Fetid was a child of the Latin word fetidus, and dates back to the early 15th century, as does its cousin (now in disuse), fetor. Reek, which originally was a verb meaning âto smoke,â took on the connotation of âto smell badâ in the 17th century.
A F4 tornado has a maximum speed of 260mph (418 kph). However it should be noted that the wind estimates of the original Fujita scale, which were meant to correlate with damage levels, have been found to be inaccurate. on the new Enhance Fujita scale the top estimated wind speed for an EF4 tornado is 200 mph.
It is considered an F5, though tornadoes were not ranked on any scale in that era. It holds records for longest path length at 219 mi (352 km), longest duration at about 3.5 hours, and fastest forward speed for a significant tornado at 73 mph (117 km/h) anywhere on Earth.
