Authoritative Source

Watch, Warning, and Advisory alerts direct from the National Weather Service since 2010. iAlert has carried official NWS severe weather products for nearly two decades.

How It Works

From alert issuance to you in seconds.

  1. 01

    Issued

    The National Weather Service issues a Watch, Warning, or Advisory. iAlert receives the official message the moment it's released.

  2. 02

    Routed to your locations

    The alert is checked against every location you've saved. Alerts outside your areas are filtered out. Alerts inside are delivered.

  3. 03

    Delivered

    When an alert hits one of your locations, it goes out through every channel you've turned on. Email, text, or a phone call that reads the alert aloud.

Questions, answered

Before you subscribe.

What's the difference between a Watch, a Warning, and an Advisory?
A Watch means conditions are favorable for severe weather. A Warning means severe weather is occurring or imminent and you should take action. An Advisory flags conditions that may cause inconvenience or hazard but are below the Warning threshold. iAlert carries all three.
How fast do alerts arrive after the NWS issues them?
Alerts are dispatched the moment the NWS releases the product. Delivery time after that depends on your channel: email and text typically arrive within seconds; phone calls take a few seconds longer to place.
Can I pick which alert types I receive?
Yes. Your account configuration controls which severe weather alerts are routed to your locations. The Configuration Guide PDF below walks through the per-location and per-alert settings.
Does the phone call really read the alert aloud?
Yes. When a covered alert hits one of your locations, iAlert places an automated voice call that reads the alert type, the area covered, the in-effect window, and more. The sample above is representative of the format.
What devices can receive the text channel?
Any SMS-capable mobile number works. iAlert sends standard text messages, so the alert lands wherever your phone receives texts. One text-enabled device is included per subscription.
Can I add Severe Weather to an existing iAlert account?
Yes. Add the service to your cart and log in when prompted during checkout. Once signup is complete, you can immediately configure Severe Weather Alerts for your locations. Many users subscribe to multiple iAlert services to meet their needs.
Is there a cap on how many alerts you'll send me?
There is no cap. Weather alerts are event driven, so if an alert matches your selected alert type and location, it will be sent. You can manage how and when you receive alerts using controls such as quiet hours, paused alerts, alert selection, and location settings.
How do I cancel?
Cancel anytime from your iAlert account. The subscription ends at the close of the current billing month and no further charges occur.
