Comments | Southern Alberta, August 4-5, 2015. A severe thunderstorm warning was in place for much of southern Alberta including tornado warnings. On August 4, a storm cell that produced low to moderate levels of hail formed in the Elbow valley and later moved into the northern regions of Calgary just as a second storm cell headed towards the southern region of the city. Both storm cells formed one large storm system that hit the Calgary area with severe hail. As the storm system move out of Calgary, the village of Standard was impacted by small hail and there were reports of a tornado sighting in Langdon that caused minimal damages. On August 05, the Calgary area was hit again by bad weather. In Calgary there was significant rainfall and wind gusts of up to 78 km/h. Flooding occurred in the city where it had rained up to 100 mm since the previous storm. Over all, both storms produced strong winds that caused damages to the roofs of apartment buildings and residential homes. Approximately 35,000 customers (105,000 individuals) lost power due to damaged power lines from fallen trees. Heavy rain and hail also caused flooding that submerged basements, vehicles and underpasses. |
