* WHAT...For the Small Craft Advisory, southwest winds 15 to 20
  knots and waves 4 to 6 feet. For the Gale Warning, northwest
  winds 25 to 35 knots and waves 8 to 13 feet expected. For the

* WHEN...For the Small Craft Advisory, until 1 AM EST Monday.
  For the Gale Warning, from 1 AM to 7 PM EST Monday. For the
  Heavy Freezing Spray Warning, from 1 AM Monday to 7 AM EST
  Tuesday.

* 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.
