Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
South-east billow, the name of the wind which blew in the Adriatic Gulf, and which struck the ship in which Paul was wrecked on the coast of Malta (Acts 27:14; R.V., "Euraquilo," i.e., north-east wind). It is called a "tempestuous wind," i.e., as literally rendered, a "typhonic wind," or a typhoon. It is the modern Gregalia or Levanter. (Comp. Jonah 1:4.)
