In the apocalypse, chaotic weather is one of humanity's enemies.
A clear and sunny day could suddenly turn into a torrential downpour, and by the next day, snowflakes might even be drifting from the sky.
Without a stable base, anyone is insignificant in the face of such weather. Awakened professionals might fare better, but ordinary people feel miserable, shivering so much that their teeth chatter, and they might even freeze to death.
Nature is ruthless.
This weather will only gradually improve after a year. It is a catastrophe brought by the apocalypse, similar to some energy storms. In this disaster, the mortality rate of the elderly and children reached 80%.
This is a brutal reality.
Vulnerable people, even if they escape being devoured by monsters, still succumb to the weather. Hunger, snowstorms, and drought plague the surviving humans.
