Inzwischen sind die Brände vollständig gelöscht. Starker Regen hat der Feuerwehr bei Beelitz und bei Treuenbrietzen südwestlich von Berlin beim Löschen geholfen.

The risk of forest fires decreased significantly in Brandenburg on Saturday. However, this could only mean a short break, because the German Weather Service predicted the highest danger level for some regions for Monday. At the start of the week there should also be a lot of heat again.

According to an overview by the State Ministry for the Environment on the Internet, levels 1 and 2 applied to almost all districts in Brandenburg on Saturday, which means a very low to low risk. “Human actions cause more than 90 percent of all forest fires with up to 99 percent of the forest fire damaged areas,” it said. There had been more than 350 fires since the beginning of the forest fire season with great drought in Brandenburg.

The heat of the past few days has probably spoiled bathing fun in some places, as more blue-green algae can appear in water. Swimming and surfing in the Fahrlander See in Potsdam, for example, was banned days ago. The Teltow-Fläming health department also issued a warning for beach baths because of the algae.

Blue-green algae pose a health hazard because the cyanobacteria can cause skin irritation, nausea and vomiting in humans. Anyone who has swum through water with blue-green algae should wash themselves with soap and change their swimwear immediately after swimming.
