NOAA/NWS Short Duration Severe Weather Warnings WMS/WFS

A prototype Web Map Service (WMS) displaying NOAA National Weather Service short duration weather warning polygons. The data are updated on five minute intervals. Note: this service displays only the 'polygonal' warnings for severe weather events (flash flood warnings, severe thunderstorm warnings, special marine warnings, and tornado warnings), it does not include other watches or hazards that may be active in a particular area.

For full information about active warnings, watches, hazards, and alerts, please see the National Weather Service page at: http://www.nws.noaa.gov/view/largemap.php.

Source data for this service can be found here: http://www.nws.noaa.gov/gis/shapepage.htm.

This is a prototype service available on NOAA's Open Geospatial Consortium shared hosting service. The hosting system is monitored for uptime and is geographically distributed in a high-availability architecture with two mirrored nodes. However, it should not be relied upon for 24 x 7 uptime for emergency response.
