The Jedi can sense local meteorological and geological conditions and predict imminent disasters, such as earthquakes, volcanic eruptions, floods, landslides, avalanches, caveins, tornadoes, hurricanes (hurricanes can also can be predicted with weather sense), etc. By opening his or her senses to the environment, the Jedi can predict these disturbances, much as animals can seemingly sense an earthquake hours or even days before it happens. Like weather sense, this power does not lend itself to quick predictions. It customarily takes weeks for a Jedi to get to know local weather patterns and topography. The prediction is effective for 12 hours. The difficulty increases by one level for each additional 12-hour period by which the Jedi wishes to extend the prediction.
