By imaging a storm as often as every 30 seconds, these satellites help forecasters more easily discern the movement of cloud features and provide greater confidence in estimating the center of the storm. GOES-16 and GOES-18 also provide a detailed look at the storm properties of a hurricane, including cloud top cooling, central pressure, and convective structure...This information is critical to estimating a storm’s intensity.
