Outer bands: The rings of thunderstorms farthest away from the eye of a hurricane or tropical storm that are the first to come ashore during landfall. [18] Within this method, the extent of spiral banding and difference in temperature between the eye and eyewall is used to assign a maximum sustained wind and a central pressure. Convective rainbands can form parallel to terrain on its windward side, due to lee waves triggered by hills just upstream of the cloud's formation.
