PMW advanced observatory
by takumingo
PMW advanced observatory adds weather instruments to the world, including a rain gauge, a wind radar and a flood warning system that reads from ProtoManly's Weather.
What it does
The mod adds a rain gauge that reports temperature, wind speed, humidity and the current weather, plus a wind radar for tracking storms over an area. Precipitation graphs and a snow accumulation chart show how conditions change over time. A lever sets the next flood warning and a siren block sounds it, and the redstone output can follow either a flood index or the actual water level.
The mod requires BlueMap and ProtoManly's Weather, which supplies the weather data the instruments read. Chunk Loaders is optional, and the author recommends it so that instruments keep working while their area is out of player range. A server running it needs every connecting player to have it too. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, under All rights reserved, so the code is not open source.
Key features
Rain gauge and wind radar
A rain gauge shows temperature, wind speed, humidity and current weather, and a wind radar tracks storms nearby.
Flood warning siren
A lever sets the next flood warning, a siren block sounds it, and redstone output can follow flood index or water level.
Squall and cyclone settings
Config options control cyclone maximum width, squall forward speed, spawn range and the maximum number of each.
Snow depth and precipitation graphs
Graphs track snow depth and precipitation, with fixes so the precipitation graph no longer jumps near the render distance boundary.

What the author says
Information In addition to the rain gauge, this mod adds temperature, wind speed, humidity, wind radar, and current weather information. You need Protomanly Weather version 0.16.4 ~ 0.17.0 or later to use this mod. We recommend installing chunk loaders when using this mod. This will prevent the precipitation graph…
