This map presents information about current United States weather watches and warnings that have been issued by NOAA’s National Weather Service (NWS). This map was developed as part of the United States Geological Survey’s (USGS) Natural Hazards Support System (NHSS) which is available at http://nhss.cr.usgs.gov. But although this application was developed by the USGS, it contains data and information from a variety of public data sources, including non-USGS data. Therefore detailed information about each of these data providers, including specific data source, data currency and disclaimers, is provided at http://nhss.cr.usgs.gov/data.shtml.
