URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
418 AM EDT Wed Oct 16 2019

...Northwest gales today and Thursday...

.A strong low pressure system anchored over central lake Huron today
will gradually exit toward the northeast tonight. This process will
draw colder air into the region on increasing northwest winds,
particularly from this afternoon into tonight. This will lead to an
extended period of gales lasting through Thursday over much of lake
Huron. Gusts across the central basin of lake Huron will approach 40
knots at time during the peak early tonight. These winds will bring
high wave action, likely reaching over 12 feet at times across much
of the open waters. Small craft conditions will exist for the
remainder of the region. The eastward exit of this system will bring
improving conditions Thursday night, with modest winds and waves
lasting through Friday as high pressure enters the region.
