chubasco
choo-BAS-koh
A violent squall with thunder and lightning, especially off the Pacific coast of Central America and Mexico. Chubascos arrive suddenly, turn the sea white, and pass just as fast — leaving the air washed clean and the ocean unsettled.
Etymology
Spanish: chubasco, squall, downpour. Possibly from Portuguese chuva (rain), from Latin pluvia.
