That record is held by April 27, 2011 on which 207 tornadoes struck the U.S.
The greatest number of deadly tornadoes in the U.S. struck in 1974. That year there were 79 killer tornadoes in the U.S. which resulted in 366 deaths. The deadliest year for tornadoes, however, was 1925 with 794 people killed by tornadoes. 695 of these were from one tornado, the deadliest in U.S. history.
Tornadoes occur in many areas around the world by no region experiences more tornadoes than the central United States. No one really knows for sure how many there are in the US each year, but it is estimated that over 1,000 tornadoes occur each year in the US, although many go undetected and unreported.
About 25% of reocrded tornadoes take place outside the United States. However, the actual percentage is probably much higher. The United States is one of only a few countries that keeps detailed tornado records. As a result, there a likely hundreds, possibly thousands of tornadoes that occur every year outside the U.S. that are never recorded.
As of January 17, 2013 the last tornado in the U.S. was an EF1 near Poplarville, Mississippi on January 13. It was one of four weak tornadoes to occur in the southern U.s. that day.
Yes. Tornadoes occur every year. The 1920s was the deadliest decade for tornadoes in U.S. history. Among these is the Tri-State tornado, the deadliest tornado in U.S. history, which killed 695 people. In addition to this, there were several tornado outbreaks in 1920 and 1927 with death tolls over 200, with one death toll possibly approaching 400.
Most days Oklahoma does not get any tornadoes. However, Oklahoma usually has at least a few days each year with several tornadoes, and occasionally more. In some outbreaks Oklahoma has experienced more than 50 tornadoes in one day.
The U.S. averages about 1200 tornadoes per year which works out to an average of about 3.3 per day. It is far from an even distribution, though. First, tornadoes are far more common in spring and summer than in the winter and activity varies from year to year. Second, tornadoes often occur in outbreaks with major events sometimes producing several dozen tornadoes in a single day. Between outbreaks there can be periods of little to no tornado activity. The largest number of tornadoes observed in 24 hours is 208 set on April 27, 2011. Accurate global statistics are not available as many countries do not keep records of tornadoes.
The highest number of tornadoes Alabama has recorded in one years was 145. This record was set in 2011.
The highest number of tornadoes to have occurred in in one day was 207 on April 27, 2011. The whole outbreak lasting April 25-28 featured over 350 tornadoes, making it the largest ever recorded.

The record for the most tornadoes in one day is 358 confirmed tornadoes on April 27, 2011, in the United States. This outbreak occurred across multiple states in the southern and eastern U.S. and resulted in widespread devastation and loss of life.
The U.S. has between 1,200 and 1,300 tornadoes in an average year.
It is not known. In an average year there are about 1800 recored tornadoes worlwide, most of them in the United States. However, the actual number of tornadoes is certainly much higher. Most countries do not keep detailed records or conduct damage surveys, so most tornadoes, possibly a vast majority, are never recorded, especially in sparsely populated areas.
It varies from one year to the next, but Virginia appears to average about 20 tornadoes per year.
Since official record keeping began in 1950 Kansas has had over 3,700 recorded tornadoes. Overall the number actual is much higher though as many of the weak tornadoes in the earlier period were never recorded. A figure closer to 6,000 is probably more accurate.
Alabama averages about 45 tornadoes per year, but it varies from one year to the next.
The number can vary considerably from one year to the next, but the average is about 39 tornadoes per year.
