When the first hurricane emerges from the Atlantic Ocean or Gulf of Mexico this season, NOAA will use a new statistical model to help predict the start of the “eyewall replacement cycle,” a key indicator that a storm’s strength and size is about to change dramatically. This new tool adds to a suite of forecast products NOAA uses to warn coastal communities of imminent threats.

An eyewall is an organized band of clouds that immediately surround the center, or eye, of a hurricane. The most intense winds and rainfall occur near the eyewall. Within a hurricane, eyewall replacement cycles occur when a second concentric eyewall forms around the original and eventually overtakes it. This phenomenon especially happens in strong, long-lived hurricanes. >> More
