Wireless Emergency Alerts (WEA) are grouped into five alert classes:

1. Presidential (reserved for the Office of the President)
2. AMBER (reserved for National Center for Missing and Exploited Children)
3. Imminent Threat
4. Public Safety
5. WEA Test

Alerting Administrators will determine which event codes fit the criteria for Imminent Threat and/or Public Safety. In order to successfully send a WEA, an alert must adhere to the following requirements:

• Urgency: Immediate or Expected
• Severity: Extreme or Severe
• Certainty: Observed or Likely
