An F1 tornado can break windows, strip the surface from a roof and heavily damage a mobile home. Barns will likely be destroyed. Poorly secured roofs may be torn off.
F1 damage is generally describes as moderate. Typical F1 damage includes broken windows, severely stripped roofs, badly damaged or mostly destroyed trailers, and collapsed garages and porches.
In most cases an F5 tornado will be larger than an F1. However, tornado ratings are a measure of the strength of a tornado, not its size. F5 is the strongest category, and such tornadoes are usually very large, but a few have been fairly small. Conversely, F1 is the second lowest rating (F0 is the lowest) and such tornadoes are generally small, but some have been huge.
The stronger a tornado the more energy it takes and most storms do not have the energy to produce a tornado stronger than F1 or are not organized enough to focus that energy into a tornado. Additionally, tornado ratings are based on damage and some tornadoes stay in open fields, causing no damage. Such tornadoes are rated F0.
F1 winds speeds are 71-112 miles per hour.
No. An F0 tornado is simple a weak tornado, or one that does little to no damage. A gustnado is a vortex that resembles a tornado that forms in the outflow boundary of a severe thunderstorm. Gustnadoes can occasionally cause damage comparable to an F0 or F1 tornado, but they are not considered tornadoes.
Typical F1 tornado damage surfaces peeled from roofs, windows broken, garages and porches collapsed, trailers overturned or severely damage, and trees knocked down.
F1 damage is generally describes as moderate. Typical F1 damage includes broken windows, severely stripped roofs, badly damaged or mostly destroyed trailers, and collapsed garages and porches.
An F1 tornado will severely strip material from the roofs of most buildings. Trailers can be overturned and badly damage and some may be destroyed. Windows can break, garages and porches can collapse and windows can break.
In most cases an F5 tornado will be larger than an F1. However, tornado ratings are a measure of the strength of a tornado, not its size. F5 is the strongest category, and such tornadoes are usually very large, but a few have been fairly small. Conversely, F1 is the second lowest rating (F0 is the lowest) and such tornadoes are generally small, but some have been huge.
An F5 tornado does not form directly from an F1 tornado. Tornado intensity is determined by the Enhanced Fujita Scale based on wind speeds and damage. It is possible for a tornado to rapidly intensify due to various atmospheric conditions, leading to an increase in intensity from an F1 to an F5 tornado.
Typical damage from an F1 tornado includes badly damage roofs, overturned or partially destroyed trailers, and broken windows.
A tornado earns an F1 or EF1 rating if it causes moderate damage. This may include badly damaged roofs on houses, broken windows, snapped trees, and trailers overturned or partially destroyed.
Estimated wind speeds for an F1 tornado on the original Fujita Scale are 73-112 mph. These were found to be inaccurate, though, and were adjusted to 86-110 mph for an EF1 tornado.
An F1 tornado is considered weak, with wind speeds ranging from 73 to 112 mph. Damage caused by an F1 tornado can include broken tree branches, shingles blown off roofs, and overturned outdoor furniture. While it is not as destructive as stronger tornadoes, it can still pose a threat to people and property.
The stronger a tornado the more energy it takes and most storms do not have the energy to produce a tornado stronger than F1 or are not organized enough to focus that energy into a tornado. Additionally, tornado ratings are based on damage and some tornadoes stay in open fields, causing no damage. Such tornadoes are rated F0.
An F1 is a moderate tornado having wind speeds of 117-181 km/h (73-112 mph). It may cause moderate damage, peeling off roofing, pushing mobile homes off their foundations, and pushing moving automobiles off the road.
F1 tornadoes can kill, but they rarely do. So an F1 tornado is unlikely to kill you, but you should still take safety precautions to reduce your risk, especially since you can't tell how strong a tornado is before it hits.
