Near St. Lawrence Island
There is an area of consolidated pack ice along the coast east of Savoonga that extends up to 0.75 nm from shore. Extending north from that pack ice to the northeastern Russian coast is a band of open pack ice consisting of small to medium floes that ranges from 2 to 8 nm wide. The nearest sea ice to Gambell is open pack ice consisting of small floes approximately 18 nm northwest of Gambell.
The nearest sea ice to Nome is within Safety Harbor and Golovin Bay. There is also a band of open pack ice consisting of small to medium floes that runs north to south and ranges from 2 to 8 nm wide that is approximately 90 nm west of Nome.
Shorefast ice extends to approximately 3 nm west of Brevig Mission, then there is an area of sea ice free water to approximately 80 nm west of the edge of the shorefast ice where a band of open pack ice consisting of small to medium floes runs north to south. A small band of very open pack ice consisting of brash ice lies between Little Diomede and Big Diomede islands.
Wales to Shishmaref
Open water extends from the Wales to Shishmaref coastline to approximately 30 nm northwest of the coastline. There is then an area of close to very close pack ice consisting of brash ice to small floes extending another 12 to 15 nm from shore. A small band of very open pack ice consisting of brash ice lies between Little Diomede and Big Diomede islands.
A small band of very open pack ice consisting of brash ice lies between Little Diomede and Big Diomede islands.

There has been no ice for the past week, we are sea ice free and also the Snake River is currently open.
Observations from Wales
17 May 2019 – Robert Tokeinna, Jr.
Since the ice has gone out, there has been flow ice, but has since slowly pass by continuing north. Lots of southerly to east winds with some northeast n west wind last week during a night or so. Lots of cranes means spring has come for Wales, seen some snow geese and Geese also with duck and more Snow birds. Lots of water around town. Creek has drained but up towards the airport has alot of water. Local boaters went out unsure of catch. This ends my observation.
Observations from Port Clarence and Brevig Mission

Yesterday the channel about 2.5 miles west opened up to the open water, the Port Clarence bay is not safe anymore. The edge of the open water is about 1/2 a mile west now.
Observations from Shishmaref

Bounty from the sea and air, Young hunters caught a young male walrus close to town. Flock after flock Snow Geese passing by all morning flying low from fog overcast making for other young hunters waiting having a field day duck hunting.
Returning hunters reported bearded seals in the area in remaining scattered ice. Sea rough the other day and open ice free sea for past few weeks.
