Question

What does it signify if you see clouds moving rapidly in an unusual way?

Answer 1

high winds

Answer 2

In a severe thunderstorm high winds and possibly the presence of tornadoes.

Answer 3

That's a prime indicator that severe weather may be coming your way (thunderstorms, tornados, etc.).  Just remember that it's an INDICATOR -- it doesn't mean you need to take cover.

Answer 4

It signifies that it's windy above.

Answer 5

Winds are caused by pressure differences such as those on either side of a rapidly approaching cold front.  There are usually more fast winds on the cold side of the front than the warm side, this is caused by tighter pressure gradients on the cold side.

Answer 6

Strong high altitude winds. Frequently an indicator of storms approaching, but not always.
