NEXRAD radar map for weather (PC)

The TeleType GPS software supports up-to-date NEXRAD radar maps. The software contains information for 154 NEXRAD radar stations, which in total provide complete coverage of the United States. This will allow a pilot to safely detour around inclement weather when flying. Note that to be able to download up-to-date maps, the PDA or PC must be connected to the Internet.

To see the current weather maps in your web browser you can go to http://www.crh.noaa.gov/radar/ and select the radar station closest to your current location. For more information on what the colors represent on the radar maps, you can go to http://weather.noaa.gov/radar/radinfo/radinfo.html#color.

NEXRAD radar stations are represented by blue diamonds on the map. To display the radar locations, the US_Radars.ttm map file must be loaded into the software.

You must have a license to access this feature.
