March through August
About 1% of thunderstorms produce tornadoes.
Tornadoes do NOT only occur at 3pm or 9pm. Tornadoes can occur at any time of the day or night, but MOST tornadoes come in late afternoon or evening at the hottest times of the day.
75 percent of recorded tornadoes happen in the U.S. The U.S. probably has a much smaller percentage of the world's actual tornado count. This is because the U.S. keeps detailed records on the tornadoes that occur within its borders. Many other countries do not keep such records, and often only the most significant tornadoes are reported.
Tornadoes do not occur in polar regions, such as Antarctica, or in extreme desert areas such as the Atacama.
Yes. Tornadoes can occur anywhere in the US.
Tornadoes usually strike in the afternoon or evening. Over 80 percent of tornadoes occur between 12:00 p.m. and 12:00 a.m.
About 1% of thunderstorms produce tornadoes.
No, about 1% percent of tornadoes are rated as violent EF4 or EF5). About 75-80% of tornadoes are rated as weak (EF0 or EF1).
Official statistics say 75-80% of tornadoes occur in the U.S. This is very misleading, however, as most countries do not keep detailed records of their tornadoes. The vast majority of tornadoes outside the U.S. are never documented. So, the real percentage is not known.
It is estimated that 3 out of every 4 tornadoes occur in the United States, 80% of those occur on the Great Plains, also known as Tornado Alley.
The strongest tornadoes occur the least often. Only a few percent of tornadoes are rated EF3 or higher. Less than 1 in a thousand receive an EF5 rating.
75 percent of recorded tornadoes occur in the U.S. However, this is misleading as unlike the U.S. many countries do not keep records, resulting in tornado numbers outside the U.S. that are unrealistically low.
Tornadoes can occur just about anywhere severe thunderstorms can but are very rare in a lot of places.
95% of all tornadoes in the US occur in an area known as Tornado Alley, which includes parts of Texas, Oklahoma, Kansas, and Nebraska. Additionally, tornadoes can also occur in other regions of the US, such as the Southeast and Midwest.
In the small intestine
Most tornadoes occur in spring.
Official records indicate 75 to 80 percent of the world's tornadoes occur in the U.S. This statistic, however, is highly inaccurate as it only counts recorded tornadoes. The U.S. portion of the world's tornadoes is probably much smaller. The United States is a wealthy nation with plenty of resources to track down almost every tornado that touches down within its borders, including minor ones that do no more than topple a few trees. Many other countries do not conduct tornado surveys, resulting an many, if not most tornadoes going unrecorded. Tornadoes that touch down in very remote areas are also unlikely to be recorded.
