Describe the thunderstorms that ravaged the Jackson's Island?

At about midnight, the three awake to a solemn silence that has gripped the island. The air grows cold, and soon, a drenching rain begins to pour down upon them. In the darkness, they scramble to shelter underneath their tent, cold, scared, and wet. The storm passes violently, with blinding conflagrations of lightening, harsh winds, and ear-splitting thunder. With their fire burned out and their shelter damaged to the point of uselessness, Tom, Joe, and Huck attempt to distract themselves by playing "Cowboys and Indians."
