As we have seen in past winters, ice in the Pacific Arctic tends to grow in fits and spurts, often alternating between Bering and Okhotsk Seas. This see saw began late December with Bering adding ice to surpass 2018 maximum in that basin, while Okhotsk paused. The above image of the first two weeks of 2019 shows Okhotsk on the left growing ice while Bering pulled back a bit. Then in the last two days both basins added extents to set new highs for the season. Combined the two seas ice extents are slightly above the 12 year average at this time. With the disappearance of the Blob of warm water in the North Pacific, both basins appear to be in ice recovery mode.
