Information about the Emergency Managers Weather Information Network

EMWIN is an acronym for the Emergency Managers Weather Information Network.  This service is provided free by the National Weather Service.  EMWIN is a live data stream broadcasted by the National Weather Service for use by emergency managers and others.  This data stream contains weather warnings, watches, images, advisories, and  forecasts issued by the National Weather Service.

The information present in the EMWIN data stream originates from local weather service offices and other sources.  This information is collected at the National Weather Service office in Silver Spring, Maryland.  From there, it is up-linked to the GOES East and GOES West weather satellites from a transmission site in Wallops Island, Virginia.

You can obtain it directly from the GOES weather satellites with a satellite receiver.  One option is the NooElec Satellite bundle.   A write up on this system is available at here.

In December 2019, the National Weather Service discontinued the EMWIN Internet data service.  This service was reestabilished in January 2022 by Weather Message Software LLC.  Users can now receive EMWIN data using the original EMWIN software.  The base server address is emwin.weathermessage.com port 2211. You can see the live status of the network and available servers.
