From Sep 2 #ONstorms
- The NTP survey team documented an EF1 downburst in the Brodhagen area, and we now have evidence that tornadoes likely occurred in the Bamberg and Tavistock areas. The survey team will be back out investigating these and other damage areas tomorrow.

From Sep 3 #ONstorms
- It appears likely that the damage being reported in east Windsor is due to a tornado, and a survey team will visit tomorrow to confirm that and rate it.
