The limit for hurricane wind strength on the Beaufort wind scale is 32 meters per second. At 09.45 the wind gauge for Portwind.no showed that there was a gust of 42.1 m/s, according to Lofotposten. – When the anemometer blacked out, Arild Karlsen at the Stamsund ship expedition tells news. It happened at the same time that parts of Stamsund lost power, so Karlsen does not know how strong the wind was at its strongest. Sailboat on a rack in Fauske harbour.

Beaufort scale Hurricane >32.7- Strong storm 28.5-32.6 m/s Full storm 24.5-28.4 m/s Small storm 20.8-24.4 m/s Strong gale 17.2- 20.7 m/s Stiff gale 13.9-17.1 m/s Light gale 10.8-13.8 m/s Fresh breeze 8.0-10.7 m/s Beaufort’s scale indicates average wind strength and not strength in the gusts of wind. Source: Metlex Meteorologist: – Never seen such strong winds – I don’t think I’ve seen such strong average winds previously recorded on the coast of Troms. This is what state meteorologist Eirik Samuelsen writes on his unofficial “Eirik’s weather blog” on Facebook. The roof of the municipal building in Hamarøy was blown off in the strong wind. Photo: Truls Johnsen – Måsvik on Rebbenesøya on the outer side of Troms just registered a max. average wind in the last hour of a whopping 37.0 meters per second. This is a clear hurricane with a good margin. This is therefore an average wind recorded during 10 minutes. – A quick search shows that probably only Torsvåg’s 39.1 meters per second from 30 March 1991 is stronger than what we have of wind measurements on the coast of Troms, but in 1991 we did not have measurements on Måsøy. The strongest gust on Måsøy has been a whopping 45.5 meters per second until now. Here we see how strong the wind was in Nordland and Troms on Monday morning. Photo: Meteorological Institute In the mountains in Nordland, there are completely “wild values”, writes Samuelsen further: Glomfjord-Tverrfjellet has had 41.9 m/si average wind (hurricane) and a gust of as much as 64.1 m/s. Fagernesfjellet has had 48.1 m/s (hurricane), only 2.4 m/s from the mean wind record in Norway from Sluskfjellet from 2022. The strongest gust here has been 59.4 m/s. In Nordland, there are even more strong wind observations in the lowlands so far: Rotvær, strong storm, (32.2 m/s), gust 42.6 m/s Værøy Heliport, full storm (27.1 m/s), gust 41 .8 m/s Drag – Ajluokta, small gale (12.0 m/s), gust 40.7 m/s Helligvær II, strong storm (31.0 m/s), gust 40.7 m/s Myken, strong storm (29.7 m/s), wind gust 39.9 m/s Røst Airport, strong storm (30.4 m/s), wind gust 39.1 m/s Skrova Lighthouse, strong storm (29.0 m/ s), wind gust 38.7 m/s Bø i Vesterålen III (27.6 m/s), wind gust 38.0 m/s Assessed extreme weather forecast The meteorologists in Northern Norway say that they assessed both yesterday and today whether it was basis for issuing an extreme warning. But they concluded that this is not extreme weather. – We have an orange warning with the possibility of extremes. So it’s completely in the borderland based on the forecast we have out, says Jon Austerheim, on-duty meteorologist at the Weather Forecast for Northern Norway. The criteria is that you must have 45 meters per second wind along the coast. The roof of the local company Spinneriet at Storjord i Rana also lost its roof in the strong wind on Monday. Photo: Lars-Petter Kalkenberg / news – So it is probably in borderland, you could say, and Røst has been around 40 meters per second. – It does not meet the criteria we have for sending out a red danger warning as an extreme warning. It is likely that there are storm centers that pass some distance out to sea. He thinks it’s understandable if people think it’s extreme. – It is extremely opposite. Austerheim says that the difference is not particularly large. – Orange warning is more than enough to be quite dangerous in many situations. A little depends on where you are and what kind of activity you are doing. It’s probably a good idea to stay inside. There were many people who sought out the storm on the pier in Bodø today. Photo: tipser – But have you considered changing the warning? – Yes, we consider it all the time, but now the wind is waning again in Nordland. While further north it blows up during the afternoon and evening. Troms is at its strongest now, or will be shortly. In West Finnmark, it will get a little worse in the afternoon now. What is extreme weather? Extreme weather is rare weather that leads to great danger to life and property. It could be, for example, strong wind, unusually heavy torrential rain or a heat wave. The criterion for being able to call a weather situation extreme weather is strict with a warning meteorologist: The weather must very likely cause very large damages or extraordinary danger to life and property in a land area of significant size. From a climate perspective, a weather situation is considered extreme weather if it is rare and at the extremes of historical observations. With global warming, the frequency of some types of extreme weather is increasing. We are constantly setting new temperature and precipitation records. In addition, it appears that the intensity of the weather is increasing, for example that the torrential rain will become even stronger in the future. In addition, we expect more frequent heat waves, also in Norway. Source: Meteorological Institute
