The motion of a cyclone, at least in the Northern Hemisphere, makes this part of the hurricane the side that gets the forward rotational motion. This same tropical cyclone is known as a typhoon in the western Pacific and a cyclone in the Indian Ocean.

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. If there is enough moisture, then it may condense, forming a cumulus cloud, the first step towards thunderstorm development. Sea breeze front thunderstorm lines can become strong enough to mask the location of an approaching cold front by evening. It is more common in the outer bands.
