...HEAVY FREEZING SPRAY WATCH NOW IN EFFECT FROM SATURDAY
AFTERNOON THROUGH MONDAY MORNING...

* WHAT...For the Gale Watch, north winds 25 to 35 kt with gusts 
  up to 40 kt and seas 7 to 10 feet possible. For the Heavy 
  Freezing Spray Watch, heavy freezing spray at a rate of 2 cm 
  per hour or greater possible, and may rapidly accumulate on 
  vessels.

* WHERE...Portions of Massachusetts coastal waters and Rhode 
  Island coastal waters. 

* WHEN...For the Gale Watch, from Saturday afternoon through 
  Sunday afternoon. For the Heavy Freezing Spray Watch, from 
  Saturday afternoon through Monday morning.

* 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 can cause hazardous seas which could capsize or
  damage vessels and reduce visibility.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Mariners should consider altering plans to avoid or mitigate
hazardous accumulation of ice on their vessel. During freezing
spray conditions, the U.S. Coast Guard advises mariners to check
and ensure all life-saving  devices remain free of ice. 

Mariners should consider altering plans to avoid possible
hazardous conditions.  Remain in port, seek safe harbor, alter
course, and/or secure the vessel for severe wind and seas.
