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.
A hurricane with maximum sustained wind speeds exceeding 249 km/h is referred to as Category 5. A wind gust of 318 mph was measured by Doppler radar during a tornado in Moore, Oklahoma, in 1999. However, Doppler records are not considered official.
