Feeder Bands Lines or bands of low-level clouds that move (feed) into the updraft region of a thunderstorm, usually from the east through south (i.e., parallel to the inflow).

In thunderstorm development, they are the lines or bands of low-level clouds that move or feed into the updraft region of a thunderstorm. Produced by a cumulonimbus cloud, it is a microscale event of relatively short duration characterized by thunder, lightning, gusty surface winds, turbulence, hail, icing, precipitation, moderate to extreme up and downdrafts, and under the most severe conditions, tornadoes. Depending on sustained surface winds, the system is classified as a tropical disturbance, a tropical depression, a tropical storm, or a hurricane or typhoon. Air Force reconnaissance observations indicated that the eye of the hurricane had contracted to as small as 2 n mi (3.7 km) in diameter. A warm core low pressure system which develops over tropical, and sometimes subtropical, waters, and has an organized circulation. Rainfall beneath them is torrential.

In fact, if one were to travel between the outer edge of a hurricane to its center, one would normally progress from light rain and wind, to dry and weak breeze, then back to increasingly heavier rainfall and stronger wind, over and over again with each period of rainfall and wind being more intense and lasting longer. Conversely, the farther the hands are from the body the slower they spin. Maybe they are just feeder bands. Thats usually where the strongest sustained wind speeds and gusts will be found over the entire span of a hurricane.
