Excerpt: There are a number of examples in scripture where God enacts judgment upon a nation. However, in all of them God is not subtle about it.

Second, the destruction tended to be pretty swift and thorough. Sodom and Gomorrah did not have time to panic.

Not quite sure I agree:

Revelation 6:3-4
When the Lamb opened the second seal, I heard the second living creature say, “Come!” Then another horse came out, a fiery red one. Its rider was given power to take peace from the earth and to make people kill each other. To him was given a large sword.

No pre-warning other than Scripture from what I can read. No angels, no prophets other than the persecuted church (Revelation 6:9-1). That in it self could be considered a warning I suppose. If so the saints have been crying to God and warning about coming judgement since pretty much the conception of the church.

Revelation 6:7-8
When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!” I looked, and there before me was a pale horse! Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth.
