To Err on the Side of Caution: Ethical Dimensions of the National Weather Service Warning Process
… traces three ethical dimensions, or values, of weather warnings in the National Weather Service (NWS): an ethic of accuracy, and ethic of care, and an ethic of resilience. Each appear in forecaster work but are not equally visible in the identity of a forecaster as scientific expert. Thus, I …

Effects of Air Temperature and Lake Ice on Snowfall on the South Shore of Lake Superior
Lake Superior is a forcing factor for local weather systems, causing substantial amounts of lake effect snow in the winter (particularly on the south shore). This study assesses decreasing ice cover of Lake Superior and its effects upon synoptic weather factors. Data were collected from eleven …

Determining Knowledge Gaps in Natural Disaster Preparedness: An Exploratory Analysis of Socioeconomic Variables and Response Quality
… that while most respondents reported access to weather alerts and favorable behavioral responses that align with current guidelines from the National Weather Service, gaps are present in comprehension, response timing, and engagement in risky behavior that could delay protective action. Findings …

Spatial scale data requirements using NEXRAD (WSR-88D) for accurate hydrologic prediction in urban watersheds
… deployment of the WSR-88D (NEXRAD) radar by the National Weather Service in 1992 has created the possibility for enhancing flood warning systems. Due to the improved spatial resolution of the radar, a better hydrologic prediction is possible on a real-time basis. Rainfall rates can currently be …

Integrating social media and rainfall data to understand the impacts of severe weather in Argentina
… $222 billion USD in damages. Furthermore, the national weather service in Argentina has a history of operational issues, the most glaring of which is that a single office in Buenos Aires is responsible for forecasting for the entire country. Consequently, there is a large disconnect between the …

Using ensemble precipitation forecasts to improve hydrologic risk assessment at river crossings
Current National Weather Service operations forecast hydrologic conditions probabilistically at most of the United States Geological Survey (USGS) stream gauges across the continental United States. The successful implementation of such an approach, operationally, suggests the hypothesis that a …
