Six to ten foot waves are expected to batter the Seacoast today as Hurricane Erin passes by the region.
The National Weather Service issued a Coastal Flood Advisory for the coastline of New Hampshire and up through Southern Maine through 1 a.m. Saturday. A High Surf Alert continues to be in effect through 8 p.m. on Saturday.
"Flooding of lots, parks, and roads with only isolated road closures expected. Dangerous swimming and surfing conditions and localized beach erosion," Coastal Flood Advisory said.
Rip currents continue to be a concern as well as the swell from Hurricane Erin hits the shoreline. According to NWS, the swell will "continue to build into the weekend and will be slow to subside early next week."
"Inexperienced swimmers should remain out of the water due to dangerous surf conditions," NWS said. "Large waves can present a danger to people on rocks above the water. Stay away from rock outcrops along the shoreline exposed to ocean wave as waves can easily sweep people into the cold ocean water."

Where is Hurricane Erin?
The latest Hurricane Weather Center advisory, released at 5 a.m. ET on Aug. 22, shows that Erin is located about 425 miles south-southwest of Halifax, Nova Scotia with maximum sustained winds near 90 mph with higher gusts. Forecasters predict that Erin will likely transition to a post-tropical storm by Friday night, Aug. 22, but will continue to be a "powerful hurricane-force low pressure system" through the weekend.
Erin is currently moving northeastward at 22 mph, with a turn toward the east-northeast expected later on Friday, August 22. The storm is then forecast to turn back toward the northeast on Sunday, August 24. The center of Erin is anticipated to pass south of Atlantic Canada throughout the day on Aug. 22 and then race across the north Atlantic waters.
Forecasters said tropical storm-force winds are possible in extreme southeastern Massachusetts during the next couple of hours, with gusts to gale force possible along portions of Nova Scotia and the Avalon Peninsula of Newfoundland on Saturday, Aug. 23.
