Storm Shield is a life-saving app that is like a NOAA Emergency Weather Radio for your iPhone and Android device. Get storm-based alerts for life-threatening weather events like tornado, hurricane, flood, thunderstorms and more via voice and push notification. You control which alerts you want to receive.
As an example, the National Weather Service issues a polygon for a Severe Thunderstorm Warning. This only affects people in the path of the dangerous part of the storm. If your location is inside the orange polygon, you would receive a Severe Thunderstorm Warning from Storm Shield.
If your location is just outside the polygon (even though you may be in the storm and the county), you would not receive a warning from Storm Shield.
