The hydrological precipitation deficit – the combination of low precipitation and high evaporation – has exceeded that of both 1976 and 2018 for the first time. That says hydrologist Patrick Willems on Twitter on Sunday.

According to the KU Leuven professor, the hydrological deficit is more than 350 millimeters, or 350 liters of water per square kilometer. This is an average for the whole of Flanders, with some regions – such as parts of East and West Flanders – being hit harder than others.

The precipitation deficit is calculated from the start of the hydrological summer, on April 1. From then on, proportionally more water evaporates than precipitation falls. So now, after more than 150 days, we have a historically high deficit, according to data from Patrick Willems.

Such a hydrological deficiency occurs on average about once every fifty years, according to the table on Twitter. Not only the lack of rain was striking this year, but also the large evaporation due to the many sunshine and high temperatures, Willems said earlier.

Code orange for twelve Luxembourg municipalities

In the province of Luxembourg, twelve municipalities are being asked to limit their water consumption. The drinking water in these municipalities comes from the Nisramont reservoir, but the water there is historically low, according to the Walloon water company SWDE (Société wallonne des Eaux), which has issued a warning.

These are the municipalities of Bastogne, Bertogne, Fauvillers, Houffalize, La Roche, Marche-en-Famenne, Martelange, Neufchâteau, Rendeux, Sainte-Ode, Vaux-sur-Sûre et Wellin. ‘The code orange is a recommendation, not an obligation. It is a precautionary measure,” said the SWDE spokesperson.
