Wat-er weird sight! This is what a 'pneumonia front' looks like

Take a look at this weird sight captured over the Detroit River on the Canada-US border.

It's called a "pneumonia front", but don't worry - it doesn't give you pneumonia! It's the name of a rare weather event over the river.

It looks a bit like a waterspout or tornado, except that the water isn't spinning.

Actually, what the video shows is moisture from the river being pulled upwards, towards a cold cloud.
