The forecast is for the subtropical depression to reach tropical storm strength — sustained winds of 39 mph or above — by midday Wednesday.

If it does get this strong, the storm will become Dolly.

“The good news is that the storm is expected to be around for only a brief period of time and is moving away from the US into the open waters of the North Atlantic,” CNN meteorologist Taylor Ward said.

By Tuesday afternoon or evening, the storm should begin weakening.

The storm system should be absorbed by a larger extratropical low or dissipate on Thursday, the National Hurricane Center said.
