* WHAT...For the Coastal Flood Warning, up to one foot of inundation above ground level in low-lying areas near shorelines and tidal waterways (3.9 to 12.6 feet Mean Lower Low Water). For the High Surf Advisory, large breaking waves of 6 to 15 feet in the surf zone. * WHERE...Eastern Essex MA, Suffolk MA, Eastern Norfolk MA, Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA Counties. * WHEN...Until 8 PM EDT Sunday. * 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 today through the weekend. The water also may struggle to vacate the area after the high tides given persistent strong northeast winds. 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 severe beach erosion for a prolonged period. Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Inexperienced swimmers should remain out of the water due to dangerous surf conditions.
