40-73 mph 65 to 85mph on the enhanced fujita scale
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.
Yes. In fact about 60% of all tornadoes are rated F0.
There has never been an F6 tornado. F0 is the most common type.
at a speed of about 350 km/h
The last tornado recorded to have hit Alaska was an F0 on Popof Island on June 25, 2005.
F0
40-72 mph
Yes. Baltimore was hit by an F2 tornado in 1973, an F0 tornado in 1996, an EF1 tornado in 2010, and an EF0 tornado in 2013.
There is no particular size, as tornado ratings are based on the severity of the damage caused, not the size of the tornado. That said, F0 tornadoes are typically small. Most are less than 100 yards wide.
The enhanced Fujita scale shows winds for an EF0 (the weakest level) beginning at 65 mph, while the original scale starts F0 at 40 mph. However it is important to note that winds traveling at over 65 mph do not make a tornado. A tornado is defined as a violently rotating column of air extending from he base of a thunderstorm to the ground. Meaning that if the wind doesn't rotate and does not come from a thunderstorm then it is not a tornado, regardless of wind speed.
Yes. Newport, Arkansas was hit by an F0 tornado in 1992 and an F1 tornado in 1999.
Strong enough to cause damage. New estimates on the Enhanced Fujita scale place win speed estimates for an EF0 tornado at 65 to 85 mph. This can uproot trees, peel shingles, topple fences, and destroy some weak structures such as sheds. This is the weakest rating a tornado can receive.
