Description
Weather Flux
A tornado and severe weather mod for NeoForge 1.21.1, currently in active development. We are NOT affiliated with any other mod in any way.
About:
Weather Flux aims to bring genuine severe weather to Minecraft. This mods adds tornadoes that move across the terrain, rain and storm systems that feel dynamic instead of static, and full weather events that form and move throughout the world. There are plenty of tools and instruments that can be utlized to predict, track, and record tornados and other systems.

This is a passion project built from the ground up, and it is still early in development. Expect bugs, expect missing features, and expect things to change quickly as we keep building it out.
