It can vary widely. The rating of a tornado is not based on the quantity of damage done by a tornado, but the severity. In other words, its not how many things are damaged; it's how badly damaged they are. In F3 damage, a well constructed house will be destroyed, losing its roof as well as exterior and possibly some interior walls, though at least something is left standing. A well-built house that has been completely leveled is generally considered F4 damage, though for poorly built houses an F3 rating is often appropriate. Depending on where it occurs an F3 tornado may destroy hundreds of houses, just one, or none at all. Tornado ratings do not just use house damage. Some tornadoes have been rated based on damage to trees and power lines.
An F3 tornado will destroy most trees and leave most houses partially destroyed. An F5 tornado will completely destroy most structures, debark, trees, and send them airborne.
An F3 tornado is pretty destructive. In the areas hit hardest well built houses will have their roofs removed and multiple, possibly most walls collapsed. Weaker structures will be completely destroyed. In such a tornado cars are tossed an trains derailed.
F3 is a category on the Fujita scale which rates tornadoes From F0 to F5 based on the severity of the damage they do. An F3 is a strong tornado which can tear the roof and walls off most houses, uproot and even throw most trees, and throw trains.
The Fuijta Scale rates tornado from F0 to F5 based on the severity of the damage they cause. An F3 is a strong tornado that will cause severe and often irreparable damage to frame houses. A house that takes F3 damage will lose it roof and many, if not most of the walls will collapse. F3 tornadoes can obliterate trailers (though this is considered F2 damage), throw cars, and lift train cars. About 4% of tornadoes are rated F3.
Size is not the basis for rating tornadoes, nor is there any given size for a tornado of a particular rating. Ratings are instead based on the severity of the damage, rather than size. In an F3 tornado well-built houses will lose their roofs many and if not most of their walls while weaker structures may be completely destroyed and nearly all trees will be toppled. That said, F3 tornadoes tend to be on the large side, typically over 200 yards wide with some topping 1 mile. One EF3 tornado in 2007 was documented at over 2 miles wide.
The 1973 Brisbane tornado was an F3. A strong F3 tornado can lift trees into the air.
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.
Yes, an EF3 tornado can potentially cause significant damage to a brick house, including structural damage such as roof removal and exterior wall collapse. The severity of the damage would depend on various factors such as construction quality and tornado intensity.
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.
The worst tornado of 2005 was an F3 that killed 25 people in the town of Evansville, Indiana.
Note that the wind speeds provided are estimates and not to be taken at face value. F0: (gale tornado), 40-72 mph. Some roof tiles and siding stripped, tree limbs broken, signs damaged. Weak sheds and outbuildings may be destroyed. F1: (moderate tornado), 73-112 mph. Roofs of houses severely damaged. Poorly secured roofs may be removed. Trailer homes overturned. F2: (significant tornado), 113-157 mph. Roofs torn from well-built houses. Trailer homes completely destroyed. Large trees snapped. F3: (severe tornado), 158-206 mph. Roofs and walls torn from well-built houses, weaker houses may be completely leveled, most trees in a forest uprooted. F4: (devastating tornado), 207-261 mph. Well-built houses leveled and left as pile of debris. Poorly anchored houses blown off foundations. Trees debarked. F5: (incredible tornado), 261-318 mph. Well-built houses completely swept away, leaving bare foundations. Reinforced concrete structures destroyed.
