Identifying and Mapping Vulnerable Weather Hotspots in Middle Tennessee

The weather impartially affects individuals regardless of their background, but its consequences can be disproportionately severe for those who are less fortunate or vulnerable. Therefore, it is crucial to identify these areas and ensure that the individuals residing there are informed about the impending impacts by both the National Weather Service (NWS) and corresponding Emergency Managers. The areas that have been identified as more vulnerable to weather impacts encompass a range of locations, including churches, schools, large outdoor recreation areas, nursing homes, mobile home parks/campgrounds, non-English speaking areas, hospitals, areas near low-water crossings, and areas prone to floods and flash-floods.

Data collection from counties within the jurisdiction of NWS Nashville involved the implementation of two methods. A few counties actively participated in in-person meetings by facilitating direct engagement and information exchange, while others completed a comprehensive survey enabling efficient data gathering. This approach ensured that data was obtained from as many counties as possible and enhanced the overall accuracy and inclusivity of information. Following data collection, the information was plotted into ArcGIS Pro and exported as a shapefile to be used in the Advanced Weather Interactive Processing System (AWIPS) software, providing vital information to NWS forecasters and enhancing Decision Support Services (DSS). This significant project has the potential to save lives as well as enhance local knowledge of vulnerable population locations. Looking ahead, implementing an online map with this data will not only enable Emergency Management to provide more frequent updates to vulnerable population locations but also allow access to other reliable groups that may be able to contribute further enhancements. Additionally, this data can be programmed into WarnGen and displayed in warning products to both call out these locations that may not realize are vulnerable and provide specific locations that may assist the public in understanding the geographic impact of the warning. By harnessing technology and amplifying accessibility, we can ensure that crucial information reaches those in need more effectively, strengthening preparedness and resilience in the face of weather-related challenges.
