...EXTREME VESSEL ICING POSSIBLE FROM NORTH AND WEST OF NUNIVAK
ISLAND TO CAPE NEWENHAM SATURDAY THROUGH TUESDAY...

Northeasterly winds in combination with Arctic Air could lead to
extreme vessel icing at rates of 4 cm per hour or greater.

As colder air filters in from the Arctic over the weekend,
northeasterly winds will intensify across the eastern Bering Sea.
These factors will cause extreme freezing spray which will spread
south and west from the Kuskokwim Delta. Heavy to extreme
freezing spray will extend from Cape Newenham to north and west of
Nunivak Island by Saturday. Areas of extremem freezing spray is
possible through Kvichak Bay as well. It will likely last through
Tuesday.

Operating a vessel in heavy to extreme freezing spray is
hazardous. Freezing spray may render mechanical and electronic
components inoperable. Rapid ice accretion on decks and
superstructures may result in catastrophic loss of stability.
