What is EMWIN?

What Can EMWIN Do?
Using a point-and-click interface on a Windows-based PC, EMWIN users can monitor the latest severe weather watches, warnings and statements for their county (or any county in the U.S.).

How Does EMWIN Work?
The National Weather Service transmits the weather data via weather satellites (GOES 8 and GOES 10). The data signal is available free of charge. Initial start-up costs are around $1000 if you have a computer available (or $2500 for a complete, "turn-key" system). The one-time cost includes a satellite dish, interface box, and software. There are no recurring costs.
