national weather service detroit/pontiac mi
346 pm edt sat jul 18 2026

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.

.synopsis...a low pressure system tracking through the northern
lakes region will drag a cold front through the eastern lakes
through this evening. high pressure will then build in tonight
and remain across the region through the rest of the weekend.
