Possibly the best model ensemble this year is the Google DeepMind, and it is not a bad one to give some credence to for as far out as 10 days.

Today's most recent 240 hour (10 day) outlook from the DeepMind continues to show a sizeable number of its ensemble members developing this wave in the Caribbean, with most of these then also showing a near collapse of steering currents, with the forecast future cyclone meandering about for a bit. Beyond ten days this model does show more of them moving the system, but beyond ten days is also pushing the capabilities even for this excellent model.
