Please provide us feedback on watch / warning maps

The National Weather Service issues a variety of severe weather warnings, watches, advisories, and statements. These warnings, watches, etc. may be issued for a single forecast zone (usually one county or a part of a county) or for many forecast zones. The events are indicated on the map by different colors. Only one event per forecast zone can be shown on the map at a time, a forecast zone may have several warnings and watches in effect but only the most significant threat to life or property is displayed on the map. By clicking on the map to the forecast pages, you can read the text of all warnings, watches, etc. in effect for the forecast zone.
