2020 causing an estimated $250-500 million in damages. Experts have identified “Hail Valley,” an area south of Calgary to north of Red Deer, as particularly vulnerable during the summer months. The current storm system has been tracked moving northeastward from central Alberta.
As of Friday evening, cleanup efforts are beginning in the hardest-hit areas. Emergency services are on standby to assist with any ongoing issues. The full impact on infrastructure and property is still being assessed. The provincial government is expected to provide updates on disaster relief measures.
Government officials are urging residents to stay informed through official weather alerts and to check on neighbors and family members. The WeatherCAN app and local radio broadcasts are recommended sources for up-to-date information. Updates on investigations into the extent of the damage and potential relief efforts will be provided as they become available. The long-term implications for agriculture and property insurance in the region are being closely monitored.
Social Media Verification Status: Initial reports and videos circulating on social media platforms show significant hail damage. Verification of specific damage claims is ongoing.
