Expanded Weather2 Dynamics
by RAH Studio
Expanded Weather2 Dynamics is an addon for the Weather2 storm system that adds tornado behavior, radar and alert tools, and survival storm damage on Forge and NeoForge.
What it does
The addon keeps the core Weather2 weather system and extends its severe storms. Tornadoes gain deeper dynamics such as width changes, bending, merging of satellite tornadoes and anti-cyclonic support. Radar behavior responds to circulation, and the mod includes a radar block, an anemometer and a weather alert siren. Server-side behavior, visuals and blocks are added alongside the existing storm features.
Storm tools cover SPC-style risk outlooks, fictional TOR and SVR alerts and automatic fictional EF-style damage surveys after a tornado passes. Tree debarking, ground scouring and cycloidal marks are part of the storm damage. Multiplayer behavior is server-authoritative, and most intensity settings can be changed in the configuration file. Weather2 and CoroUtil must be installed for the mod to run, and Weather Storms & Tornadoes is required as well.
Key features
