Storm Shield app's storm-based polygon warnings are extremely accurate. Storm-based alerts help reduce false alarms by alerting you to severe weather based on your exact location within a county. You will only receive weather alerts if your current location or a saved location falls inside a watch/warning box. Many other products still use county-based alerts (meaning you'd get an alert even if your location in the county is not within the threatened area). If you are alerted from another service but do not get an alert from Storm Shield, please check the alert type overlay on the app’s radar map in order to see if your location actually falls inside the polygon alert.

After installing Storm Shield, you must open and configure the app to receive weather alerts for your Current and Saved Locations by giving Storm Shield permission to follow your current location and giving permission to send you push notifications. Once you have configured the app, you don’t need to keep it open to receive alerts.

To receive alerts for your Current and Saved Locations, see the Current Location, Saved Locations, and Receiving Severe Weather Alerts sections under Configuring Storm Shield 3.0.

Check your Weather Alert settings. Tap the Gear icon in the upper-left corner of the screen, then Manage Weather Alerts. You can enable or disable alerts by tapping an alert type. Checkmarks indicate alerts that are enabled for your device.

If you are using an iOS device that doesn’t include a GPS or a cellular connection, its ability to determine your current location is limited. This includes all current iPod touch models and some iPad models. Those devices rely on Wi-Fi signals to determine your location.
