Northeasterly winds in combination with Arctic Air surging south across the Bering Sea is likely to 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, northerly winds will intensify across the eastern Bering Sea. These factors will cause extreme freezing spray to 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 beginning Saturday morning. Extreme freezing spray is also possible out of Kvichak Bay as far west as Cape Constantine. Winds diminish on Monday, which should cause icing rates to decrease by Monday afternoon. 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. $$ Quesada
