Kona storms (or Kona lows) are deep cyclones that form during the cool winter season of the central Pacific Ocean. A definition change in the term during the early 1970s makes categorization of the systems more complex, as many kona lows are extratropical cyclones, complete with their own weather fronts. Those across the northeast Pacific Ocean consider them subtropical cyclones as long as a weak surface circulation is present.<ref name="Hast"/> ''Kona'' is a Hawaiian term for ''leeward'', which explains the change in wind direction for the Hawaiian Islands from easterly to southerly when this type of cyclone is present.<ref>Ian Morrison and Steven Businger (2002).
