According to the Federal Maritime and Hydrographic Agency (BSH), there is a risk of a storm surge on the German North Sea coast on Wednesday. As the Hamburg authorities announced on Wednesday morning, the high water in the morning and at noon on the East Frisian coast and in the Weser area will be three quarters to one meter higher than normal.
On the North Frisian coast, the experts expect water levels to be one to 1.5 meters higher. In the Hamburg Elbe area, the tide can be about 1.5 meters higher than the average high tide, it said. The storm surge danger is therefore until about 1 p.m.
On the North Sea coast, the BSH speaks of a storm surge when the flood water is at least 1.5 meters higher than normal. A severe or very severe storm surge is only spoken of from values of 2.5 or 3.5 meters.
According to the German Weather Service (DWD), a low spur causes stormy weather in the north on Wednesday. On the North Sea coast, the meteorologists expect gusts of wind with wind speeds of up to 85 kilometers per hour (wind force 9). In exposed locations, such as on the North Sea islands, severe gusts of wind of magnitude 10 are also possible. There are also gusts of wind inland.
