Problems with Outdoor Sirens

The use of outdoor warnings sirens has come under debate over the last few years. The main problem is that they are very expensive to install and also very expensive to maintain. The sirens are a carryover from the cold war and were first used by civil defense to earn of an impending nuclear strike. After the cold war they began to use them for severe weather. Due to changes in how buildings are constructed and the use of better insulating materials and the addition of air conditioning, it has become very difficult to hear the warning sirens.

In addition in high wind events, the sound of the siren is greatly reduced if you are upwind. As such it is strongly encouraged that families and businesses invest in a weather radio. The national weather service sends out an alert for their respective areas and you can set the area you live in to receive the alerts. The use of cells phones is also an option and they will also receive the weather alerts. Lastly, use local media to listen on minute to minute updates on severe weather.

All Clear

There is no "All Clear" given by the National Weather Service. Once the Watch or Warning has expired, it is up to each individual to assess and see that it is safe to come out of your shelter.
