...GALE WARNING REMAINS IN EFFECT UNTIL 3 AM CST EARLY THIS
MORNING...
...HEAVY FREEZING SPRAY WARNING REMAINS IN EFFECT UNTIL 6 AM CST
EARLY THIS MORNING...

* WHAT...For the Gale Warning, west winds 25 to 30 kt with gusts
  up to 35 kt and waves 6 to 9 ft. For the Heavy Freezing Spray
  Warning, heavy freezing spray at a rate of 2 cm per hour or
  greater may rapidly accumulate on vessels.

* WHERE...Northern Open Waters of Lake Michigan, Lake Michigan
  from Sheboygan to Port Washington WI 5NM offshore to Mid Lake,
  and Lake Michigan from Whitehall to Pentwater MI 5NM offshore
  to Mid Lake.

* WHEN...For the Gale Warning, until 3 AM CST early this
  morning. For the Heavy Freezing Spray Warning, until 6 AM CST
  early this 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 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 severe conditions.
