Update 12 minutes ago:
Norwegian public broadcaster NRK said the Viking Sky’s evacuation was likely to be a slow and dangerous process, as passengers needed to be hoisted from the cruise ship to the five available helicopters one by one. By 6 p.m. local time, some 100 people had been rescued.
Authorities told NRK that a strong storm with high waves was preventing rescue workers from using life boats or other vessels in taking passengers ashore.
A good reason to stay away from crowds.
