The tropical depression off the North Carolina coast could strengthen into the hurricane season's second tropical storm during the night.
The National Hurricane Center says top sustained winds are 35 miles an hour, just four miles below the threshold for qualifying as a tropical storm.
It would be called Tropical Storm Beryl.
Tuesday evening the depression was centered about 180 miles southeast of Cape Hatteras. It's moving north at about six miles per hour. A slow turn toward the north-northwest or northwest is expected by Wednesday.
A hurricane hunter aircraft is checking out the depression. The hurricane center says there are no signs that the depression could ever reach hurricane strength - 74 miles per hour.
There's a tropical storm watch along the North Carolina coast.
