After the past week brought several days of flash flooding across Germany, scattered thunderstorms will lead to the continued threat for flooding through Sunday. However, most residents will see a welcome break from the rain early in the week as high pressure brings more settled weather.
Several days of heavy rain and thunderstorms over the past week have caused flooding in parts of Baden-Wurttemberg and Bavaria resulting in the death of at least eight people.
The first round of deadly flooding occurred on Sunday, May 29, and was followed by a second round on Wednesday.
The risk for flooding will continue as the slow-moving area of low pressure that caused daily downpours across southern Germany will remain in the area on Sunday.
Locations at risk for heavy thunderstorms include Munich, Stuttgart, Nuremberg, Frankfurt and Cologne. An afternoon thunderstorm could threaten Berlin as well, though the flood threat will not be as high as in areas farther to the south.
The strongest storms will be capable of producing rainfall in excess of 50 mm (2 inches) within an hour or two and damaging hail.
In addition to heavy rain and hail, thunderstorms will bring dangerous lightning. As reported by the BBC, at least 51 people were injured at a rock festival when lightning struck the venue very early on Saturday morning, local time.
The slow movement of these storms can lead to extreme rainfall in a short time period resulting in flash flooding.
"Areas in Baden-Wurttemberg and Bavaria that have already experienced flooding will be at an even higher risk for flooding on Sunday as downpours continue to fall on saturated ground and in areas with high river levels," AccuWeather Meteorologist Tyler Roys said.
"I must stress that if anyone comes across a flooded roadway, do not attempt to drive through the water," Roys said. "A driver won't be able to tell how strong the water flow is nor the depth of the water, which can cause cars to stall out. So turn around; don't drown."
After heavy downpours threaten to bring flooding on Sunday, high pressure moving to the south from Scandinavia will lead to the needed return of drier conditions to much of the country.
On Monday, slow-moving downpours are still expected to impact areas from Bavaria and Baden-Wurttemberg northward to North Rhine-Westphalia. These storms may bring isolated flash flooding, but the threat will be lower compared to past days. Much of the East will dry out.
By Tuesday, much of the country will see dry and warm conditions with the exception of isolated thunderstorms along the western boarder.
