closeLocally moderate to severe vessel icing is expected in coastal and fjord districts.
Area
Applies to Troms.
Instructions
Rapidly remove ice from the boat.
Consequences
Rapid ice accumulation on a small boat may cause it to lose its stability, tip over and sink. For ships the issue is more directed towards slippery decks, handrailing, ladders, iced down safety boats and safety equipment. Ice accumulation may also damage radio communication if the antennas are freezing. High ice accumulation on the bow/bridge of the ship.

Orange - considerable dangerRead more about the severity levels at hjelp.yr.no
From Thursday afternoon east and southeasterly storm with extreme gust locally with 35-50 m/s. There are expected strongest winds from Thursday afternoon until Friday evening. There will be large variations in wind speed. Some places may have calm conditions while other places experience extreme wind gusts. In addition the temperature at exposed places is expected to be in -the range of 10 to -15 degrees. The combination storm and low temperatures could cause challenges for power delivery, there is potenial for frost bite and risk of moderate to severe icing on ships.
Area
Applies to North-Helgeland, Salten, Ofoten and Troms.
Instructions
Follow the advice of emergency authorities. If you MUST drive, follow the advice from the Norwegian Public Roads Administration and check road reports (175.no). Follow advice and check status from transport operators. Prepare your home for a potentially long power outage. The need for emergency preparedness shall be assessed continuously by emergency response actors. In advance consider measures to limit damage.
Consequences
It is dangerous to be outdoors, and unusually large damage to buildings, infrastructure, forests and power supplies is expected. Expect cancelled departures for ferry, plane, or other transport. Bridges may be closed. Ceiling tiles blow off houses and buildings. Allow a lot of extra time for transportation and driving, even for short journeys. The power supply locally will be significantly affected. Many roads may be closed due to trees or other objects. Blowing snow causes reduced visibility and possibly convoys and/or closed roads. The strong wind may cause locally high waves in fjords and lakes.
