iAlert Help & FAQ

iAlert delivers affordable, dependable weather alert notifications covering severe weather, lightning, forecast triggers, and real-time observations, for individuals and organizations of any size.

About iAlert

What is iAlert?

iAlert is a weather alert notification service that keeps individuals and organizations informed when weather puts people, property, or operations at risk. Subscribers receive alerts by email, SMS text, or automated phone call, delivered automatically based on the locations and alert types they configure.

How does iAlert work?

iAlert aggregates official NWS watches, warnings, and advisories alongside real-time lightning detection feeds, METAR surface observations, and forecast model output. Custom meteorological analysis is applied across all streams to determine alert conditions. When conditions match a subscriber's configured locations and thresholds, iAlert pushes a notification immediately with no app to open and no page to check.

How is iAlert different from free weather apps?

Free weather apps require you to open them and check conditions yourself. iAlert pushes alerts to you the moment they are issued, by the channel you choose: email, text, or phone call.

iAlert also uses official NWS polygon-based alerting, meaning you receive a warning only when your exact location falls inside the official NWS warning boundary. County-based systems alert everyone in a county even if the event only affects one corner of it. Polygon-based alerting is more precise in both directions: you get the alert when it matters, and you are not woken up for weather five towns away.

Is iAlert a government service?

No. iAlert is operated by iAlert Services, LLC, a privately owned American media company founded and led by a former National Weather Service meteorologist. iAlert processes and distributes official NWS data but is not affiliated with or operated by the federal government.

What geographic areas does iAlert cover?

iAlert covers the continental United States, Alaska, Hawaii, and U.S. territories for NWS-based weather alerts. Coverage scope varies by alert type; see the individual service pages for details.

Alert Types

What kinds of weather alerts does iAlert send?

iAlert supports a full range of weather alert types:

  • Severe weather warnings and advisories: tornado, flood, severe thunderstorm, hurricane, winter weather, and more
  • Lightning detection alerts based on real-time strike data
  • Hourly and daily forecast threshold alerts
  • METAR surface observation alerts
  • NWS local storm reports
What is the difference between a watch, warning, and advisory?

A watch means conditions are favorable for a hazardous weather event: stay aware and prepare to act. A warning means the event is imminent or already occurring: take protective action now. An advisory means conditions may cause inconvenience or minor hazards but are generally less serious than a warning. iAlert delivers all three levels.

Does iAlert send lightning alerts?

Yes. iAlert's lightning detection service monitors real-time lightning strike data and sends alerts when strikes occur within a configurable radius of your location. This gives construction crews, outdoor event operators, recreation facilities, and schools enough lead time to act before conditions become dangerous.

Does iAlert send daily and hourly forecast alerts?

Yes. iAlert's forecast alert services let you set thresholds (temperature, wind speed, precipitation probability, and more) and receive a notification when a forecast crosses those values. Daily forecast alerts and hourly forecast alerts are available as separate subscriptions.

What are local storm reports?

Local storm reports (LSRs) are ground-truth observations submitted by NWS spotters, emergency managers, and trained observers when significant weather occurs: hail size and location, wind damage, flooding, tornado touchdowns. iAlert's storm report alert service delivers LSRs for your configured area as they are issued by NWS.

Does iAlert cover observation-based alerts?

Yes. iAlert's observation alert service monitors METAR surface observations from nearby weather stations and sends alerts when conditions cross thresholds you set: wind speed, visibility, temperature, or other parameters. This is useful for operations that depend on current observed conditions rather than forecasts.

Alert Delivery

How are iAlert alerts delivered?

Alerts are delivered by email, SMS text message, or automated phone call. Subscribers choose which delivery channels they want for each alert type. Some subscription plans support multiple simultaneous delivery channels for the same alert.

How quickly are alerts delivered after NWS issues an event?

iAlert processes NWS data continuously. Most alerts are delivered within seconds to a few minutes of NWS issuance, depending on alert type and delivery channel. SMS text and automated phone calls are typically fastest.

Can I get alerts for more than one location?

Yes. iAlert accounts support multiple alert locations. Each location can be independently configured with its own alert types, delivery channels, and thresholds. This is useful for monitoring a home, a worksite, and a family member's address simultaneously.

Why did I receive an alert for weather that was not directly over me?

iAlert uses the official NWS warning polygon, the geographic boundary drawn by NWS forecasters for each warning event. If your location falls inside that polygon, you receive the alert. This is more precise than county-based alerting, but warning polygons may extend beyond the most intense weather area.

Conversely, if your location is outside the polygon, you will not receive the alert even if a neighboring area does. This is by design: the NWS polygon represents where forecasters determined the threat exists.

Do I need a smartphone or app to receive iAlert alerts?

No. iAlert delivers alerts by email, SMS text, and phone call, all of which work on basic phones. No app download is required. You manage your account settings from any web browser.
