* WHERE...Lake Michigan nearshore waters from Washington Island
to Sheboygan.
* WHEN...For the Small Craft Advisory, from midnight tonight to
6 PM CST Wednesday. For the Heavy Freezing Spray Warning, from
3 AM to noon CST Wednesday.
* 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. Conditions will be hazardous to small craft.
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.
Inexperienced mariners, especially those operating smaller
vessels, should avoid navigating in hazardous conditions.
