Tornado!

Rex Geyer is standing near the window in his house. He's watching a storm in the distance. The sky is getting dark. In the dark clouds, he sees a tornado. It's moving directly toward him. He needs to get out of the storm's path.¹ It's time to leave his house and drive away.

While Rex is driving away from the storm, another car is driving toward it. A storm chaser is driving this car. Most people run away from tornadoes. Storm chasers chase² them. When storm chasers hear about tornadoes, they try to get near them. Some storm chasers do this as a hobby. Others do it because they are scientists and engineers. It's part of their research. They use weather probes to study tornadoes. Weather probes measure the wind and give scientists important information about storms. Tornadoes are extremely powerful storms, so storm chasers have very dangerous jobs.
