URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
358 AM EST Tue Dec 10 2019

.Ongoing passage of a cold front will produce unsettled weather
across marine areas today. A slight decrease in wind intensity
occurs today, however, continued westerly flow draws in cold air
across the lakes, increasing instability and allowing stronger gusts
and elevated wave heights to persist. Small Craft Advisories remain
in effect and are extended through Wednesday for all nearshore zones
and a Gale Watch is in effect for northern Lake Huron.

In addition to wind, a primary hazard will then transition to snow
squalls starting today for all of Lake Huron reaching south down
into Saginaw Bay. The potential for snow squalls will continue
through Wednesday, thus any snow activity over the lake will have
the potential to quickly and drastically reduce visibilities. In
addition to squall activity, freezing spray will be another
potential hazard across Lake Huron for Wednesday.
