7. Weather and Tornadoes
The weather effects in Minecraft are pretty tame, with the occasional thunderstorm being the only real worry. The Weather and Tornadoes mod changes all that. From raging storms complete with gusts of wind sending your arrows off course to full blown tornadoes ripping the dirt up from under you this mod adds some seriously dangerous meteorological phenomena to the game. Its not just twisters and typhoons however; this mod also adds new rain textures and a number of new sound and particle effects, making the in-game weather far more realistic and sometimes pretty damn scary. There's not a lot you can do if a tornado rolls around but you can build yourself an early warning system using the two new blocks included with the mod: A tornado detector and a tornado siren, allowing you to batten down the hatches and seek refuge underground while the storm rages overhead. If you fancy yourself an amateur storm chaser then Weather and Tornadoes is one mod you'll definitely want to pick up. You can find the mod and full installation instructions
