The 5 percent tornado probability from the SPC qualify for tornado watch issuance,
A 2 percent tornado probability typically means that isolated and probably weak tornadoes are possible.
This qualifies as a high-risk outlook. A 30 percent tornado probability typically means that the Storm Prediction Center anticipates a major tornado outbreak with the potential for multiple long-track and violent tornadoes.
This qualifies as a moderate risk outlook. A 15 percent tornado probability outook can have a variable meanin due to uncertainty inherent in such forecasts. However, they may often predict moderate tornado outbreaks and sometimes major outbreaks. In such cases strong tornadoes are not uncommon and there is sometimes potential for violent tornadoes. As with other outlooks, some systems are far less severe than anticipated.
The probability of a tornado hitting Kansas is 100%. Dozens of tornadoes occur in Kansas every year.
This is a high-risk outlook. A 60 percent tornado outlook would mean that the SPC anticipates an extremely intense tornado outbreak with multiple violent tornadoes. Only one such outlook has been issued. It was on April 7, 2006. The event was far less severe than anticipated.
A meteorologist would be someone who would qualify someone to be a tornado chaser. Tornado chasing is such a dangerous task to be in. It can be scary but a lot of people have been qualified.
The Weather Channel has a system of assessing tornado probability. Tornado condition 1 means there is approximately a 10% or 1 in 10 chance of a tornado occurring within 50 miles.
It can vary considerably as the is a fair degree of uncertainty. Usually it will mean a few scattered and mostly weak tornado will occur. Tornadoes stronger than EF2 are probably unlikely, though there are exceptions. This qualifies as a slight risk outlook.
A hatched area for tornadoes means that there is an estimated 10% or greater chance of a significant (EF2 or stronger) tornado within 25 miles of any point. You cannot have a 10% chance of a significant tornado if the probability of tornadoes overall is less than 10%.
This qualifies as a high-risk outlook. Such an outlook generally means that the SPC anticipates a major tornado outbreak with the potential for multiple long-tracked and violent tornadoes. Since the SPC started publishing outlooks online in 2003, only four days have featured 45% or greater tornado outlooks.
For the majority of the world's population it is 0. For a few people it is greater than 0 but even so, the overall probability is negligible.
Depends on what town you're talking about. You first have to determine the chance of your town getting hit ONCE by a tornado. Oklahoma City has a much higher risk of getting hit by a tornado than Los Angeles, CA...So therefore the risk of Oklahoma City getting struck by 2 tornadoes would be much higher than Los Angeles.
