This book offers a comprehensive description and analysis of natural hazard warnings, drawing on perspectives from the social sciences, physical sciences, and interdisciplinary fields such as disaster studies to articulate a distinction between traditional warnings and what might be called interdisciplinary warnings. Traditional warnings approach warning technology, design, and application from a principally scientific and technical perspective. Human factors, while considered, often are of secondary concern. Interdisciplinary warnings, on the other hand, maintain a critical emphasis on the technical merits of warning systems, but also ask, “Will psychological and community factors such as culture and structure shape how the system is used, and, if so, can this information be incorporated into system design preemptively to make it more effective?” Given the absence of systematic work on interdisciplinary warnings, a book-length monograph discussing and synthesizing knowledge from the various fields focused on warnings and warning response is of critical importance to both academics and practitioners. Broadly conceived, the book presents readers with an in-depth overview of warnings, interdisciplinary research, and interdisciplinary collaboration. The book holds appeal for a very broad audience: scholars; practitioners; and academic, vocational, and technical instructors both in University and non-University settings. It is of interest to academic scholars due to the interdisciplinary treatment of warnings as well as the general presentation of up-to-date scholarship on warning theory. Additionally, scholars interested in interdisciplinary work in general and those focusing on disaster warnings find within the volume a framework for developing collaborative research partnerships with those from other disciplines. As well, the book offers practitioners --emergency managers, mitigation specialists, planners, etc. --a more comprehensive perspective on emergency response in practice, allowing for better development and application of warning policy. Finally, the book appeals to instructors both inside and outside the academy. The authors envision the book useful to professors teaching both graduate and undergraduate-level courses in Sociology of Disaster, Emergency Management Planning, Homeland Security, Disaster Response, Disaster Mitigation, and Business Continuity and Crisis Management. A robust market also exists among professional organizations, perhaps most notably FEMA, which offers countless online and in-person training courses via the National Training Program, Emergency Management Institute (EMI), and other venues.

Severe weather affects many regions of the United States, and has potential to greatly impact many facets of society. This study provides a climatological spatial analysis by county of severe weather warnings issued by the National Weather Service (NWS) between January 1st, 1986 to December 31st, 2017 for the contiguous United States. The severe weather warnings were issued for county-based flash flood, severe thunderstorm, and tornado phenomena issued through the study period and region. Post 2002 severe weather warnings issued by storm warning area were included in this study in the form of county-based warnings simultaneously issued for each affected county. Past studies have researched severe weather warnings issued by the NWS, however these studies are limited in geographic representation, study period, and focused on population bias. A spatial analysis of severe weather warning occurrences by county identify that (a) highest occurrences of flash flood warnings are located in the desert Southwest and Texas, (b) severe thunderstorm warning occurrence is more frequent in Arizona, portions of the Midwest, the South, and the Mid and South Atlantic states, (c) the tornado activity regions of Tornado Alley and Dixie Alley (i.e. Colorado, Kansas, Oklahoma, Arkansas, Texas, Louisiana, Mississippi, Alabama, Tennessee, and Illinois) contained the highest occurrences of tornado warnings, and (d) the highest instances of aggregate warning occurrences are found in the desert Southwest, the Midwest, and the Southern regions of the United States. Generally, severe weather warning "hot spots" tend to be located in those same regions, with greater coverage. This study concludes with a comparison of local maxima and general hot spot regions to expected regions for each phenomenon. Implications of this study are far reaching, including emergency management, and has potential to reduce risk of life.
