...EXTREME VESSEL ICING POSSIBLE FROM AUGUSTINE SOUTH THROUGH
SHELIKOF STRAIT THURSDAY AFTERNOON THROUGH FRIDAY NIGHT...

Northwesterly storm-force winds with hurricane-force gusts in
combination with frigid Arctic air will likely lead to extreme
vessel icing at rates of 4 cm per hour or greater. The greatest
chance for extreme vessel icing in Shelikof Strait is along the
immediate coast of the Alaska Peninsula. Winds diminish on
Saturday which should cause icing rates to decrease through
Saturday.

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.
