Inden den lange periode med tørt vejr i sommeren 2007 var vandreserverne i jorden allerede faldet betydeligt i store dele af Rumænien som følge af fremskyndet vandfordampning foranlediget af temperaturer over gennemsnittet i vinteren 2006/07 og foråret 2007.
Before the long-lasting spell of dry weather in the summer of 2007, water reserves in the soil had already strongly decreased in large parts of Romania, due to accelerated water evaporation caused by higher than average temperatures during winter 2006-2007 and spring 2007.
