EAS Addon for ProtoManly's Weather Mod

by idot.__

With the EAS Block and Transmitter placed in a world, players receive Emergency Alert System warnings for storms, and the EAS Addon adds that layer to ProtoManly's Weather.

ForgeNeoForgeClient and serverCC0 1.0 Universal1.20.1 – 1.21.1

What it does

The EAS Addon mod adds an EAS Block and a Transmitter that detect storms and issue warnings to nearby players. The block works only when ProtoManly's Weather is installed alongside it, and the Tom TTS voice used for spoken alerts is fetched from an online API. A Radar block placed directly next to the EAS Block can receive polygons on radar.

Each EAS Block is claimed by the player who places it, and that owner can grant or revoke use for other players. The owner and server operators can issue warnings by right-clicking the block, or open a permissions screen by shift-clicking to change who may use it. Warnings can be issued automatically, manually or both, depending on the warngen settings in the configuration menu, and a manual option has to be switched on there first.

The mod is published for Forge and NeoForge for game versions 1.20.1 and 1.21.1, under the CC0 1.0 Universal license, which places the mod in the public domain and makes it not open source. It runs on client and server, so the server and every player need it, and the latest files are dated 2026-05-03 for Forge and 2026-08-02 for NeoForge.

Key features

  1. Warning transmissions

    The EAS Block and Transmitter send Emergency Alert System tones and warning text to players for detected storms.

  2. Damage-based tornado grading

    Tornadoes are graded by the damage they cause rather than by wind speed, using a Damage Surveyor and survey sessions.

  3. Towns and counties

    Towns and counties mimic real-life places and appear in warning text, with commands to manage them.

  4. SPC Station outlooks

    A town set as an NWS office can issue watches and outlooks for the day, and towns set under it join those watches.
