Adam Clarke on Zephaniah 1:15

That day is a day of wrath - See Isa 22:5 (note); Jer 30:7 (note); Joe 2:2 (note), Joe 2:11 (note); Amo 5:18 (note); Zep 1:18 (note), and the notes there. From the fourteenth to the sixteenth verse inclusive there is a most beautiful amplification of the disasters that were coming on Jerusalem; the invasion, incursion, attack, carnage, confusion, horrible din occasioned by the sound of the trumpet, the cries of the people, and the shrieks and groans of the dying, are pointed out with great force and mighty effect.
