The following information should be helpful if you are wondering whether you should renew your WRAL WeatherCall subscription because you haven't gotten any severe weather warning phone calls.
A key aspect of WRAL WeatherCall's value lies in the major difference between the way severe weather warnings have traditionally been issued in the past, compared to the way WRAL WeatherCall issues warnings to our subscribers.
Traditional (county based warnings) vs. WeatherCall (storm based warnings)
Severe storm warnings have traditionally been issued to everyone in a county (or multiple counties) even though the actual severe weather area typically only threatens a small fraction of the entire county's area. This traditional method results in warning many more people than those who are actually in the threatened area.
The WRAL WeatherCall system constantly monitors the latest official National Weather Service information, and only calls you when a severe weather warning threatens your home's immediate area.
The shape of the warning is everything!
The following images help illustrate the difference between traditional (county-based) and WRAL WeatherCall (storm-based) weather warning systems.
The left side of the image shows a storm's actual radar signature which is moving primarily through 2 counties (outlined in white). The actual National Weather Service tornado warning area appears as a polygon outlined in bright red. The area inside the bright red polygon is the only area which the National Weather Service tornado warning actually applies. The same polygon warning area also appears in red on the right side of the above map image.
Under the traditional warning system, everyone in both counties would have been received the tornado warning. With WRAL WeatherCall's advanced technology, only those who live inside the bright red polygon would have received an alert phone call.
The WRAL WeatherCall Advantage
As a WRAL WeatherCall subscriber, you can have confidence that your home's location will be monitored 24 hours a day, 365 days a year. You will only receive an alert phone call if your home's address is inside the boundaries for a National Weather Service-issued severe weather warning!
