On May 3-4 of 1999 there was a very large tornado outbreak across the Great Plains. In those two days 114 tornadoes claimed 47 lives. The worst of these tornadoes was a mile wide F5 that tore through the Oklahoma City area, killing 36 people and causing $1 billion in damage. Mobile doppler radar measure winds in this tornado to 302 mph, the strongest ever recorded on earth.
Tornado Alley is not expected any time. It is a region, not an event. Tornadoes in Tornado Alley most often occur in the months of April, May, and June.
Tornadoes can occur in Tornado Alley during any month, but activity usually peaks in the month of May.
No, tornado alley is not moving east. It will always be a region of high tornado frequency. You may be referring to the relatively high frequency of tornadoes in the Deep South, which is called Dixie Alley. There are plenty of tornadoes here as well, just not quite as many as Tornado Alley in the Midwest.
Tornadoes can occur in Tornado Alley during any month, but activity usually peaks in the month of May.
The strongest winds ever recorded in a tornado (302 mph +/- 20) occurred in the Moore, Oklahoma F5 tornado of May 3, 1999.However, actual wind measurements from tornadoes are rare, so other tornadoes may have been stronger, but never had their winds measured.Another good candidate for the strongest tornado in Tornado Alley is the Jarrell, Texas tornado of May 27, 1997, which produced the most extreme tornado damage ever documented.
Tornado Alley covers an area of hundreds of thousands of square miles. It would be impossible to name all the places there. Additionally, the boundaries of Tornado Alley are not officially defined. Some areas may be included in Tornado Alley on one map, but not on another.
It is difficult to pick one that is actually the strongest. Tornado Alley has had a number of tornadoes rated F5 or EF5, but beyond that it is difficult to say whether one was stronger than another. The fastest winds directly measured in a tornado were 302 mph in the tornado that hit the Oklahoma City area on May 3, 1999. However, actual wind measurements from tornadoes are rare, so other tornadoes may have been stronger, including the Andover, Kansas tornado of April 26, 1991 and the Jarrell, Texas tornado of May 27, 1997.
The area gets 700-800 tornadoes each year, which averages to about 2 tornadoes each day. However, tornadoes do not hit Tornado Alley daily, but often occur in outbreaks. Also, tornado activity is much higher in spring and early summer than other times of year.
Living out your whole life in tornado alley, you still may or may not see a tornado in your life. The odds of being in a tornado are probably about 1/300. Over an entire life....maybe less.
The F5 tornado of 1999 May 3, 1999 does not have a name, nor does any tornado. It is often called the Oklahoma City tornado, the Moore tornado, or the Bridge Creek-Moore tornado in reference to the areas it hit.

Opinions may differ, but I'd say so.
