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 tornado of EF2 or moreâwinds of 111 to 165 miles per hourâcan destroy a structure. in four seconds. But only one in four tornadoes have wind speeds at 110 miles per hour or greater. That speed would be a major hurricane. Hurricanes can be hundreds of miles wide. And they can plow across thousands of miles for days.
