The Magic School Bus Inside a Hurricane is the seventh book in the original book series.


Ms. Frizzle is ready to conduct her students in the bus. This time, it's a trip into the clouds to gather facts about hurricanes--firsthand. When the bus transforms itself into a hot-air balloon (and later into a weather plane) to take a close look at one of the world's hurricane breeding grounds, the class, especially Arnold, realize this won't be an ordinary lesson in meteorology.
