Abstract
  • The maps presented here describe a hypothetical but realistic tornado striking Regina, Saskatchewan on Tuesday, June 30, 2026. The scenario tornado reaches a maximum rating of EF4 on the Enhanced Fujita scale. It resembles the Regina Cyclone of Sunday, June 30, 1912. The scenario tornado has a similar path and damage swath. It spans approximately 400 metres wide as it passes from soutrh to north through downtown Regina. With a translational velocity of 17 m/sec (61 km/hr) and counterclockwise rotation, the tornado produces windspeeds reaching 91 m/sec (328 km/hr) on the right side of the track. The map is available here in electronic format as a compressed Keyhole Markup Language (kmz) file. It depicts the scenario windspeeds. The file also contains the track and images of first-hand observations from 1912. The windspeed map comports with the current state of the art in tornado climatology. Severe rain and hail could accompany such a tornado. These other outcomes are addressed elsewhere. Windspeed map colors reflect bands of 3-second peak gust velocity that align with the Enhanced Fujita (EF) scale. White means 28-38 m/s (EF0). Green means 38-50 m/s (EF1). Yellow reflects 50-61 m/s (EF2). Red means 61-74 m/s (EF3). Burnt (hex color #74021a) reflects 74-91 m/s (EF4-EF5).
