The Chesapeake Bay Climate Impacts Summary and Outlook is a recurring seasonal series produced by the National Oceanic and Atmospheric Administration's (NOAA) Mid-Atlantic Regional Integrated Sciences and Assessments (MARISA) program. The focus of the series is on historic and future seasonal weather and climate variability and trends in the Chesapeake Bay Watershed. This web-based tool draws on information from other regional climate centers, news and weather sources, regional climate data sets, and the best available science on projected future climate impacts. The aim of the tool is to present useful information for Chesapeake Bay Watershed policymakers, practitioners, residents, and community leaders. The tool presents an in-depth analysis on multi-decadal historic and future changes in seasonal precipitation and extreme precipitation events that are displayed on interactive maps.
