There are several levels of alert in the early warning system. First there are severe weather outlooks by the Storm Prediction Center. These assess the general risk of severe weather across the U.S., usually up to 2 days out. However, sometimes outlooks may extend to 8 days out. These forecasts are based on computer weather models.
The next level is a tornado watch. A tornado watch is issued for a region of conditions over the next few hours will favor the formation of tornadoes. These to are issued by the Storm Prediction Center based on analysis of general weather conditions.
Finally there is a tornado warning, which is issued. Tornado warnings, which are issued by local National Weather Service offices, are based on a more integrated approach. One of the first lines of defense is Doppler radar, which can detect rotation in a storm that may produce a tornado and can sometimes detect the signature of the tornado itself. This warning system also relies on eyewitness reports. People can call in to report funnel clouds, tornadoes and rotation that can sometimes escape radar detection. Additionally, Doppler radar cannot "see" if a tornado is on the ground, so eyewitness reports may be needed to verify that one has touched down.

Is there a way to prevent or warn of tornadoes?
There is no way to prevent tornadoes, but warning systems have been in place for decades.
When was Famine Early Warning Systems Network created?
Famine Early Warning Systems Network was created in 1986.
Are volcanoes systems?

What can we do to minimize the tornadoes impact on humans?
We can work on advanced warning systems and education so that people can get to safe places in time. We can also apply construction techniques that make it less likely that buildings will be severely damaged by tornadoes.
Which resource helps in preventing floods?
Trees and plants, dams, levees, proper drainage systems, and early warning systems help prevent floods.
Has a tornado been prevented?
It is not possible to prevent a tornado from forming. Tornadoes are natural weather phenomena that occur as a result of specific atmospheric conditions. However, scientists and meteorologists continuously work on improving tornado warning systems and forecasting techniques to help mitigate the potential impact and provide early warnings to communities in the affected areas.
Why are tornadoes the most dangerous natural disaster?
Tornadoes can strike quickly and sometimes without warning.
Why do scientists need to create a better warning system for tornadoes?
A better warning system will allow people to better prepare for an approaching tornado, meaning that fewer people will be killed or injured in tornadoes.
What types of pressure systems are associated with tornadoes?
As with virtually all stormy weather, tornadoes generally occur with low pressure systems.
Are tornadoes mostly likely in late summer and early?
Tornadoes are more likely to occur in early summer.
What is the differenc batween a warning and a watch?
In relation to tornadoes a watch means that general conditions are favorable for tornadoes to form. A tornado warning means that a tornado may be developing or is already occurring.
What is a tornado watch and a tornado warning?
A tornado watch is a watch that is watching out for tornadoes. A tornado warning is a warning That lets you know that a tornado is spotted.
