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.
