New storm forms in Atlantic Ocean

MIAMI -- Subtropical Storm Jerry formed Sunday in the Atlantic Ocean but posed no immediate threat to land, the National Hurricane Center said.

Forecasters said the storm was moving north around 6 mph and is expected to remain over open waters, far west of the Azores.

Subtropical storms are hybrid systems that get energy from warm waters like tropical ones, but also from colliding warm and cold air masses like more common storms over land.

Jerry is the 10th named storm of the Atlantic season.

In the Pacific, Ivo was downgraded from a tropical storm to a depression early Sunday, the Hurricane Center said.

The depression -- which had maximum sustained winds of 30 mph -- is expected to pass over or near the southern tip of Baja near the resort cities of Cabo San Lucas and San Jose del Cabo, a region that was hit early this month by Hurricane Henriette. Rainfall of 1 to 2 inches is forecast for the area.
