About

Severe weather alerts are designed to give you line of sight, on weather that could impact your safety.

For members only in the continental US only.

Definition of a severe weather alert

The National Weather Service has three categories of alerts:

– Watch

– Advisory

– Warning

A warning indicates that conditions pose an imminent threat to life or property, and that travel will become difficult to impossible.

The scope for Core Lite is Warnings only. In Core Lite, this terminology has been re-titled to Severe Weather Alerts, to convey to the user, the severity of the event.

For more on severe weather criteria see US weather advisory

Scope

National weather warning alerts are issued based on two geo areas, County and Zone.

Some of the many severe weather alerts include:

– Severe Thunderstorm

– Tornado

– Flash Flooding

– Excessive heat

Frequency of alert checks

Core Lite checks for active alerts every 15 minutes, at 00, 15, 30, 45.

Triggers for alert in Core Lite

The alert is triggered when you enter a County, that is subject to an active severe weather alert.

An alert is displayed:

– When creating a safety plan for a location and an active alert is in place

– When you have an active safety plan, you are inside the safety zone and an active alert is in place

– You are using a live sharing feature and enter a county where an active alert is in place

The alert data is supplied by the National Weather Service (US). See Terms of Service for more.
