Basic Introduction to EMWIN

The Emergency Managers Weather Information Network -- EMWIN -- is a service that allows users to obtain weather forecasts, warnings, and other information directly from the National Weather Service (NWS) in almost real time. EMWIN is intended to be used primarily by emergency managers and public safety officials who need timely weather information to make critical decisions.

However, anyone with a personal computer running Windows can be an EMWIN user.

EMWIN basically consists of two things:

1. A round-the-clock data feed of current weather warnings, watches, images from NESDIS, advisories, forecasts, and other products issued by the National Weather Service.

2. A suite of methods to obtain this data feed and display the products on your personal computer.

 

The primary method for obtaining the EMWIN data stream is direct from the GOES East or West satellites.  To receive the satellite broadcast you will need special hardware, such as a satellite dish and LNA etc. You can learn more about the hardware by contacting one or more of the EMWIN vendors listed on the Commercial Vendors page.

 

Another method is to use the EMWIN ByteBlaster network. If you don't want to buy the broadcast hardware, the program by itself provides a couple of methods for obtaining the EMWIN feed directly over the Internet .  One of these methods is called Internet push, because it automatically 'pushes' a continuous stream of data across your internet connection into your PC.
