<p>There is going to be a big storm and Jenny's son John loves storms. John counts the seconds between the thunder and the lightning. This tells him how far away the lightning is. Their dog, Patty, is scared because thunder is louder for dogs! Do you know how hailstones form? How to stay safe in a tornado? Why sandstorms are so dangerous? Or how big a hurricane can be? John does and now you can too!</p>
