Weather spotters report waterspout to Nat'l Weather Service Updated: Tuesday, July 15, 2014 WEST MICHIGAN (NEWSCHANNEL 3) - The unusual July weather is having quite an impact on Lake Michigan, with marine weather spotters reporting waterspouts to the National Weather Service.The reports flooded in Tuesday morning from St. Joseph to Saugatuck.The NWS has yet to confirm the reports.A viewer sent NewsChannel 3 a photo of one of the reported waterspouts off South Beach in South Haven. The funnel you see in the photo is caused by Tuesday morning’s unusual mix of temperatures. The air was unseasonably cold, with temperatures in the 50s. So when it came in contact with the warm lake surface, which hovered around 70 degrees, the air sucked upwards. In waterspouts, the surrounding air then rushes in to replace it and the spin-up continues.The NWS says more waterspouts are possible Tuesday through dinnertime. Keep in mind: while waterspouts are fascinating to see, they can be quite dangerous. If you do come across one, make sure to steer clear of it and seek safe harbor until it has passed.
