  1. Bonjour and best wishes to all your team,


    I am wondering if if we have information from the Monthly F. system about the weekly probability/anomaly of probability of both snow precipitation and snow cover ? I can't see any on ec.charts.

    Merci

    Thiery



  2. Hi Thiery,

    Sorry those variables are not in echart.

  3. OK...thank you,  pity, since humid anomaly + cold anomaly expected for many parts of Europe...

    by the way, today, the 500hpa weekly anomaly is missing ( empty chart)...

  4. It has been fixed now
