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 F0
F1, 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 F1
F2 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.

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.
