Emergency Broadcast System Alert Notifications

Emergency Broadcast System Alert Notifications

Have you ever wondered what alerts the Emergency Broadcast system shares? They offer alerts to weather-related events, such as flood and hurricane warnings, and non-weather related alerts, such as amber alerts and evacuation notifications. The broadcast system uses NOAA weather radios to send the alerts to anyone with a weather radio. A NOAA weather radio offers alerts for all events across the Emergency Broadcast System, so your Halo+ will notify you about both weather and non-weather related events if you choose.

The National Weather Service also offers information about the types of messages sent across the emergency broadcast system.

A WARNING is an event that alone poses a significant threat to public safety and/or property, probability of occurrence and location is high, and the onset time is relatively short.

A WATCH meets the classification of a warning, but either the onset time, probability of occurrence, or location is uncertain.

An EMERGENCY is an event that, by itself, would not kill or injure or do property damage, but indirectly may cause other things to happen that result in a hazard. For example, a major power or telephone loss in a large city alone is not a direct hazard, but disruption to other critical services could create a variety of conditions that could directly threaten public safety.

A STATEMENT is a message containing follow-up information to a warning, watch, or emergency.
