"Nether Weather" is an addition to Minecraft that aims to make the Nether feel more like a real place by introducing 3 new weather types to it. You will now encounter lavafalls, storms and heatblasts (which replace storms in the Nether Wastes).
SereneSeason Plus (formerly Extended Fix) enhances seasonal immersion with sub season based day/night speed and improved snow piling/melting logic, delivering smoother and more natural seasonal block behavior.
