About this Mod

Information
In addition to the rain gauge, this mod adds temperature, wind speed, humidity, wind radar, and current weather information. You need Protomanly Weather to use this mod.

We recommend installing chunk loaders when using this mod. This will prevent the precipitation graph from jumping when you move near the render distance boundary.

1.3.6 or 1.2.10-1.20.1“Stable version”

Settings for “squall” and “cyclone” have been added. For cyclones, you can set the maximum width and maximum number.
For squalls, you can control the forward speed, spawn range, and maximum number.
Other changes, such as corrections to the snow depth graph

If you feel that the wind speeds during downpours are extreme or that the frequency of downpours is unusually high, I recommend adjusting the settings in PMW and My Addon, as they have dedicated options for this. Feel free to change them to your liking, as shown in the image below.
