A waterspout, which forms when cold air moves across the Great Lakes, creating temperature differences between the warm water and cold air, can last anywhere between two and 20 minutes. The intense, tunnel-shaped vortex cloud can move at speeds of 10 to 15 knots.

There are severe weather and flash flood warnings across the state.
