Hurricane Iniki
The Central Pacific Hurricane Center (CPHC) failed to issue tropical cyclone warnings and watches for the hurricane well in advance. For several days prior to the disaster, the CPHC and the news media forecast Iniki to remain well south of the island chain, with the only effect being some high surf conditions.  Some of the standard international computer models were indicating a northward turn towards the populated Hawaiian Islands, but these were rejected by the CPHC forecasters.  CHPC Advisory #19 was issued at 11 AM local time on September 10, and suggested that a weakening Iniki would remain well to the south.  It was not until a special bulletin was issued by the CPHC at 6:30 PM on September 10 - less than 24 hours before landfall - that any warning was given to the public.
