Subtropical Storm Joyce has drifted southward in the open Atlantic with no change to strength, winds at 45 mph with higher gusts.

UPDATE 5 PM 9/12/18
Subtropical Storm Joyce has formed in the north Atlantic.
Joyce formed from an area of low pressure about 800 miles west southwest of the Azores. The National Hurricane Center says Joyce has 'developed a cyclonically curved band of deep convection near the center.'
As of the 5pm advisory, Joyce has maximum sustained winds of 45 mph and is moving southwest at 6 mph.
Joyce may acquire tropical characteristics over the coming days and could strengthen a bit. However, Joyce is moving nowhere near the United States and won't be a threat to land.
