One important key to building resilient communities is an effective warning system. Warnings are designed to give people ample time to find shelter from a natural hazard or to evacuate when necessary. They are also helpful for those who do not pay much attention to weather and/or weather forecasts. Predictions are a large part of being able to produce these warnings. Each community or region has a different warning system depending on the hazard. Although it may seem obvious, it is critical that the public listens and responds in an appropriate manner.
When a tornado vortex signature (TVS) is present in a storm, the national weather service will make the decision to issue a tornado warning for a particular county. These warnings are loud sirens informing the people that there is a tornado hazard, and that they should take cover immediately. Local news stations also will generally interrupt regularly scheduled programming to keep the public updated on where the storm is and where it's going.
Severe thunderstorm warnings could be issued because of storms featuring strong winds, hazardous hail, or cloud to ground lightning. It is best to stay away from windows in case they are busted by hail or blown out by wind. If there is heavy rainfall, travel is discouraged. Once a tornado warning is issued, people are encouraged to take shelter underground. If that is not an option, there are other forms of protection: moving to the lowest, most interior part of their house, wearing protective head gear, etc.
As you can see--and as you have most likely experienced in the past--these warnings serve a purpose in communities. They let you know when to take the necessary precautions that could potentially decrease loss and/or injury, thus reducing the severity of a natural disaster. Unfortunately, there isn't always enough time to take cover during a natural hazard. It's important not to take advantage of the warnings that are given.
