Coastal Flood Advisory COASTAL FLOOD ADVISORY - Portsmouth Seacoast  - Rockingham
High Surf Advisory HIGH SURF ADVISORY - Portsmouth Seacoast  - Rockingham

Dangerous marine conditions continue through the weekend with large breaking waves and a high risk of rip currents. Splash-over and minor coastal flooding are possible for several high tide cycles through late this evening. This nor'easter will also lead to areas of widespread beneficial rain south of the mountains and gusty northeast winds through at least Monday along the coast and southern New Hampshire. It will turn drier and warmer once the storm moves away from the region by midweek.
