Extreme storms never cease to appeal. This visually tempting title defines and explains the storms people call twisters, gives examples of four particularly devastating ones in this country, describes tornado watchers at work, offers a hands-on activity and suggests precautions for tornado safety. Aimed at middle-grade readers, it includes step-by-step explanatory text, striking images and helpful graphics. The author introduces Ted Fujita and his tornado-measuring scale. She makes clear that tornado formation is still a scientific mystery. Much of the explanatory text is printed on a backdrop of remarkable photographs of storms and storm damage. Sidebars introduce extra information, vocabulary and short firsthand accounts of storm experiences with snapshots. Along with the clear explanations and visual interest, this volume and its companion, Carson’s Inside Hurricanes (ISBN: 978-1-4027-5880-5), are thoughtfully designed. The many fold-out and fold-up pages work. A symbolic arrow directs the reader; pages are numbered clearly and consecutively. Even the backmatter--bibliography, source notes, further resources and glossary--is on a fold-up page. Maps show storm locations in this country and around the world. Impressive.
