Waves are the significant wave height - the average of the highest

the highest 1/10 of the wave spectrum.

.SYNOPSIS...An expansive 30.2 inch high will settle across the
Mid-Atlantic coast this evening. A 29.5 inch low will then slowly
cross the Upper Great Lakes tonight and Thursday. This low will
push a warm front across the lake Thursday...with the front
oscillating back and forth over the region Friday and Saturday. A
deepening area of low pressure to 29.4 inches will lift northward
across the Central Great Lakes Saturday and to near James Bay
Sunday, while pushing the oscillating frontal boundary eastward of
the lake as a cold front Saturday night. Then a 30.0 inch high
will build across the mid-west Sunday and nudge into the Lower
Great Lakes on Monday.
