Meaning: southeast 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; Revised King James Version, “Euraquilo,” i.e., northeast wind)

It is called a “tempestuous wind,” i.e., as literally rendered, a “typhonic wind,” or a typhoon. It is the modern Gregalia, Solano or Levanter (a strong easterly wind in the Mediterranean region). (Compare Jonah 1:4.)
