How early can tornadoes be predicted?
In many cases the weather service can provide warnings with better than 10 minutes lead time. However, the likelihood of correctly detecting a tornado depends on a number of factors such as distance to the tornado from the radar, the type and orientation of the funnel or tornado, and whether there are any obstacles preventing radar detection. Doppler radar has provided a key tool for forecasters but efforts are being made to further increase warning lead time and detection accuracy.
