Weather alerts are essential tools that inform the public about hazardous weather conditions, enabling timely and appropriate responses to protect life and property. In the United States, the National Weather Service (NWS) issues various alerts, each with specific meanings and recommended actions.

How Do Wireless Emergency Alerts (WEA) Work?

Wireless Emergency Alerts (WEA) are emergency messages sent by authorized government authorities through your mobile carrier. These alerts can include weather warnings, local emergencies, AMBER Alerts, and Presidential Alerts during national emergencies. WEA messages are typically short, up to 90 characters, and include a unique tone and vibration to distinguish them from regular messages. No signup is required; WEA messages are sent automatically to WEA-capable phones during an emergency. (weather.gov)
