Based on data from the years 1950-2010 the top 10 states for tornadoes are.
In the past 10 years tornadoes at least 1402 people have been killed by tornadoes, including 1089 in the United States.
All 50 states have had tornadoes at some point. However, the greatest portion tornadoes, especially the stronger ones, occur on the central plains or in the Deep South. The top 10 states are:TexasKansasOklahomaFloridaNebraskaIowaIllinoisMissouriColoradoMississippi
Tornadoes occur most frequently in the United States but can occur in almost any place that gets thunderstorms. So most countries can get tornadoes, though they are rare in many places.
Most Tornadoes are weak. There is about a 69% chance that a Tornado will be an F0 or an F1, a 29% chance that a Tornado will be an F2 or an F3, and a 2% chance that a Tornado will be an F4 or an F5.
It is Texas that records the most tornadoes, with an average total of about 135 a year. Kansas has the most tornadoes per area (or per square mile). Recall that Texas has a lot more area than the other states in tornado alley.
The average tornado lasts about 10 minutes.
Generally not. While California is not at the bottom of the list, it experiences fewer tornadoes than most other states, averaging about 10 per year.
Weak tornadoes (EF0 and EF1) are by far the most common accounting for 89% of all tornadoes. Strong tornadoes (EF2 and EF3) are next, accounting for about 10% of tornadoes. Finally come violent (EF4 and EF5) tornadoes, which account for less than 1% of all tornadoes.
In the past 10 years tornadoes at least 1402 people have been killed by tornadoes, including 1089 in the United States.
It is not known at this point as of February 10. Worldwide records are not available as most countries do not keep records. In the United States there was a tornado outbreak on February 10, the extent of which is not yet known. It will take at least a few days to survey the damage and determine how many tornadoes there were. For events prior to the February 10 outbreak, there have been at least 66 confirmed tornadoes in the U.S.
How long a tornado lasts can vary widely. The average tornado lasts about 10 minutes. But tornadoes have been known to last as little as 10 seconds and as long as 3.5 hours. Not many tornadoes last more than 30 minutes. As to when they occur, tornadoes can form at any time of day or night, but are most common in the later afternoon and early evening. Similarly, tornadoes can occur at any time of year, but happen primarily in the spring.
Microbursts are more common. Most wind damage from thunderstorms comes from microbursts, and damaging wind is the most common type of severe weather report. By contrast only about 10% of severe thunderstorms produce tornadoes.
In total, 53 tornadoes formed in six states as a result of Katrina: 18 in Georgia, 10 in Mississippi, 10 in Alabama, and 5 each in Florida, Virginia, and Pennsylvania.
