Son of Weather Grok is an application that displays weather conditions and forecasts for cities from around the world. It taps into NOAA's (National Oceanic and Atmospheric Administration) data center using 4 letter ICAO codes for Airports. A Web page to help you locate these ICAO codes can be found here.

The ICAO is the code with the 4 letters. The codes that use numbers will NOT work. Keep in mind that some remote stations, like most in Afghanistan, do not work. Give it a try, but some of these stations never seem to report any data.

Son of Grok will show the more...

I installed it on my G3/OS 9.2.2. When I restarted, it promptly quit saying it was a type 3 error and to restart the computer. I did so, and the same thing happened again.

delete the application's preferences file, rebuild desktop, try again.


I'm having the same problem with Son of Weather Grok 4.2.2 All I get is an error type 3 when I try to start the program. The previous version (4.2.1) worked fine except for the forcast updates. The suggestion by woofer to trash the prefs and rebuild the desktop did no good.

Confusing to use. I'm trying to look up Danbury Connecticut, found the ICAO number for it, but can't find the forecast number. Thus, when it asks for forecast numbers, I put in "Danbury, Connecticut" but it just thinks for a while and then stops, and nothing's changed. Same for putting in the zip code.

Why not just use weather.com?

Excellant weather finder. I even found my home town on this thing, and that's an accomplishment when your hometown is only 800 people.
