I'm not sure what are feeder bands in a hurricane. The eye can grow or shrink in size, and double (concentric) eyewalls can form. [4] In an atmosphere with rich low level moisture and vertical wind shear,[5] narrow, convective rainbands known as squall lines form generally in the cyclone's warm sector, ahead of strong cold fronts associated with extratropical cyclones.

Usually with HUGE eyes (sometimes wider than the width of the surrounding ring of convection!). Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes. If the atmosphere is cold enough, these rainbands can yield heavy snow. Feeder bands can also be prolific tornado producers, especially if theyre on the right-hand side of the hurricane (more on that shortly). What are "feeder bands" in hurricanes and why do they occur?

Different programs have been studying these rainbands, including the Hurricane Rainband and Intensity Change Experiment. The fastest wind speed ever recorded comes from a hurricane gust. Changes in the structure of the eye and eyewall can cause changes in the wind speed, which is an indicator of the storm's intensity. Hurricane Andrew (1992), the second most devastating hurricane to hit the United States, next to Katrina in 2005, was a relatively small hurricane.
