Medicine Hat, AB area tornado and downburst confirmed
NTP, in collaboration with Environment Canada, has confirmed an EF2 tornado and an EF1 downburst in the Medicine Hat area of Alberta. An NTP ground / drone survey collected key data, including a drone orthomosaic that provided a very high-resolution aerial image of the damage areas. This made it clear that the damage in the Cypress County area was tornadic, while the damage in the Redcliff area was due to a downburst. Please see the detailed summaries below.
