F3 and F4 refer to ratings on the Fujita scale, which measures the strength of a tornado based on the severity of the damage it causes. It has six categories ranging from F0 at the weakest, causing minor damage, to F5 at the strongest, causing total devastation.
F3 on the scale indicates a strong tornado that will partially or mostly destroy well-built houses, but leave some walls standing.
F4 indicates a violent tornado that will completely level well-built houses.

What does F-0-F-5 when a tornado is rated?
The Fujita Scale rates tornadoes from F0 to F5 based on the severity of the damage they do.F0 is the weakest but most common category. F0 damage includes missing shingles, broken tree limbs, trees with shallow roots uprooted, gutters taken down and some trailers overturned. About 55% of tornadoes are rated F0F1, the next lowest category, is also the second most common. F1 damage includes severely stripped house roofs, severely damaged or mostly destroyed trailers, collapse porches and roofs, and broken windows. About 25% of tornadoes are rated F1F2 is the beginning of what care called significant tornadoes. F2 damage includes roofs torn from frame houses, trailers completely demolished, and cars lifted. large amounts of debris may start to fly. About 15% of all tornadoes are rated F2.F3 is the third strongest and third least common category of tornado. F3 damage includes many or most of the walls in a well-built home collapsed, sometimes with just a few left standing. Most trees will be uprooted. About 4% of tornadoes are rated F3.F4 is the beginning of what are called violent tornadoes. F4 damage consisted of well-built houses completely leveled and left as piles of rubble and trees stripped of their bark. About 1% of tornadoes are rated F4.F5 is the strongest and rarest category on the Fujita scale classified as incredible. F5 damage consists of well-built houses being swept clean off their foundations. Sometimes houses may be carried or thrown large distances. Pavement may be peeled from roads. Less than 0.1% of tornadoes are rated F5.
Is a tornado more violent going clockwise or counter-clock wise?
That depends on where the tornado is. Generally, tornadoes in the northern hemisphere rotate counterclockwise while those in the southern hemisphere rotate clockwise. There are more violent tornadoes in the horthern hemisphere, but that is mostly due to the fact that portions of the United States have an almost perfect setup for producing them. A small percentage of tornadoes rotate in the opposite direction from what is normal. These are called anticyclonic tornadoes (normal tornadoes are cyclonic). Many anticyclonic tornadoes are satellite tornadoes, and are generally weaker than the parent tornado that spawned them. Only one anticyclonic tornado has ever recieved a violent (F4 or F5) rating on the Fujita scale. It was an F4 that hit West Bend, Wisconsin on April 4, 1981.
What is an F 3 mean?
Referring to "an F3" can mean a couple different things. It may refer to one of a number of plane models including the Panavia Tornado, a fighter jet used by the RAF. It may also refer to a level on the Fujita scale, a system of rating the severity of tornadoes. On this scale the weakest tornadoes are rated F0 while the strongest are rated F5. A rating of F3 indicates a strong tornado capable of leaving well-built houses mostly destroyed.
Do tornadoes have ratings and if so what are they?

Is an F3 tornado the deadliest tornado?
No. While F3 tornadoes can be deadly they are not the deadliest. F5 tornadoes are the most destructive and generally the deadliest. The highest death toll from an F3 tornado in the U.S. since 1950 was 25, compared with nine F4 and F5 tornadoes with death tolls upwards of 50 of which three (all F5 or EF5) killed more than 100 apiece.
