The storm is expected to hit Denmark on Saturday afternoon. The museum is located by Roskilde Fjord, where the water level can rise 1.9 meters.
The museum employees have set up defenses to ensure that seawater does not enter the buildings.
"Tomorrow, we will secure the ships in Vikingskipshallen by putting plastic over them," acting emergency manager Tom Nicolaisen at the museum stated.
The Viking Ship Museum in Roskilde exhibits five 1000-year-old original ship finds from the Viking Age, the so-called Skuldelev ships. It also hosts a fleet of sailing reconstructions.
The permanent exhibitions in the museum are focused on the five Skuldelev Ships. The exhibits tell the story of these ships and the related Nordic maritime adventures during the Viking Age.
The Skuldelev ships
As the Viking Ship Museum points out, a barrier system was established on Roskilde Fjord during the late Viking Age, making it possible to control the sea routes to one of Denmark's great royal cities.
Three worn-out ships were towed out to the narrowest point, just outside the village of Skuldelev, filled with stones and sunk in the sailing channel Peberrenden, the most direct route to Roskilde.
After twenty years, the barrier was reinforced with two more ships to create an effective defense system.
