What was the wind speed of the tornado that hit Delhi Louisiana in 1971?

There is no way of knowing for certain as the means of measuring tornado wind speeds had not been invented yet in 1971. Based on damage the tornado was rated F5, which would put estimated winds in the range of 261-318 mph.

Why is the EF5 the strongest tornado?
This goes back to when the original Fujita or "F" scale developed in 1971. Back then Dr. Fujita developed a means of rating the strength of tornado, in this scale he described 6 basic damage levels (mostly based on damage to houses) from F0 to F5 with accompanying wind speed ranges. Simplified, they are as follows F0: minor roof and siding damage F1: severe roof damage F2: roof torn off F3: walls collapse F4: entire house collapses F5: entire house blown away Fujita also defined wind values for levels F6 to F12 to correlate wind speed with mach number, but since F5 (complete destruction) is the most severe damage possible these levels were never used, leaving F5 as the highest real rating. The reason the damage levels were defined as F0 to F5 rather than F1 to F6 was likely for two reasons: F0 winds were set at below hurricane force, and our number system is partially based on 5. When the Enhanced Fujita scale was put into effect in 2007 it carried over essentially the same ratings and damage levels with adjusted wind ranges. Since the F6 and higher ratings were never used, they were simply dropped without a mention. So if you find that a tornado has been officially rated EF5, it means that well-built structures were completely obliterated.
What are the scales used for measuring tornadoes strength?
There are three scales for measuring tornado strength, all of which use damage to estimate wind speed. The first and most famous is the Fujita scale, developed in 1971. This scale rates tornadoes from F0 at the weakest to F5 at the strongest. Most countries that take the time to rate their tornadoes use this scale. The next scale to be creates is the TORRO scale, developed in 1975 which runs from T0 at the weakest to T11 at the strongest. There are two TORRO categories for every Fujita category, for example a T0 or T1 tornado is equivalent to an F0 while a T10 or T11 is equivalent to an F5. This scale is used in only a few European nations. Finally there is the Enhanced Fujita scale developed in 2007.It runs from EF0 to EF5. This scale was derived from the Fujita scale and provides more accurate wind speed estimates than the original scale, particularly where the original wind estimates for F3 and stronger tornadoes were far too high. Currently this scale is only used in the United States, though Canada plans to adopt the scale in 2013. All U.S. tornadoes prior to February of 2007 and all Canadian tornadoes prior to 2013 retain their original Fujita ratings.
Why did Dennis Gabor win The Nobel Prize in Physics in 1971?
The Nobel Prize in Physics 1971 was awarded to Dennis Gabor for his invention and development of the holographic method.
How much does a 1971 silver dollar weigh?
No Eisenhower Dollars that were issued for circulation (1971-1978) contain silver. For 1971 the San Francisco Mint did strike proof collectors coins in 40% silver, the weight is 24.59 grams. The regular issue coins from the Denver & Philadelphia Mints weigh 22.68 grams.
How much does a 1971 Kennedy half weigh?
Modern copper clad Kennedy half dollars dated 1971 or later weigh 11.34 grams, though the weight may be slightly less if the coin is worn.
What is strongest Tornado to ever hit Louisiana?
On official records since 1950 the strongest tornado in Louisiana history was the F5 that hit Delhi, LA on February 21, 1971. Other tornadoes before 1971 may also have been F5.
How wide and long was the F5 tornado in Delhi Louisiana?
The Delhi, Louisiana tornado of 1971 had an average path width of 600 yards and is officially listed with a path length of 110 miles. However, some experts believe that the path was not this long. Some evidence suggests that the 110-mile track is not that of a single tornado, but of two tornadoes, with the second one forming as the first dissipated.
How many people were hurt or killed during the strongest tornado ever to hit Louisiana?
Since record keeping began in 1950 the strongest tornado to hit Louisiana, an F5 in the Delhi area on February 21, 1971 killed 47 and injured 510. However, only 11 of the deaths and 18 of the injuries were in Louisiana. The rest were in Mississippi, as the tornado crossed the state line. Other tornadoes prior to 1950 may have been stronger in Louisiana, but accurate records do not exist for that time.
When was the last tornado in Seattle?
The last tornado to hit Seattle was in 1971.
When did Tetsuya Theodore Fujita create the tornado ratings?
He created the Fujita Scale in 1971, using the Lubbock tornado of 1970 as a model.
When was Ralph Lister born?
Ralph Lister was born on April 30, 1971, in New Delhi, India.
Where was Bobby Jindal born?
Baton Rouge, Louisiana on June 10th, 1971.
How was tornado measured in the olden days?
Before the development of the Fujita scale in 1971 there was no rating system for tornadoes. All ratings of pre-1971 tornadoes are retrospective.
What year did Theodore Fujita develop the Fujita Tornado scale?
Fujita released the scale in 1971, but much of the development was based on a detailed survey of the Lubbock, Texas tornado of 1970.
