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.
The wind caused by a tornado is its primary source of damage and destruction. Tornadoes are measured based on the Enhanced Fujita Scale. The weakest tornadoes, with wind speeds 65 to 85 mph, can rip branches off trees, uproot small trees and tear shingles off of houses. An EF 1 tornado has wind speeds ranging from 86 to 110 mph. These winds can tear up mobile homes and rooftops and cause exterior damage to houses. An EF 2 tornado's winds range from 111 to 135 mph. Winds of this consistency uproot mobile homes, tear roofs completely off houses and cause foundation damage to homes. A tornado with winds in the 136 to 165 range is classified as an EF3 tornado.
