A level 1 was issued for North sea and coastal areas of Netherlands, NW Germany and parts of Denmark mainly for funnel clouds and non-mesocyclonic tornadoes (waterspouts).
Behind the rapidly SE-wards moving strong surface cold front, polar airmass will be spreading across the North sea and coastal areas of Netherlands, extreme NW Germany and Denmark. Models release a marginal instability once the steep lapse rates overspread the still warm SSTs there. Given the low EL temperatures, CAPE will be tied in the lowest levels and combined with steep LL lapse rates and weak shear (although surface winds will be quite strong from the NW), shallow convection is likely within the maritime airmass. A couple of funnel clouds or waterspouts could occur in these conditions as well. However, a marginal level 1 threat area has been placed over parts where the potential for some spout type tornadoes or some strong gusts seems maximized.
