for waters beyond five nautical miles off shore on lake huron

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

from the eastern plains on wednesday before a cold front tied to
a low, 29.30 inches, moves through wednesday night bringing in
stronger winds and waves.
