for waters beyond five nautical miles of shore on lake michigan.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

winds will increase from the southeast this morning as low 
pressure around 29.8 inches tracks across ks to the south tip of 
lake michigan into tonight. there will be a brief six hour window
of south to southeasterly gales late this afternoon and early 
evening for the southern third of the lake. winds will weaken 
below gales as the low pressure passes the southern tip of lake 
michigan overnight saturday. stronger northwesterly winds will 
then develop sunday into sunday evening and may reach gale force 
as the strengthening low pressure area moves away. thus a gale 
watch is in effect for sunday and sunday evening for the entire 
open lake. high pressure will then build in later sunday into the 
start of next week with light winds.
