From SHIPS text products ( ftp://ftp.tpc.ncep.noaa.gov/atcf/stext/ ):

"** 2010 ATLANTIC RI INDEX AL072010       EARL 08/31/10  00 UTC **
( 30 KT OR MORE MAX WIND INCREASE IN NEXT 24 HR)"

And using either advisory data or best track data he did undego rapid intensification of 30 knots.

Using best track data:

8/29 18Z - 70 knots
8/30 18Z -  115 knots

45 knot change.

8/30 0Z - 80 knots
8/31 0Z -  115 knots

35 knot change.

Using advisory data:

8/29 5PM EDT - 75 knots
8/30 5PM EDT- 115 knots

40 knot change.

8/29 11PM EDT - 85 knots
8/30 11PM EDT- 115 knots

30 knot change.

As for rapid deepening:

"Rapid Deepening:
A decrease in the minimum sea-level pressure of a tropical cyclone of 1.75 mb/hr or 42 mb for 24 hours."
From: http://www.nhc.noaa.gov/aboutgloss.shtml

According to advisory data and best track data, no.

8/30 0Z - 972mb
8/31 0Z - 938mb

34mb change.

Advisory data is 971 mb and 938 mb.

33mb change.

According to vortex messages:

A. Time of Center Fix: 31st day of the month at 4:26:00Z
H. Minimum Sea Level Pressure: 933mb (27.55 inHg)

A. Time of Center Fix: 30th day of the month at 5:00:30Z
H. Minimum Sea Level Pressure: 969mb (28.61 inHg)

36mb change. Close. Impressive nonetheless.
