A severe thunderstorm warning is in effect for parts of southern Alberta after an Alberta Emergency Alert for very large hail was issued on Monday evening.

Environment Canada says meteorologists are tracking a "very dangerous thunderstorm" capable of producing baseball-sized hail, strong wind gusts and heavy rain.

As of just after 9 p.m., the agency said the thunderstorm was located in Cheadle and Strathmore, Alta., and was heading to the east at 50 km/h.

An Alberta Emergency Alert was also originally issued at 7:57 p.m. on Monday. An 8:58 p.m. update to the alert noted that "extra care and attention" should be exercised in the areas of Blackie, Arrowhead, Milo, Vulcan, Carmangay and Lomond.

The emergency alert is in effect for the following areas:

"This is a dangerous and potentially life-threatening situation," reads Environment Canada's website.

"Extremely large hail can smash windows, destroy property and vehicles and cause life-threatening injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles."

The agency advises people to seek shelter whenever there is dangerous weather.

Calgary, originally part of the emergency alert, is now under a severe thunderstorm watch, according to Environment Canada's website.

In an email statement to CBC News sent Monday night, a spokesperson for the Calgary Airport Authority confirmed that a YYC Calgary International Airport terminal building had been damaged by hail and heavy rainfall.

"We are prioritizing the safety of all guests and staff and clearing the impacted area. We are currently assessing the damage and its impact to operations," reads the statement.
