    From Wednesday morning to Wednesday evening expected south and southeast severe gale force 9, and occasionally storm force 10 in exposed places. In conjunction with the strong wind there are expected severe gusts in the range of 25-33 m/s. There is also possibility for locally very severe gusts in the range of 33-37 m/s. The strongest gusts are expected at exposed places between Lyngsalpan and Porsanger, but the very severe gusts are not expected to affect populated areas. There is also expected that many areas will not be affected by the severe gusts at all, and it is unpredictable where the strongest wind will burst down from higher elevations and where the wind will blow over leaving the lower areas unaffected.
