Severe Weather Alerts
Severe Weather Alerts are an automated service that displays weather alerts on your website in the Rayos Alert Banner and in the Weather Alert Banner widget. Once configured, Rayos will display a warning on your website when the National Weather Service has indicated there is a severe weather event in your selected areas.
Severe weather alerts can automatically trigger two different elements on your site:
- The Weather Alert Banner is a page element that typically placed in the right rail of landing pages and automatically appears when alerts are triggered.
- The Rayos Alerts bar is the same alert bar that is used for your breaking news alerts. Rayos can automatically trigger this alert bar for severe weather.
These two alert elements have there own settings in the admin, allowing you to trigger one or both based on different weather events and severity levels.
Instructions for initially configuring alerts and building the Severe Weather Alerts page are below. If you have an existing Severe Weather Alerts page and want to edit your alert configurations, follow the Configuring Alerts steps.
Configuration & Setup
To set up Severe Weather Alerts, the following is needed:
- You need to decide on the Zip Codes of areas covered, alert types and the minimum alert severity level
- Configuration of alerts for the Weather Alert Banner and the Rayos Alerts bar.
- Place Severe Weather Alerts banners
- Build and set the Severe Weather Alerts page

Weather Alert Banner Example
Configure Severe Weather Settings
The configuration options for the Weather Alert Banner are focused on three types of data:
- Zip Code
The area covered by the automated Weather Alerts is determined by defining the Zip Codes you would like to cover. Enter the zip codes individually in the search box then click Add to List. - Events
You will be able to choose the weather events, such as Tornado Watch or Flood Warnings. Just check the box to the events you want to trigger alerts on. To better understand the types of alerts, review the National Weather Service’s Warning Definitions.
Some alert types are also alerts in the government’s Emergency Alert System (EAS). These alert types tend to be very reliable. They are designated below with the (EAS) tag. Other alerts are put out by the National Weather service as text alerts, which means Rayos keys off a text string entered by human beings to understand what type of alert is being sent. These alerts can be missed if the National Weather Service misspells the name of the alert or uses a slightly different term. - Alert Severity
The National Weather Service sets a severity level for alerts based on the severity of the weather event. You can choose the minimum severity level alerts must reach to display on your site. All alert types must be set to the same minimum severity. The options are:- Extreme
- Severe (recommended)
- Moderate
- Minor
Configure Web Banner/Web List Settings
To configure what events and severity automatically trigger the Rayos Alert bar during severe weather:
The Severe Weather Alert Web Banner
When there is an active alert the Alert Banner will be triggered to display on your site. This banner can be placed on as many pages as desired in any location. The most common location is the top of the right rail on the homepage and weather page.
If a visitor clicks on the link to the alert details, they will be brought to a page that shows the types of active alerts and the alerts for all counties or zones impacted.
To Add The Severe Weather Alerts Banner To A Page Or Template

The Rayos Team recommends placing the Alerts Banner at the top of the right rail on your homepage and weather pages at a minimum.

Frequently Asked Questions
Why does the alert text have random characters or strange formatting/text?
The text in the alert is directly from the National Weather Service. During a severe weather event, the National Weather Service is often more concerned with speed than copy editing. There are often typos and extra characters in these alerts.
Why do some counties or zones appear twice on the alert page list?
Sometimes, the National Weather Service sends multiple alerts with just an additional sentence changed within minutes of each other. This can cause duplicates.
The Rayos Team continues to investigate ways to prevent this form happening, while still maintaining the integrity of the data. Stay tuned for updates as we refine our handling of the feeds.
