The characteristics of a hurricane are powerful winds, driving rain, and raging seas. Although a storm must have winds blowing at least 74 miles an hour to be classified as a hurricane, it is not unusual to have winds above one hundred and fifty miles per hour in a major hurricane. The entire storm system can be five hundred miles in diameter, with lines of clouds that spiral toward a center called the "eye." Within the eye itself, which is about 15 miles across, the air is actually calm and cloudless. But this eye is enclosed by a towering wall of thick clouds where the storm's heaviest rains and highest winds are found.
