* WHAT...For the Heavy Freezing Spray Warning, heavy freezing
  spray at a rate of up to one inch per hour may rapidly
  accumulate on vessels. For the Small Craft Advisory, southwest
  winds 20 to 25 knots with gusts up to 30 knots and waves 5 to

* IMPACTS...Operating a vessel in heavy freezing spray is
  hazardous. Freezing spray may render mechanical and electronic
  components inoperative. Rapid ice accretion on decks and
  superstructures may result in a catastrophic loss of
  stability. Strong winds will cause hazardous waves which could
  capsize or damage vessels and reduce visibility.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Mariners should prepare for dangerous accumulation of ice on
their vessel. If possible, remain in port, avoid the warning area
or conduct mitigation.

Mariners should alter plans to avoid these hazardous conditions.
Remain in port, seek safe harbor, alter course, and/or secure the
vessel for hazardous conditions.
