In what way is the weather important in this chapter?

In this particularly significant chapter, Ralph finally loses his leadership over the other boys, who succumb to Jack's increasing charisma and the opportunity he gives them to indulge their violent and childish interests. Golding underscores the tragedy of this shift in power with the violent storm that ravages the island, a storm for which the shortsighted Jack was not prepared. Just when Ralph's calm judgment and practicality is most needed, he lacks the authority to bring the boys to safety. The storm on the island serves as a reminder of the perils they face; while Ralph has built shelters for the boys and is prepared for this situation, Jack has focused simply on hunting and entertaining the boys, to their detriment. Golding again directs the reader's sympathy towards Ralph, whose concern remains for the good of the group.
