"High seas ahead!"

I can't say if we'll get any rain from Irene,

But from the looks of this map we should be in for some waves.

Irene may not bring much rain or wind, but we could see some surf.

However, not being an oceanographer, I cannot speak precisely as to what SWAN Significant Wave Height means. According to Wikipedia it is defined as “the average wave height (form trough to crest) of the one-third largest waves.”


If I'm reading the legend correctly ....

That's some pretty high seas!
