Did you know warning sirens are only intended to reach those outdoors? Modern advances in building and window construction continually improves the level of sound entering our home, but doesn't allow outdoor warning sirens to adequately alert those indoors. For this reason, we recommend you consider having a weather radio at home tuned to receive alerts specific to your area.
