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.
Level EF-0 Tornadoes. EF-0 tornadoes produce wind speeds between 65 and 85 miles per hour. For a traditional house of less than 5,000 square feet, these winds will cause the loss of some roofing material, gutters and vinyl siding. Mobile homes will suffer uplift of their one-piece metal roofs.
