This loop of GOES-10 visible channel imagery shows the development of convection across southern Alberta on 14 July 2000. Rapid Scan Operations (RSO) were activated for GOES-10 that afternoon due to the potential of severe convection across Montana, so imagery is available at 5-minute intervals for much of this period. The Pine Lake (25 km southeast of Red Deer, station identifier CYQF) tornado occured from 00:45 to 01:15 UTC on 15 July (6:45 to 7:15 PM MDT on 14 July).
