As a result, researchers can now investigate with greater accuracy how the rate of lightning strikes produced within a hurricane's eyewall is tied to the changing strength of that hurricane. A hurricane's eyewall is the inner heat-driven region of the storm that surrounds the "eye" where the most intense rainfall and most powerful winds occur. By monitoring the intensity of lightning near a hurricane's eye, scientists will be able to improve their forecasts of when a storm will unleash its harshest conditions.
