Description: <div>This feature service depicts the <a href='https://www.weather.gov/' rel='nofollow ugc' target='_blank'>National Weather Service</a> (NWS) watches, warnings, and advisories within the United States. Watches and warnings are classified into <a href='https://www.weather.gov/lwx/warningsdefined' rel='nofollow ugc' target='_blank'>43 categories</a>.</div><div><ul><li>A warning is issued when a hazardous weather or hydrologic event is occurring, imminent or likely. A warning means weather conditions pose a threat to life or property. People in the path of the storm need to take protective action.</li><li>A watch is used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location or timing is still uncertain. It is intended to provide enough lead time so those who need to set their plans in motion can do so. A watch means that hazardous weather is possible. People should have a plan of action in case a storm threatens, and they should listen for later information and possible warnings especially when planning travel or outdoor activities.</li><li>An advisory is issued when a hazardous weather or hydrologic event is occurring, imminent or likely. Advisories are for less serious conditions than warnings, that cause significant inconvenience and if caution is not exercised, could lead to situations that may threaten life or property.</li></ul><span style='font-weight:bold;'>Source</span></div><div><ul><li>National Weather Service RSS-CAP Warnings and Advisories: <a href='https://alerts.weather.gov/' rel='nofollow ugc' target='_blank'>Public Alerts</a></li><li>National Weather Service Boundary Overlays: <a href='https://www.weather.gov/gis/AWIPSShapefiles' rel='nofollow ugc' target='_blank'>AWIPS Shapefile Database</a></li></ul></div><div><span style='font-weight:bold;'>Update Frequency</span></div><div><ul><li>The services is updated every 5 minutes using the <a href='https://www.esriurl.com/LiveFeed' rel='nofollow ugc' target='_blank'>Aggregated Live Feeds methodology</a>.</li><li>The overlay data is checked and updated daily from the official <a href='https://www.weather.gov/gis/AWIPSShapefiles' rel='nofollow ugc' target='_blank'>AWIPS Shapefile Database</a>.</li></ul></div><div><span style='font-weight:bold;'>Area Covered</span></div><div><ul><li>United States and Territories</li></ul></div><div><font size='3' style=''>What can you do with this layer?</font></div><div><ul><li>Customize the display of each attribute by using the <a href='https://doc.arcgis.com/en/arcgis-online/create-maps/change-style.htm' rel='nofollow ugc' target='_blank'>Change Style</a> option for any layer.</li><li>Query the layer to display only specific types of weather watches and warnings.</li><li>Add to a map with other weather data layers to provide insight on hazardous weather events.</li><li>Use ArcGIS Online analysis tools, such as Enrich Data, to determine the potential impact of weather events on populations.</li></ul><span style='color:rgb(128, 128, 128);'><span style='background-color:rgb(255, 255, 255);'>This map is provided for informational purposes and is not monitored 24/7 for accuracy and currency.</span></span></div>
