Gale Watch


URGENT - MARINE WEATHER MESSAGE
National Weather Service Detroit/Pontiac MI
1000 AM EDT Tue Oct 16 2018

...Gusts to gales today and possibly Wednesday...

.Northwest gales over the open waters of Lake Huron have settled down
to around 30 knots during the early morning. The wind will now shift
southwest and increase again into the 35 to 40 knot gale range
through today affecting mainly Saginaw Bay along with central and
northern Lake Huron. Gale Warnings remain in effect through this
evening for Saginaw Bay and Lake Huron north of Harbor Beach. Small
Craft Advisories remain in effect for all other marine areas through
western Lake Erie.

Gales subside to gusts around 30 knots by mid evening through the
overnight as the pressure gradient relaxes in the vicinity of the
cold front moving through the central Great Lakes. However, wind
veers and strengthens Wednesday with northwest gales possible once
again. Given the lengthy break tonight, and some uncertainty on
timing and magnitude Wednesday, a Gale Watch has been issued for
central and northern Lake Huron for Wednesday into Wednesday evening.
High pressure then builds into the Ohio valley and southern Great
Lakes for a short time through Thursday before the active weather
pattern resumes with another strong cold front Friday night.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Gale Warning means winds of 34 to 47 knots are imminent or
occuring. Operating a vessel in gale conditions requires
experience and properly equipped vessels. It is highly
recommended that mariners without the proper experience seek safe
harbor prior to the onset of gale conditions.

A Gale Watch is issued when the risk of gale force winds of 34 to
47 knots has significantly increased...but the specific timing
and/or location is still uncertain. It is intended to provide
additional lead time for mariners who may wish to consider
altering their plans.
