Clouds raced across the face of the world below me.

It was as if a cloud had raced across the sun.

Low clouds raced all along the southern bank of the river.

The wind began to build, clouds racing across the sky.

Here it was cold, with low clouds racing across the sky before a sharp wind.

Clouds raced low along the peaks to the north but didn't look threatening.

The cloud had raced ahead, and this first swell seemed to travel upon a sea of lead.

The funnel cloud had touched down and was racing toward them!

Clouds of a tropical rainy season raced across the sky.

Dark clouds were racing across the sky, and the wind was ice-cold.
