|New EF Scale:
|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.
||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.
