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...Southwest winds continue through this evening. A cold

front moves through tonight into tomorrow morning which veers

wind direction from southwest to north. Behind the front, winds

across the region will be lighter and variable in direction.

Another low pressure system organizes well south of the area

Tuesday into Wednesday, favoring the gradual development of

northeast winds. As this low moves over the Northeast mid to late

week, northeast winds will back from the northeast to northerly,

and eventually take on a more westerly component by Thursday.
