Development of Hybrid Notification Systems for Use in Storm-Based Warnings in Rural Communities

This case study compares capabilities of existing emergency alert sirens and the wireless emergency alert (WEA) system in Calhoun County, Alabama, using storm-based warning polygons. Using siren ground cover, mobile phone tower ground cover, building data, and census population data, it is possible to compare and contrast the reach of these emergency warning systems within a real-world environment for localized emergency test cases. This paper concludes by suggesting the addition of a hybrid warning system using only existing technology that could minimize both false-negative and false-positive warnings in low-density areas, maximizing both safety and efficiency of warning systems.
