MMMMM
It was a big weekend for waterspout sightings on the Great Lakes. More than 25 of these whirling funnels made up of air and mist were seen snaking across our big lakes on Saturday and Sunday, according to the Toronto-based International Centre for Waterspout Research.

And more are expected to spin up today. In fact, conditions favorable for waterspout creation are expected to last through Tuesday - maybe even Wednesday - across the Great Lakes.

But these whirling waterspouts carry some potential for danger, especially if you are close by or on the water. So boaters and even swimmers should stay aware of their surroundings if waterspouts are in the forecast, the National Weather Service said.

If you see one? Move away from the waterspout's direction of travel at a 90-degree angle. And if you're in a boat and see one, it's best to head to the closest harbor until it dissipates.

"We have confirmed at least 25 waterspouts / funnels over the Great Lakes on Sunday, August 24," the research group said early today. "More reports being investigated. Waterspouts continuing through to Tuesday."
