eyewall
Hurricane's fierce core
The eyewall is the ring of towering thunderstorms surrounding the calm eye of a hurricane.
It contains the storm's most violent weather—the strongest winds, heaviest rainfall, and most intense updrafts.
The eyewall passed directly over the coast, bringing sustained winds of 150 miles per hour.
