Six more Prairie tornadoes for 2025
The NTP has confirmed six additional Prairie tornadoes with ratings ranging from EF2 to EF0-Default. Four of these are based on AI-assisted satellite review of forest areas in AB and SK, while two of these (plus an update of an existing tornado) in AB are based on reports from Riley Weekes (@RJTornado).
Details are provided in the event summaries below, along with a regional map. The tornadoes can be plotted on a map using the NTP Dashboard here.
