National Hurricane Center: Subtropical Cyclone May Form Off U.S. East Coast

MIAMI, Florida – As of 8 a.m. Eastern Standard Time on Tuesday, September 22, 2015, the National Hurricane Center has issued a tropical outlook due to the presence of a non-tropical low pressure system located a couple of hundred miles southeast of Cape Hatteras, North Carolina,,

The system, dubbed Invest 97L, is producing disorganized showers and thunderstorms. According to NHC forecasters, upper-level winds are only marginally conducive for development and this system could possibly acquire some subtropical characteristics over the next couple of days while it moves slowly westward.

Invest 97L has a low chance (10%) of becoming a subtropical or tropical cyclone within the next 48 hours and a 20% chance for development over the next five days. Regardless of development, the system will still bring heavy rains and rough surf during the week to parts of Georgia, South Carolina, North Carolina, Virginia, and southern Delaware.

Spaghetti models for Invest 97L are not in agreement as to which direction this system may take. Most models predict that the system will make landfall somewhere along the U.S. East Coast between north Florida and southern New Jersey by Friday or Saturday.
