Severe weather summary: August 13, 2021
The past two weeks saw relatively few severe weather reports across the Prairies. For the first time this summer, Manitoba led with 28 reports, followed by Alberta with 24, and Saskatchewan last with 7. There were zero tornadoes reported again across the Prairies, which is also unusual for mid-summer.
One of the most significant events over the past two weeks occurred on August 9 in the Altona, MB area. A strong thunderstorm brought hail up to loonie size (2.7 cm / 1.1 in) to the region. Elsewhere, the largest hail report was walnut size (3.2 cm / 1.25 in) in Campsie, AB on August 3.
The climatological occurrence of severe weather continues to decline, as we are now well past the mid-July peak in such activity. However, severe weather remains common in August and many severe weather events have also occurred in September. We will continue to issue severe weather summaries until mid September.
