The cloud towered over an artificial cityscape made from industrial parts.

To the west, beyond the crater wall, black clouds towered.

When they flew through rain the clouds towered and overhung them, leaking blackness as if soaked in ink.

Before them towered great cumulonimbus clouds, many of them pouring avalanches of water oceanward.

The clouds that had been piling up all afternoon towered over the hills, grey with a menacing hint of yellow.

The swirling cloud was towering closer on Wilsa's right.

On sunny mornings cumulus clouds towered high over the sea, and Suldrun's blood seemed to quicken.

The clouds towered higher than the peaks of the Crest.

The rain had stopped, but clouds still towered in the sky-- soft gray mountains hiding the sun.
