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.[1] 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.
White squalls are the culprits of many sea stories and have been blamed for a few tragedies. A white squall was the reported cause of the loss of the schooner Paul Pry off Cape Schanck, Australia, on September 3, 1841.[2] In May 1986, the Pride of Baltimore, a modern 137feet schooner, was reportedly struck by a white squall. The 121-ton vessel sank about 240miles north of Puerto Rico, casting the surviving crew members adrift for five days. The Toro, a Norwegian freighter, picked them up at 2:30 a.m. May 19, 1986. An eyewitness account described it as follows:
"A tremendous whistling sound suddenly roared through the rigging and a wall of wind hit us in the back. The Pride heeled over in a matter of seconds. The 70kn wind pushed a 20feet high wall of water into the starboard side. She sank in minutes."https://www.usatoday.com/weather/resources/askjack/waoceans.htm
