When the storm is in this stage, forecasting an accurate path is hard as herding cats, regardless of the weather model, despite the availability of live data from so many reliable sources, such as temperature, humidity, wind speed, air pressure as well as water temperature and salinity of water - and at multiple levels of the atmosphere.
