On the 21st of April, 1992 an unnamed sub-tropical storm formed in roughly the same area.  It dissipated three days later.

Dr. William Gray’s team at the University of Colorado recently issued their long-range hurricane outlook, and they are calling for an above average season; 16 named storms and 9 hurricanes.
