RALEIGH, N.C. — Tropical Storm Cristobal dumped rain and brought rough seas to the North Carolina coast yesterday, and forecasters predicted the weakening system was headed for the open Atlantic.

At 5 p.m., the National Hurricane Center said the center of the storm had moved to 45 miles east of Cape Lookout and 40 miles south-southwest of Cape Hatteras with maximum sustained winds continuing at 45 mph. The storm was moving to the northeast at 8 mph.

The advisory said the storm’s center would head away from the coast early today.

The National Hurricane Center issued a tropical storm warning from Cape Lookout to the Virginia-North Carolina border, including Pamlico Sound.

The storm’s strongest winds were east of the center, out at sea, a National Weather Service meteorologist, Rich Bandy, said. Winds on the coastal side of the storm were about 25 mph and will have little impact on coastal cities unless the storm strengthens.

“There is a little more rain than earlier in the day,” Mr. Bandy said. “It’s not like the whole area is being inundated.”

Mr. Bandy said some rain was falling over the smoldering wildfire that has burned 64 square miles in Pocosin Lakes National Wildlife Refuge since it was started by lightning June 1.

“We’re still seeing fairly continuous bands of showers and isolated thunderstorms moving through eastern North Carolina,” a meteorologist at the National Weather Service bureau in Newport, Mark Willis, said. “There are going to be some areas that don’t receive anything and other areas will get several inches.”

The prospect of seeing Cristobal head out to see pleased a fishing captain standing on a dock at Ocracoke, an island south of Cape Hatteras.

“Let’s get it over with so we can go fishing,” Captain David Nagel, who has operated the “Drum Stick” charter boat for 31 years, said. “Nobody’s out. Everybody’s tied up.”

Mr. Nagel said he saw ominous clouds looming to the south and that the seas outside his harbor were 6 feet to 8 feet with winds blowing about 25 mph.

Rainfall was expected to be between 1 and 2 inches with isolated amounts of 4 to 5 inches in areas where heavy rain bands passed overhead, said Bandy.

Tony Spencer, who lives on Ocracoke and is chief of emergency management in Hyde County, which includes the island as well as mainland, said he had seen “very minor rain.

“It’s been really almost nothing,” Spencer said. “No downpours, just sprinkles.”
