(CNN) -- Hurricane Arthur is about to make landfall at Cape Lookout, North Carolina, the National Weather Service said late Thursday.

Rain was intermittently heavy throughout the day in much of the southeastern parts of the state.

The National Weather Service in Wilmington said 1 1/3 inches of rain fell during one hour Thursday afternoon. The office also tweeted that there was some flooding just south of downtown.

The storm's strongest sustained winds were 100 mph.

North Carolina Gov. Pat McCrory told residents and tourists to stay inside while it was dark outside. He said the potential track for the storm would move it closer to land.

"We did not expect this western movement," he told reporters Thursday night. "So we're most concerned now about flooding inland and storm surges in our sounds and in our rivers."

There were no immediate reports of injuries and some counties reported only minimal damage.

The good news: the storm hit Thursday at low tide, the governor said. The bad news: the storm was now stronger.
