EMWIN
The Emergency Managers Weather Information Network (EMWIN) is a service sponsored by the U.S. National Weather Service to broadcast real-time weather data and warnings. EMWIN provides continuous dissemination of critical meteorological information to emergency managers, government agencies, and interested private users to enhance public safety, support disaster response, and aid weather forecasting..
EMWIN (Emergency Managers Weather Information Network) is a data broadcast system managed by the U.S. National Weather Service. It disseminates national and local weather data, forecasts, warnings, and graphics in near real-time over a variety of communication protocols, facilitating rapid distribution to emergency managers and interested parties.
Port 2211 serves as an endpoint for EMWIN data transmission over IP networks using both TCP and UDP. Organizations utilize this port to receive weather data feeds directly for integration into their alerting systems and decision support tools. The protocol ensures broad accessibility, and resilience via satellite broadcasts and internet relay points, thus bolstering communication redundancy during emergencies.
EMWIN-compatible applications process the data stream provided via this port, converting NWS products into formats suitable for internal alerting, situational awareness dashboards, or redistribution. Its multi-protocol design supports varying bandwidth and infrastructure environments, making it a flexible choice for critical weather information delivery.
