Felix 2007 after attaining category 5 status. You
can see a video of it, growing as it approaches Central America, at the
NOAA site,

Chris Mooney points out that Felix now holds the record for
shortest time for an Atlantic storm to intensify to Category 5
strength.
UPDATE (4 Sept. 2007): the video I linked to is updated in real time, so the impressive and rapid growth of Felix is no longer illustrated. Take my word for it, it was scary to see.
