  superstructures may result in a catastrophic loss of 
  stability. Very 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 remain in port, alter course, and/or secure the
vessel for severe conditions.

CDT TUESDAY...

* WHAT...For the Storm Warning, north winds 30 to 40 kt with 
  gusts up to 55 kt and waves 16 to 21 ft. For the Heavy 
  Freezing Spray Warning, heavy freezing spray at a rate of 2 cm 
  per hour or greater expected, and may rapidly accumulate on 
  vessels. For the Gale Warning, northwest winds 25 to 35 kt 
  with gusts up to 40 kt and waves 11 to 16 ft expected.

* 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. Very 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 remain in port, alter course, and/or secure the
