 Last night, we showed you images of waterspouts on Lake Winnebogosius near Dear River. Tonight, those images of waterspouts have gone viral. Emergency management officials shared on Facebook that they received several reports of funnels yesterday associated with thunderstorms. Officials say there were no sirens or warnings issued for waterspouts because these funnels are considered weak and not tornadoes. The lake temperature was in the mid-70s and considerably warmer than the air above the lake, which is a contributing factor in the formation of waterspouts. Waterspouts are rare in Minnesota but can occur on chilly days in August and September, when the temperature of the lake versus the surrounding air temperature is more than a 20 degree difference.
