Actual situation 20/04/25 17:55

An automated collection of the latest international ice reports and a graphic representation of the ice situation on the fairways. The colors show the status of the reports: black is a report from today, blue a report from yesterday and green shows that there is no report within the last two days (meaning no ice or no report!).
The fairways denominations after the report (AA, BB, ...) are a link to a representation of the ice conditions of the last 10 days on the respective fairway. Each day is given by a bar, the height gives the ice thickness, the color the ice concentration and symbols below give information about rafted or ridged ice. A ? denotes missing information.
