Debby tracker: Post-tropical cyclone still dumping rain; new tropical wave forming

Forecasters are continuing to track storm Debby, now a post-tropical cyclone, as it continues to move northward and dump rain over Mid-Atlantic states, as well as a new tropical wave forming out on the Atlantic.

According to an advisory from the National Hurricane Center, Post-Tropical Cyclone Debby is shifting northward Friday, bringing heavy rainfall and a "significant flood threat" from the northern Mid-Atlantic states into Upstate New York. Further south, heavy rainfall is expected across portions of the coastal Carolinas Friday, with areas of considerable flooding.

There was also risk for a few tornadoes early Friday morning from eastern North Carolina, into Virginia and Maryland, and the threat for tornadoes moves north into New Jersey, eastern Pennsylvania and eastern New York Friday.

Forecasters eyeing new tropical wave forming

Forecasters are also tracking a tropical wave over the tropical Atlantic, several hundred miles west-southwest of the Cabo Verde Islands off the coast of Africa, producing "widespread disorganized showers and thunderstorms." Any development of the tropical wave should be slow to happen over the next few days, forecasters said, as it moves west across the central tropical Atlantic.

The current formation chance through the next 48 hours is near 0%, with a 50% chance for formation over the next seven days.

After, a tropical depression could form while it approaches the Lesser Antilles in the Caribbean by early next week, and could approach the Greater Antilles by the middle of next week.

If it does become a named storm, it will be called Ernesto.
