The Storm Prediction Center has a brief description of the new Enhanced Fujita Scale.
Here's the full report submitted by the Wind Science and Engineering Center at Texas Tech University in PDF format.
A modification of the original Fujita Scale developed by "Dr. Tornado", T. Theodore Fujita of the University of Chicago.

New EF Scale: Old F-Scale: Typical Damage:

EF0 (65-85 mph) F0 (65-73 mph) Light damage: Peels surface off some roofs; some damage to gutters or siding; branches broken off trees; shallow-rooted trees pushed over.

EF1 (86-110 mph) F1 (73-112 mph) Moderate damage: Roofs severely stripped; mobile homes overturned or badly damaged; loss of exterior doors; windows and other glass broken.

EF2(111-135 mph) F2 (113-157 mph) Considerable damage: Roofs torn off well-constructed houses; foundations of frame homes shifted; mobile homes completely destroyed; large trees snapped or uprooted; light-object missiles generated; cars lifted off ground.

EF3 (136-165 mph) F3 (158-206 mph) Severe damage: Entire stories of well-constructed houses destroyed; severe damage to large buildings such as shopping malls; trains overturned; trees debarked; heavy cars lifted off the ground and thrown; structures with weak foundations blown away some distance.

EF4 (166-200 mph) F4 (207-260 mph) Devastating damage: Whole frame houses Well-constructed houses and whole frame houses completely leveled; cars thrown and small missiles generated.

EF5 (>200 mph) F5 (261-318 mph) Incredible damage: Strong frame houses leveled off foundations and swept away; automobile-sized missiles fly through the air in excess of 100 m (109 yd); high-rise buildings have significant structural deformation; incredible phenomena will occur.

EF No rating F6-F12 (319 and above) Inconceivable damage. Should a tornado with the maximum wind speed in excess of F5 occur, the extent and types of damage may not be conceived. A number of missiles such as iceboxes, water heaters, storage tanks, automoblies, etc.will create serious secondary damage on structures.
