Based on information gleaned from the NHC website. this historical chart shows the ~70mb pressure drop within the past 24 hours quite nicely, as well as the almost DOUBLING of the windspeed in 30 hours. Whats the fastest or most pronounced pressure drop on record?

In the Atlantic Basin, Hugo was the most rapidly intensifying storm on record, dropping 72mb in a 24 hour period. Rita's stretch is 59mb in a 24 hour period, but if you factor in the 1716(EDT) report, its 69mb in a 24hour+16 minute timeframe, coming awfully close. Lets hope we don't have a recordbreaker, and see an 892mb storm at 11pm(EDT) tonight. Beulah's 6 hour record is broken on a technicality at 6.4mb/hour.

Equates to a 40mb drop in 6 hours and 16 minutes.

Typhoon Forrest in September 1983 in the Northwest Pacific Ocean deepened by 100 mb (976 to 876 mb) in just under 24 hr (Roger Edson, personal communication). Estimated surface sustained winds increased a maximum of 15 m/s (30 kt, 35 mph) in 6 hr and 44 m/s (85 kt, 98 mph) in one day (from 33 to 77 m/s [65 to 150 kt, 75 to 173 mph]).

In the Atlantic Hurricane Gilbert went from 960 mb to 888 mb in a 24 hour period for a 3 mb/hr pressure drop. The winds went from 57 to 82 m/s (110 kt to 160 kt, 127 mph to 184 mph) in that 24 hour period. And Hurricane Beulah in 1967 underwent a 6.33 mb/hr drop over a six hour period.
