People navigate the wind and rain along King Street during Hurricane Dorian in Charleston

People navigate the wind and rain along King Street as Hurricane Dorian sweeps past Charleston, S.C., on Thursday. Rain and wind are expected to arrive in New Hampshire Friday and Saturday.

HAMPTON — Hurricane Dorian will pass well off the New England coast, but the once powerful tropical system is still expected to bring clouds, showers and building seas along New Hampshire’s coastline.

Forecasters are warning people to be aware of rip currents as Dorian churns up the Atlantic and waves increase from 6 to 7 feet Saturday morning to 9 to 10 feet by the evening.

“The wave action will be the big thing,” said William Watson, a meteorologist with the National Weather Service in Gray, Maine.

Clouds associated with Dorian began moving into southern New Hampshire on Thursday and were expected to continue northward as the deadly hurricane that ravaged the Bahamas moved along the Carolina coastline with maximum sustained winds of 105 mph.

Coastal areas of New England will likely see some showers from Dorian by Friday night with breezy conditions.

The projected track will take Dorian south and east of Cape Cod, Mass., where a tropical storm warning was issued.

Watson said the biggest waves will be on Saturday, which is when the coast could also see the strongest rip current, some beach erosion and splashover in some areas.

Seas will subside by Sunday morning, he said.

Watson said spectators hoping to catch some wave action need to be cautious.

“You may be curious, but be careful. We’d rather you not venture out on the rocks to avoid getting swept off,” he said.

Hampton Fire Chief Jameson Ayotte also urged beach-goers to heed warnings if visiting the coast this weekend.

“Follow all lifeguard recommendations. If swimming is prohibited it is for your safety,” he said.
