WeatherCall® continuously monitors the National Weather Service's NOAA weather wire. Our system compares a client's specific location to the location of the warning area.

When a severe weather warning includes your location, you will receive a phone call from WeatherCall®. It doesn't matter what time of day, or if it is a weekend, you will receive a call.

You can also receive the warning by email with a detailed map of the threat or by text message.
