Tropical Storm Arthur is leaving the Florida coast and heading north with sustained winds of 60 miles per hour.

The National Hurricane Center has issued a tropical storm warning for parts of North Carolina.

Tropical storm conditions are expected in the area spanning the Little River Inlet to the North Carolina-Virginia border within the next 36 hours.

As of 11 a.m. Wednesday, Arthur was about 105 miles east-northeast of Cape Canaveral and about 260 miles south-southeast of Charleston, South Carolina. It is moving north about 7 mph with maximum sustained winds of 60 mph.

A tropical storm watch for Florida has been discontinued.

Forecasters expect Arthur to strengthen into a hurricane by Thursday and skim North Carolina's popular, flood-prone Outer Banks on Friday.

Reid Weisman, an astronaut with NASA, tweeted a photo from space showing the large size of the storm.

He tweeted: "Just flew over TS Arthur - Hoping it heads to sea. Looks mean."
