 Tropical Cyclone Vivienne formed from a tropical low that had moved westward across the Timor Sea.It intensified rapidly during the afternoon and night of 5 April 1994, reaching maximum intensity on 8 April when it was located 550 km to the north-northwest of Broome.Its development from here on was hampered by vertical wind shear and Vivienne moved on a generally west-southwest path parallel to, but well offshore from, the Western Australian coastline.
