The Lord prophesied -
"For behold, and lo, vengeance cometh speedily upon the ungodly as the whirlwind; and who shall escape it?
23 The Lord’s scourge shall pass over by night and by day, and the report thereof shall vex all people; yea, it shall not be stayed until the Lord come;" (Doctrine and Covenants 97:22–23)
In my mind, verse 23 suggests the scourge will increase until He comes.
