Counties.

* WHEN...For the High Surf Advisory, from 5 AM early this

* IMPACTS...Strong northeast winds with large waves will result
in minor coastal flooding with pockets of moderate coastal flooding
over multiple high tide cycles from late Friday through the weekend.
The greatest risk for coastal flooding appears to be setting up
south of Boston and onto the Cape and Islands. In addition...the
long duration of northeast winds coupled with large waves over
multiple high tide cycles will result in areas of beach erosion
for a prolonged period.
