From Tuesday afternoon southwesterly near-gale force 7, occasionally gale force 8. Late Tuesday evening and Wednesday early morning possibly severe-gale force 9. If the engine stops you can float away from land. Risk of dangerous situations when in a small boat at sea. Very high waves. Considerable tumbling of waves with heavy impact. Reduced visibility. Do not go out at sea in a small boat

From Wednesday evening through Friday morning locally up to 20-30 cm of snow in 24 hours is expected. Most likely areas to get snow are areas above 200 m.a.s.l. and inland regions. Most snow is expected during the night. Vulnerable infrastructure can be affected due to accumulation of snow. Travel time may increase on some journeys. Local driving conditions may become difficult. Blowing snow at higher altitudes causes reduced visibility and possibly convoys and/or closed roads. Vulnerable installations and objects should be protected. Allow some extra time for transportation and driving. Use tires fit for winter conditions and use caution while driving. The need for emergency preparedness shall be assessed continuously by emergency response actors.

High water level is expected late Wednesday evening and early Thursday morning. More information about timing of high water level and values for positions along the coast at sehavniva.no. The uncertainty of the predicted water level is 5-10 cm. Flooding may cause water damage to infrastructure and buildings a few places in the coastal zone. Wind and waves in combination with high water level may cause minor damage to infrastructure and buildings in the coastal zone. Due to high waves be careful in coastal areas. Check the mooring of the boat and secure objects inside boathouses and in the coastal zone.
