Discussion: Due to a dry spring and summer climate across Central Europe the Rhine River levels continue to descend. A minimum river level was observed last week at Ruhrort, Cologne and Kaub (Germany) along the Rhine River. However, new minimum levels are observed today in each of these locations (Fig. 1-3). The river level drop is 45-65% of levels observed just 30 days ago. The 90-day observed precipitation amount (Fig. 4-5) is sparse from northern Germany (Bremen) to southern Germany (Stuttgart).

The 15-day ECM ensemble forecasts more dry weather over the next 15 days across Central Europe (Fig. 6). Temperatures are generally marginally warmer than normal. Rhine River levels will continue to lower the second half of July.
