Audio tones emanate from SW+ Alerts (commonly called "wake-me-up alerts") when a Tornado or Severe Thunderstorm Warning is issued for a location being monitored by your device. There have been many question about whether wake-me-up alerts can be heard if one's device is silenced or on Do Not Disturb. iOS devices and Android devices work differently. Let's take them one at a time.
iPhones/iPads
Apple has granted "Critical Alerts" status to SW+ Alerts found in the StormWatch+ app. This means that warnings that require immediate action to protect life and property (Tornado Warnings and Severe Thunderstorm Warnings) will override devices that are silenced, muted, or on Do Not Disturb, sending a loud "wake-me-up" audio tone.
You must have granted the app permission to sound Critical Alerts when you installed/updated to this version of the app. To check whether Critical Alerts are enabled, open your device's Settings app, scroll down and tap StormWatch+, then Notifications, then turn ON "Allow Critical Alerts."

Android devices
On modern Android devices, it is possible for you to configure your device's settings to allow SW+ Alerts audio notifications to override Do Not Disturb when it's activated. (This does not apply to silenced devices.)
From within the StormWatch+ app with an active subscription to SW+ Alerts, tap the Settings button on the Active Alerts card.
Tap "Send Test Notification," which should test your device to make sure your settings are correct and send you a test push notification. On the bottom of that test screen, tap "Go To Settings App," which takes you to your phone's settings for the StormWatch+ app.
You should see your device's app notifications options for StormWatch+. Tap "SW+ Alerts: Wake Me Up Alerts" and scroll to the bottom. You will see "Ignore Do Not Disturb." Turn this ON.
Wake-me-up alerts sent by SW+ Alerts will now sound even if Do Not Disturb is activated on your device.
