White squall

Sudden and violent windstorm at sea not accompanied by black clouds

A white squall is a sudden and violent windstorm at sea which is not accompanied by the black clouds generally characteristic of a squall. It manifests as a sudden increase in wind velocity in tropical and sub-tropical waters, and may be a microburst. The name refers to the white-capped waves and broken water, its meager warning to any unlucky seaman caught in its path. A white squall was allegedly behind the sinking of the brigantine Albatross on May 2, 1961 although, in fact, there were a number of traditional line squalls all around and a microburst was very unlikely. White squalls are rare at sea, but common on the Great Lakes of North America.
