Overnight model run summary:
Official forecast is for a tropical storm based on TVCN and Ships guidence, with the caveat that it does not match the global models. In short, it's not too reliable for intensity before it gets into the Gulf. However the reasoning is solid. Track is more reasonable, but the spread in the cone is there. In short things are a bit iffy in the forecast for the Gulf before the system is in the Gulf.

Euro ensemble spread:
