Weather Forecast North East West passage -03 Spt- day 52
General situation
The main player on the synoptic maps becomes and remains the powerful and persistent high pressure system over the Beaufort Sea. Between this system and the migratory depressions over the Southern parts of the Chukchi and Bering Sea, a strong Easterly is maintained over the largest parts of the C-sea. Fortunately one of those moving depressions gave us some veering winds last night and also a part of today. However, as said yesterday, the wind is going to back again to the East after 18utc.
Than you will have probably 6 to 9 hours S to SE’ly wind, so continue Eastwards. Between 9 and 12utc (4Sept) the wind goes back to the East, from this point you can add the Northerly component in your track (at this point you should be fairly close to the coast).
(All forecasted winds are average values).
