I see much bigger and clearer openings now in the Chukchi and Beaufort Seas than there were a year ago.

Is there anything else in the images that you would like to draw our attention to?

The middle of the image shows a pretty large gap where the year before, it was ice covered. I think this was what you referenced D

From what I understand, this is where you go to see the ice flowing past, it's just this year the amount is noticeably more so the locals are talking about it.


Ah, we were in Lewisporte, up the arm from Twillingate this AM. The ice appears to run all the way up there and the harbor entrance appears choked. No rush to get the boat in right now. Brrrrr. That ice makes the wind cold.

Yes, comfort food. Fight Duff!

To separate "ice" from "bergs" to a bit what is "normal" is for the ice coming down off Labrador and Baffin to float across the Labrador Sea a couple of hundred miles North of Newfoundland. It can make a fairly impenatrable bar. It's one of the things that you have to pay attention to when planning to go to Greenland early in the season.

I'm not 100% sure but my guess is that the big wind they had up here a while ago pushed this ice South and mushed it all up against the shore instead of wher it's supposed to be.

The spring ice floes are not all that consistent or predictable. Lots of different forces going on. People don't go out into the ice sealing like they did a century ago. So we loose our popular awareness of how it works. Even so, just a few years ago the few boys who went out sealing in their 45' to 60' boats got caught and had to be rescued. One or two boats sunk. A couple of crews had to be evacuated because of lacking provisions. They finally got a cutter in there and it made a sweeping swath breaking the ice. As she cut a path the boats fell in behind her and they all came home like ducklings behind the hen.

The circulation just to the Siberian side of the North Pole now has a pressure at one place in its center of 985 hPa:

If it were a tropical cyclone, that would put it (barely) within the Category 2 range.

And now there's an even bigger cyclone predicted in just a few days:

GFS 12z op run: 967 hpa bomb cyclone at +126h

The low pressure over Siberia to the south of Novaya Zemlya has central pressure of 984 hPa. These are some nasty low pressure systems. The other low pressure systems seen on the dynamic map don't compare.
