Answer to Question 1

ANSWER: Intense thunderstorms can be associated with floods and flash floodsfloods that develop rapidly with little or no advance warning. Such flooding often results when thunderstorms stall or move very slowly, causing heavy rainfall over a relatively small area. Flooding may also occur when thunderstorms move quickly, but keep passing over the same area.

Answer to Question 2

ANSWER: As the cloud builds well above the freezing level, the cloud particles grow larger. They also become heavier. Eventually, the rising air is no longer able to keep them suspended, and they begin to fall. While this phenomenon is taking place, drier air from around the cloud is being drawn into it in a process called entrainment. The entrainment of drier air causes some of the raindrops to evaporate, which chills the air. The air, now colder and heavier than the air around it, begins to descend as a downdraft. The downdraft may be enhanced as falling precipitation drags some of the air along with it.
