The Iowa DOT has removed the external communications for the Orange City (KORC) AWOS today (28 Feb 2019). This ends the data collection from the site. The station is being replaced by a station located at the Sioux County Regional Airport (KSXK). It is expected for this new station to appear online next week (first week of March).
The Iowa DOT has taken over the maintenance of an AWOS station at the Hampton, IA Municipal Airport. So that means the data is now disseminated to the world and thus this very website! The site identifier is KHPT. You can find more IEM information for this site here.
18 sites in the Iowa AWOS network went offline Friday morning (1 July 2016). The Iowa DOT, who manages the network, note that a communications contract changed at the time and it will take until after the holiday weekend for the sites to be restored.
