LGG: "Alerta"

This story starts off with another extended description, this time of the apparent storm that is brewing. In the story, some royalist forces are stationed in a town. They rape a woman of the town, and later end up shooting her grandson. He runs off to the puperia, where the men of the village congregate, and his death stirs them up to go attack the royalist soldiers.

I think the storm clouds may serve a metaphorical purpose, though if so, it doesn't strike me as particularly subtle. There's an interesting bit where the weaver takes mate mixed with ashes and spreads them in a cross-shaped pattern in an attempt to influence the weather.
