Why SW+ Alerts?

Well over a decade ago, the National Weather Service began issuing Tornado, Severe Thunderstorm, and Flash Flood Warnings as polygons, alerting only the areas in the path of the storm, rather than entire counties. However, most outdoor warning sirens, NOAA Weather Radios, and many other public alert systems still sound for entire counties! This creates an overwarned and desensitized public, increases the perceived warning false alarm rate, and reduces the effectiveness of the warnings. Smartphone technology, when combined with the coordinates of the NWS warnings, is the BEST and FASTEST option for accurately and promptly warning the public. Enter SW+ Alerts.

Did you know?
At a "Weather-Ready Nation" conference in Oklahoma City, panelists stated that cell phones and geo-targeted alert information are the most important warning dissemination technology available. In addition, a finding of the NWS Service Assessment of the Joplin, MO EF-5 tornado indicated that "many current warning dissemination systems are not fully compatible with specific warning information provided by storm-based, warning polygons." Officials at the highest level are giving credence to the use of geo-targeted alerts and warning systems that can provide very specific information.

The experts believe in the technology - so should you!
