Disable weather report service

On my RHEL6 server, a process that I haven't been able to identify is periodically opening a connection to a www.noaa.gov server, presumably to request a weather report. This is probably to support the weather report applet for Gnome desktop. I would like to turn off this service, but I haven't been able to identify it. Does anyone know where this service is configured and how to disable it? No weather report icon is showing on either of the default desktops. Thanks!
