Weather Forecast North East West passage -05 Spt- day 54
General situation
A pretty deep depression develops over the Bering Sea whilst a large high pressure system cover the best parts of the Beaufort Sea. In between those two pressure systems a strong Easterly windfield is maintained. This situation seems to be rather persistent, next week as well and triggers some strong Easterly wind over the Southern parts of the Beaufort Sea. Especially the seventh of September the stretch beyond Point Barrow seems to be very windy.
On the 8th a low pressure trough will gradually extend towards the Southern parts of the Beaufort Sea. This results in easing and turning winds on the 8th.
However details in local wind conditions can still change and might offer different possibilities to progress Eastwards.
