James Franklin , a meteorologist at the National Hurricane Center , said : The system was of frontal origin ... the frontal structure was eventually lost ... The convective structure resembled a tropical , rather than subtropical cyclone , and the radius of maximum winds ( based on QuikSCAT ) was very close to the center , also more typical of tropical cyclones ... on balance , it was more tropical than subtropical .
