It had maximum sustained winds of 35 mph, moving northwest at 7 mph.

Initial forecasts predict the storm could go on to become Tropical Storm Nate by the time it makes it to the warm waters of the Gulf of Mexico. Once there, it could even become a hurricane.

If that's the case, Nate would be the 14th named storm and possibly the 9th hurricane of the season.

This year has been an especially active and destructive season with five major hurricanes and three U.S. hurricane landfalls.
