SharpAlert can possibly save your life when an event occurs.

Simplifying a bit, SharpAlert works closely to how Wireless Emergency Alerts would work on a device like your phone, or more closely to the Emergency Alert System on a TV or radio station broadcast. In the background, SharpAlert constantly polls for new alerts. When an alert is received, the program checks it against your preferences. If the alert is allowed to relay, a visual and auditory message plays. It tells you the event type, and information about the alert. You can play TTS (Text-To-Speech) or embedded audio (included within some alerts) by clicking the play button. TTS or embedded audio will be played automatically if you have SharpAlert in full screen mode.

SharpAlert can receive alert information from the United States in the form of both IPAWS (Integrated Public Alert & Warning System) and the NWS API (National Weather Service API), Canada in the form of NPAS (National Public Alerting System) [Listed in SharpAlert as NAADS], Mexico in the form of SASMEX (Sistema de Alerta Sísmica Mexicano), and Brazil in the form of IDAP (Divulgação de Alertas Públicos). Each option is pick and choose, as they can be enabled and disabled separately at any time within Region Settings. You'll need to restart the program if you change them!

Alert sounds can be customized within SharpAlert.
If you want to send a test alert at any point, press CTRL + WIN + SHIFT + T.

Severe Emergency Alert (Played when the alert severity is Severe or higher)

Moderate Emergency Alert (Played when the alert severity is Moderate or lower)
