Oscar has made the transition to a tropical storm with 65 mph winds. It will remain in an area of moderate shear and relatively warm water so strengthening is expected. It will likely become a hurricane later today.

A trough moving off the East Coast of the United States will steer Oscar to the northeast over the northern Atlantic. The system will remain far removed from any land areas. By Day 4, shear increases and Oscar will become extratropical cyclone and weaken.
