Anatomy of a Hurricane
spiral rainbands, the eye wall and the eye

The Eye:
A region 20-50 km in diameter found at the center where skies are often clear, winds are light, and the storm's lowest pressure readings are obtained.

Eye Wall:
A ring of cumulonimbus clouds that swirl around the eye. The heaviest precipitation and strongest winds are found here.

Spiral Rainbands:
Bands of heavy convective showers that spiral inward toward the storm's center.
