NASA sees tropical storm Damien form off Australia's Pilbara coast

The low-pressure area that formed off Australia's Kimberley coast and lingered there for a couple of days has moved west and developed into Tropical Cyclone Damien off the Pilbara coastline. NASA's Terra satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of the new tropical storm.  The Pilbara Coast is also known as the northwest coast of Western Australia.
