For continental USA, Alaska, Hawaii and southern Canada, users of
FUGAWI GPS software can now subscribe to a Doppler weather radar
service, which will overlay live weather data directly on top of
nautical charts during navigation. All that is required is a copy of
FUGAWI software, an internet connection and a subscription to
WeatherPort.
