MIAMI, Sept. 8 (UPI) -- A subtropical storm formed with 40 mph winds Sunday 410 miles southeast of Cape Hatteras, N.C., and moved northwest toward land at 13 mph, the National Hurricane Center said.
It was named Gustav, and a tropical storm watch was issued for Cape Fear, N.C. north to the North Carolina-Virginia border. A tropical storm watch means that tropical storm conditions are possible within the watch area, generally within 36 hours.
At 5 p.m. EDT, Gustav was located near latitude 30.6 north, longitude 71.4 west. Forecaster James Franklin said that on its current track the storm will approach the Mid-Atlantic Coast late Monday or early Tuesday.
Some strengthening is expected, he said.
A new tropical depression also developed over the weekend. It had winds of 30 mph, but it quickly dissipated Sunday, 950 miles southeast of Bermuda.
