One to 3 inches of rain is possible on the North Carolina coast Sunday night and Monday, the weather service says. The Newport/Morehead office says 2 to 4 inches are possible, with a chance of more in some areas.
Localized storm surge and flooding are also possible in the area, the NWS says. But threats remain limited.
The weather service's Wilmington office, which covers southeastern North Carolina and northeastern South Carolina, says the storm's main threats to the area are "dangerous rip currents and elevated seas offshore." Land impacts should be minimal.
Rip currents will be at threat in the area, the NWS says.
Dangerous surf conditions are expected across the Southeast coast for the next few days, forecasters say. Swells associated with the storm could cause life-threatening rip currents.
The NWS' Charleston office, which covers the southeastern portion of South Carolina, says the storm will stay east of the area, away from the South Carolina and Georgia coast.
Showers are expected in the area into late Sunday afternoon, with a "rumble of thunder" possible. Overnight should be dry, with thunderstorms and showers expected throughout Monday, the weather service says.
Arthur is expected to turn away from the east coast and should lose its "tropical characteristics" on Tuesday, the National Weather Service says.
