Local Forecasts
The best resources for keeping tabs on a tornado threat are NWS forecasts. The NWS Storm Prediction Center (www.spc.noaa.gov) analyzes the daily potential for tornadoes and severe thunderstorms. When conditions favor multiple tornadoes, the SPC will issue tornado watches for inland portions of tropical cyclones. The SPC is also responsible for severe weather outlooks and other forecast products that will discuss the potential for tornadoes. Local WFOs will also issue tornado watches and warnings based on local data and observations.
- Tornado Watch: A watch is issued to alert the public that severe thunderstorms and tornadoes are possible during the next few hours, in and around the watch area. A tornado watch does not mean that tornadoes will occur, only that they are possible.
- Tornado Warning: A warning means that a tornado has been sighted by storm spotters or has been indicated by radar. These warnings are issued with information concerning where the tornado is presently located and what communities are in the anticipated path.
Below is an example of a tornado warning and watch statement:
